Performance and Stability Issues

I added a new user account to my Mac and it seems to have caused a bunch of problems. I can't eject a Tech Tool Pro disc--it doesn't appear in the Finder. When I try to reboot or log out, it times out and I have to use the power button. Installation programs have greyed out buttons. System Preferences and Disc Utility won't start. Some programs are operating slowly. Time Machine gets stuck in "preparing" mode. Tech Tool Pro hangs and won't force quit.
I recently used Disc Utility to format my external drive used for Time Machine backups, but didn't do anything to the boot disc. I also adjusted sharing permissions on my Documents folder and tweaked the user privileges.
Does anyone have an idea of what could be causing all of these symptoms, or a method for troubleshooting?

Try restarting while holding down a wired mouse button to eject the disk.
Sounds like you have pretty good Disk corruption going on. What version of TechToolPro are you using?
Did you try to repair the directory with it?
If the disk ejects, Try using Disk Utility to do a Disk Repair, as shown in this link, while booted up on your install disk.
If you own DiskWarrior run that. It's much better at directory repairs then TTP and DU.

  • Heavy FTP usage causing performance and stability issues

    We have been having out-of-the-ordinary issues with DMS for the last couple weeks. Examples:
    - There have been cases where certain people could not log in, while others could.
    - Increased numbers of help requests for "DMS not responding".
    - Search is getting slower because the statistics-and-analyze job has trouble running.
    We found the Node process was maxed out on memory. It turns out that FTP is served by the Node process. We believe that FTP usage has pushed the Node process to the breaking point.
    I would like to see if there is a way to increase server resources for FTP, like we can for Content processes like apps and dav. If that is not possible, we will have to limit FTP users to a number that can be supported by the limitations of the product. Since FTP has been very successful for us in handling many service requests, this would not be a good outcome.
    We tried setting the Node process' numprocs to 2, but the system wouldn't start. Another idea we have that might buy us a little is moving FTP to our 2nd apps server, whose Node process is only running one agent. Can we run FTP on multiple Nodes?
    I will put in a TAR for this, and post the number when I'm done.

    The TAR number is 6546521.992

  • Performance and stability in 10.4.7

    I've had numerous performance and stability issues since the 10.4.7 update. Most noticeable are:
    1) It often take a long time to focus on windows. When I click on, say, a Terminal window, the window raises immediately but is not active for about 1-2 seconds. (The close/minimize/maximize lights on the titlebar remain gray and the window is inactive.) During this time, the Terminal process is takes 50-90% of the CPU, and then the SystemUIServer process hogs the CPU for the following 1-2 seconds. This behavior is not exclusive to the Terminal process; it happens to other windows too.
    2) When the system has been on screensave for a long time (say, >1 day), it becomes unresponsive to keyboard and mouse input and won't wake up. I usually have to power down the computer and reboot.
    Has anyone else noticed this with the current OS? Could it be my fault somehow? If not, is it likely to be fixed in 10.4.8?
    MacBook Pro Mac OS X (10.4.7) 1.5 GB memory

    1) It often take a long time to focus on windows. When I click on, say, a Terminal window, the window raises immediately but is not active for about 1-2 seconds.

    This is unusual. My 10.4.7 is pretty instantaneous. It could be a sign that you are using something in the background that eats up the signal for graphics redraw. What third party software do you have installed? What peripherals do you have installed? Have you installed any Dashboard Widgets.
    2) When the system has been on screensave for a long time (say, >1 day), it becomes unresponsive to keyboard and mouse input and won't wake up. I usually have to power down the computer and reboot.
    Screen Saver or Energy Saver? Big difference here. Energy Saver could create such a situation especially with third party USB devices that are unfamiliar with Mac OS X's Energy Saver methods and send back signals expecting to receive back power and not getting it just as the machine wakes from sleep. If it is a Screen Saver, which Screen Saver? Have you tried to see if this happens without any pictures in your Pictures folder?
    Is your data backed up? Diagnosing issues which result from force shutting down may require hard drive repair utilities. And the same issues that come from that can have caused the freezing and slowdown you are experiencing, as well as show up on a hard drive that is dying. So it is critical your data is backed up before we diagnose further. See my FAQ on backing up:

  • Performance and Stability Problem with PE9

    I just upgraded my computer to a Core i5 with 8G of memory and everything is running much faster.  But my NEW PE9 just run very slow.  Some of the simple tasks take 10-30 second to complete.  Even Windows 7 will often come out to ask if I want to wait for PE9 to wake up or kill the process.  When I want to change the size of a video clip, it just doesn't work at all due to performance.  It will take PE9 20-30 seconds to resize the video clip.  Without some realtime feedback of the size, it is impossible to do the resizing and this is a very fundamental operation.  PE9 often crash or seize up as well, I didn't have any of these problem with PE3.0.  I upgraded to PE9 simply because my PE3.0 for WIndows XP is not comletely compatible with Windows 7 (some of the text displace does not show up).
    Do anyone else have issue with performance and stability?

  • Dreamweaver CS3 (9) maxed CPU slow performance and FTP issues.

    Dreamweaver CS3 (9) maxed CPU slow performance and FTP
    issues.
    Never mind...I found it.
    Of course I have all the firewall, worm, scanning, phishing
    filtering, full time protect, and everything else turned off when I
    am working on a remote/testing site however I found the Symantec
    antivirus email scan being enabled (doesn't it just interact with
    my email program?) was getting in the way of DW9 ftp operations,
    causing some lagging that was putting DW9 into an unstable mode
    during and immediately after (10 seconds) ftp operations.
    The CPU still spikes to 99% during ftp functions but DW9
    works even though it's likely taxed to the max but when I turn off
    email scan DW9 returned to a functioning state during ftp and
    remote file view. Whatever it takes huh?
    PS: email scanning only never effected DW8.02

    Thanks for the response. I managed to Google the 'nobody' account and found the explanation.
    As you say, I assumed the 'syslogd' process had to do with system logs. I did check the console and couldn't find anything of particular interest in the logs.
    I'll continue to monitor but if anyone has any further suggestions please post.
    One thing that might also have an impact... my available drive space is now down to less than 5gb (runs anywhere between 1gb and 5gb free depending on what I'm running). I know this causes problems for Parallels as it keeps moaning at me, but would it cause any problems with OSX?
    Thanks again,

  • Performance and Stability

    I was playing with the iMacs, mac mini and Mac Book Pros at the Apple store yesterday as I'm thinking about switching from Windows. I did a test where I opened several apps at once (Pages, Address Book, iCal, Garageband, iTunes) but found that every model would choke for minutes with the icon bouncing. Some would take so long that I gave up waiting for them to open and had to force quit.
    Do you normally have to only open one app at a time? Does OS X have any sort of app start-up caching?

    Opening several apps at once isn't a problem in Leopard 10.5.8. The more ram you have, the less problems you'll have opening a bunch of apps at once. Normally, the operating system isn't what determines whether you can open/run a bunch of apps simultaneously, it's memory (ram).
    Most of Apple's new machines ship with 1 or 2 GB ram. That's enough to run a few simple apps or one or two larger apps, but if you need to launch & run several complex applications at once, more ram in any system, mac or pc, will help.
    I have 11GB ram on my machine and can run every app on my system that I need simultaneously, including Word and the rest of the Office suite, Photoshop, Illustrator, Bridge, Flash, Dreamweaver, 3 browsers, EyeTV and several others with no problem. Several of those apps are set to launch at startup (which I don't recommend unless you know they won't cause conflicts) and most require lots of ram.
    I have never had an issue with that until recently when I installed Snow Leopard 10.6. I had so many problems system-wide with crashes and other issues, that I had to remove the new OS and replace it with a backed up version of my previous OS (10.5.8).
    If you're thinking about purchasing a Mac this time around, I'm sure you'll be happy with any machine you buy. Just make sure it doesn't have Snow Leopard and you'll be fine. Purchase and install extra ram and wait for Apple to fix the new operating system before upgrading to Snow Leopard 10.6.

    Hardware:
    17" Powerbook G4 1.67GHz with 2GB ram
    System:

    *Ever since i upgraded to Leopard, i have noticed tremendous latency / pinwheel issues in many areas such as:*
    1. Switching between running applications hangs up sometimes as long as 15 seconds
    2. Video playback in quicktime is choppy
    3. Various programs take a tremendous amount of time to open
    4. Opening relatively small illustrator and or photoshop files pinwheels for unusually long time
    5. Opening finder windows unusually slow
    One of the MOST frustrating of all issues:
    6. *Powerbook heats up* rather quickly... gets very hot and the fans have NEVER come on... VERY frustrating, since i would have no problem with noise if it meant better performance...
    *Overall, the entire computer feels VERY sluggish*
    i have tried clean installs, as well as regular maintenance... and upgraded my RAM to the max of 2GB
    Is there anything else i can do? Anyone else having similar problems and or know the best way to repair?
    DESPERATE for a solution here... while i realize the G4 can only handle so much, i just feel like it cant possibly be this slow under leopard... or can it?!
    ANY HELP AT ALL greatly appreciated...
    Best,
    Mike

    6. *Powerbook heats up* rather quickly... gets very hot and the fans have NEVER come on... VERY frustrating, since i would have no problem with noise if it meant better performance...
    Have you run the Apple hardware test? One of the tests is to specifically test the fans.
    *Overall, the entire computer feels VERY sluggish*
    How much free disk space do you have? You need 10% to 15% free for systems usage. Less than that an performance can really slow down.
    If you bring up the activity monitor, under system memory, what does it say for page ins and outs?

  • New to BT, Speed and Stability Issues

    Hiya,
    I've been on BT Unlimited Broadband for just over 2 weeks now. I have a few problems, it seems:
    1. Gigabit port just doesn't seem to work. I've searched this one and I do have a HH3 Type A. It works on the occasional restart, but then stops...
    2. I keep ending up with absolutely unusable speed. I've had speedtest results as low as 0.69 to 0.07 mbps (at this point the BT one won't even work as it's too slow). As soon as I reset my HH everything goes back to 'normal' at 10-12mbps.  This happens once a day on weekends (I'm at home more though) and maybe every couple days during the week.
    3. I'm just generally finding the broadband 'flakey'.  High pings, latency in gaming, sudden lag... I'm not convinced my stats look great and my profile seems to be dropping (at best it was over 16mb, I've seen it down to 10).  Unfortunately I had to reset my router earlier today as the Internet wasn't usable, at that point I'd had about 23 hours of connectivity (not a manual reset) and my HEC and CRC numbers were up to about 15 million... Here's my stats after an hour and a half.  Does this look normal or a cause for concern? I've not got a telephone to do a line test, but I'll see if I can get one in the next day or so if need be.

    To my knowledge I have only a master socket in this flat where the router is connected via a new filter (though it's an old style socket with a BT logo top-left and a solid one-piece faceplace). I've checked wired and wireless, etc with same results.
    Any thoughts or advice would be greatly appreciated.  
    Solved!
    Go to Solution.

    Thank you for your advice.  I did the line test with a corded phone and it seemed OK. No loud crackling or anything, maybe a bit of a faint hum, but nothing noteworthy.  It dawned on me that I hadn't tried swapping out the filter and having done that the speed has gone up and the errors have gone down.
    BT have also agreed to swap out my HomeHub for a Type B to fix the Gigabit issue.
    Could I ask, what do you think of these results now?  The other thing is... it's switched to Interleaved mode from Fast I noticed.  Are there any consequences or anything I need to do since it seems I spent my whole first 10 days using a duff filter?  Will it have any lasting effects on my profile/speed?
    Thank you very much for your assistance.

  • Raid Performance and Rebuild Issues

    Rebuilding a Raid array
    What happens when you have a Raid array and one (or more) disk(s) fail?
    First let's consider the work-flow impact of using a Raid array or not. You may want to refresh your memory about Raids, by reading Adobe Forums: To RAID or not to RAID, that is the... again.
    Sustained transfer rates are a major factor in determining how 'snappy' your editing experience will be when editing multiple tracks. For single track editing most modern disks are fast enough, but when editing complex codecs  like AVCHD, DSLR, RED or EPIC, when using uncompressed or AVC-Intra 100 Mbps codecs, or using multi-cam or multiple tracks  the sustained transfer speed can quickly become a bottleneck and limit the 'snappy' feeling during editing.
    For that reason many use raid arrays to remove that bottleneck from their systems, but this also raises the question:
    What happens when one of more of my disks fail?
    Actually, it is simple. Single disks or single level striped arrays will lose all data. And that means that you have to replace the failed disk and then restore the lost data from a backup before you can continue your editing. This situation can become extremely bothersome if you consider the following scenario:
    At 09:00 you start editing and you finish editing by 17:00 and have a planned backup scheduled at 21:00, like you do every day. At 18:30 one of your disks fails, before your backup has been made. All your work from that day is lost, including your auto-save files, so a complete day of editing is irretrievably lost. You only have the backup from the previous day to restore your data, but that can not be done before you have installed a new disk.
    This kind of scenario is not unheard of and even worse, this usually happens at the most inconvenient time, like on Saturday afternoon before a long weekend and you can only buy a new disk on Tuesday...(sigh).
    That is the reason many opt for a mirrored or parity array, despite the much higher cost (dedicated raid controller, extra disks and lower performance than a striped array). They buy safety, peace-of-mind and a more efficient work-flow.
    Consider the same scenario as above and again one disk fails.  No worry, be happy!! No data lost at all and you could continue editing, making the last changes of the day. Your planned backup will proceed as scheduled and the next morning you can continue editing, after having the failed disk replaced. All your auto-save files are intact as well.
    The chances of two disks failing simultaneously are extremely slim, but if cost is no object and safety is everything, some consider using a raid6 array to cover that eventuality. See the article quoted at the top.
    Rebuilding data after a disk failure
    In the case of a single disk or striped arrays, you have to use your backup to rebuild your data. If the backup is not current, you lose everything you did after your last backup.
    In the case of a mirrored array, the raid controller will write all data on the mirror to the newly installed disk. Consider it a disk copy from the mirror to the new disk. This is a fast way to get back to full speed. No need to get out your (possibly older) backup and restore the data. Since the controller does this in the background, you can continue working on your time-line.
    In the case of parity raids (3/5/6) one has to make a distinction between distributed parity raids (5/6) and dedicated parity raid (3).
    Dedicated parity, raid3
    If a disk fails, the data can be rebuild by reading all remaining disks (all but the failed one) and writing the rebuilt data only to the newly replaced disk. So writing to a single disk is enough to rebuild the array. There are actually two possibilities that can impact the rebuild of a degraded array. If the dedicated parity drive failed, the rebuilding process is a matter of recalculating the parity info (relatively easy) by reading all remaining data and writing the parity to the new dedicated disk. If a data disk failed, then the data need to be rebuild, based on the remaining data and the parity and this is the most time-consuming part of rebuilding a degraded array.
    Distributed parity, raid5 or raid6
    If a disk fails, the data can be rebuild by reading all remaining disks (all but the failed one), rebuilding the data and recalculating the parity information and writing the data and parity information to the failed disk. This is always time-consuming.
    The impact of 'hot-spares' and other considerations
    When an array is protected by a hot spare, if a disk drive in that array fails the hot spare is automatically incorporated into the array and takes over for the failed drive. When an array is not protected by a hot spare, if a disk drive in that array fails, remove and replace the failed disk drive. The controller detects the new disk drive and begins to rebuild the array.
    If you have hot-swappable drive bays, you do not need to shut down the PC, you can simply slide out the failed drive and replace it with a new disk. Remember, when a drive has failed and the raid is running in 'degraded' mode, there is no further protection against data loss, so it is imperative that you replace the failed disk at the earliest moment and rebuild the array to a 'healthy' state.
    Rebuilding a 'degraded' array can be done automatically or manually, depending on the controller in use and often you can set the priority of the rebuilding process higher or lower, depending on the need to continue regular work versus the speed required to repair the array to its 'healthy' status.
    What are the performance gains to be expected from a raid and how long will a rebuild take?
    The  most important column in the table below is the sustained transfer  rate. It is indicative and no guarantee that your raid will achieve  exactly the same results. That depends on the controller, the on-board  cache and the disks in use. The more tracks you use in your editing, the higher the resolution you use, the more complex your codec, the more  you will need a high sustained transfer rate and that means more disks in the array.
    Sidebar: While testing a  new time-line for the PPBM6 benchmark, using a large variety of source  material, including RED and EPIC 4K, 4:2:2 MXF, XDCAM HD and the like,  the required sustained transfer rate for simple playback of a  pre-rendered time-line was already over 300 MB/s, even with 1/4  resolution playback, because of the 4 4 4 4 full quality deBayering of  the 4K material.
    Final thoughts
    With the increasing popularity of file based formats, the importance of backups of your media can not be stressed enough. In the past one always had the original tape if disaster stroke, but no longer. You need regular backups of your media and projects.  With single disks and (R)aid0 you take risks of complete data loss, because of the lack of redundancy.  Backups cost extra disks and extra time to create and restore in case of disk failure.
    The need for backups in case of mirrored raids is far less, since there is complete redundancy. Sure, mirrored raids require double the number of disks but you save on the number of backup disks and you save time to create and restore backups.
    In the case of parity raids, the need for backups is more than with mirrored arrays, but less than with single disks or striped arrays and in the case of 'hot-spares' the need for backups is further reduced. Initially, a parity array may look like a costly endeavor. The raid controller and the number of disks make it expensive, but if you consider what you get, more speed, more storage space, easier administration, less backups required, less time for those backups, continued working in case of a drive failure, even though somewhat sluggish, the cost is often worth more with the peace-of-mind it brings, than continuing with single disks or striped arrays.

    Raid3 is better suited for video editing work, because it is more efficient when using large files, as clips usually are. Raid5 is better suited in high I/O environments, where lots of small files need to be accessed all the time, like news sites, webshops and the like. Raid3 will usually have a better rebuild time than raid5.
    But, and there is always a but, raid3 requires an Areca controller. LSI and other controller brands do not support raid3. And Areca is not exactly cheap...
    Keep in mind that a single disk shows declining performance when the fill rate increases. See the example below:
    A Raid3 or Raid30 will not show that behavior. The performance remains nearly constant even if fill rates go up:
    Note that both charts were created with Samsung Spinpoint F1 disks, an older and slower generation of disks and with an older generation Areca ARC-1680iX-12.

  • Free Jabber connection and stability issues

    I am the video administrator for UTD and free jabber is a foundational block for our video deployment.  About a month ago we began to notice free jabber having issues connecting (signing in) and dropping calls.  Here is a summary of our findings.
    1. About 20% of our calls with free jabber are experiencing issues
    2. Calls that can't sign in recieve an "unable to register" error.
    3. Calls that have problems staying connected have very sparatic connections.  Over an hour long video conference they will stay connected for 20 seconds, then drop, then connect back for 5 minutes, then drop, then connect for 2 seconds, then drop, then connect for 30 minutes, then drop, then connect for 3 minutes, then drop, etc.
    4. Our VCS Expressway shows many different errors for the same call.  A list of the errors are "Interowrked No Permission - Insufficient privilege", "403 Forbidden", "487 Request Teminated", "Undefined reason", "Unknown reason".
    We believe that the "user unable to register" is due to a maxing out of the Cisco VCS Expressway.  We believe the other issues are due to Cisco firewall mishandling the free jabber calls.  There is an open discussion with our sister sites about this issue.  We will be testing/monitoring free jabber connections over the next few weeks.  Sniffing the connection should tell us exactly what side the errors are coming from, but given that none of our other video equipment is having problems nor is our Enterprise Jabber having issues, all hands are pointing to Cisco's free jabber infrastructure not configured correctly and not being able to handle the load.
    Anyone want to comment on this?
    -Brian Moore

    Still seeing disconnects.  But now also testing Ipad jabber video and seeing similar issues there.  Really seems like Cisco's infrastructure can't handle the load.
    Any thoughts?

  • Very Low Performance And Stability gaps

    Hello, first of all, sorry me because of my low level english.
    I have recent bought new pieces for my sistem, my older CPU was a Duron 1300 (overclocked 1400) in a Gigabyte Ga-7zxr mobo with 512 SDRAM 133 mem.
    I choosed a MSI mobo, the KT6 delta (sr), a 2600 XP+ and 512 DDR 333, with no knowed fabricant.
    I get a lower performance in my new system than the older, isn't normal.
    I have so much questions, please reply me so much you can, i'm getting crazy
    I've read in other posts some specifications about Amp' consume in the mobo.
    Where can i see it? Say me and i'll post it.
    My 2600 xp+ is the model 8 (not the actual 10), it have 256 Kb cache instead 512 and run over 200 mhz over the model 10.  167 x 12.5.
    (wrong forum?, could be, dont reply me to it if you think i should no make this question)
    Well, go with mobo problems.
    My monitor refresh (like if I change the resolution) so often, I don't know why.
    In the dxdiag, in the 3D test, i get a cube no well showing, i only see a bad image, like if the cube is turning hyper velocity.
    In all sandra test i have a performance according with my system, but when i get to ride games, i get low performance than in my older system
    My mem isn't kingston and isn't of any knowed mark. I only could to get kingstom memory instead, i would do it? is really so recomended?
    Well, my best crazy head is about configuring the bios.  I don't know what to put in this values:
    System Bios Cacheable: Enabled.
    C000, 32k Shadow: Enabled.
    SDRAM frequency Auto
    SDRAM CAS# latency
    Row precharge Time
    Ras Pulse Width
    Ras To CAS delay
    Write recovery cycle
    Sdram Burst Length: 4qw
    SDRAM 1T Command: Enabled
    Fast Command Turbo
    FAST R"R turnaround Enabled
    about AGP:
    AGP Master 1 WS Write
    AGP Master 1 WS Read
    AGP READ Synchronization
    PCI LAtency  Timer 32
    Frecuency..
    Spread Spectrum = 0.5%
    CPU FSB 166
    CPU RATIO Auto
    CPU CORE Auto
    Vlink Voltage Auto
    DDr Voltage Auto
    AGP Voltage Auto
    Too much question, really, i know.
    I'm thinking to install a CPU Cooler in the mobo chipset and in the RADEON chipset also, must i do it?
    All my CPU details are below.
    Thanks for all.!!!!

    The model 8 Of AMD AThlon XP is a 333 FPU. I've read it in AMD and other pages.
    i've reduced the case temp by putting another coller in this, but it makes really noise. The new Case temp is 48º C. I'm thinking about to buy another case, with some coolers.
    May i have to change the mem to a kingstom mem?
    Much thks.

  • I thought Apple fixed FCP X performance and stability...!

    Though I was experiencing this with 10.0, it seems to still be the case with 10.0.1!
    Whenever I'm rendering, exporting or optimzing media in FCP X, I'm unable to open or work in any other application. Even attempting to open something as simple as Safari has proven to be a task... The dreaded beach ball spins and I find myself force quitting the apps.
    Anyone else experiencing this?
    I'm working on:
    Early 2011 17" MacBookPro
    Intel Quad Core i7 2.3 GHz Processor
    8 GB RAM
    Oh by the way, here is a snapshot of my CPU and memory while export from FCP X.

    Interesting, I'm now transcoding using compressor.
    Here is a snapshot of my CPU & Memory usage:
    I can comfortably open and work with most apps, however as soon as I open FCP X, THE BEACH BALL APPEARS......!
    This is so annoying.

  • Performance and Graphical Issues with iOS 4.3 and IPod Touch 4th Generation

    My Ipod touch is only a week old and I just updated it to iOS 4.3 from the original firmware, but after I updated the device it seemed to start generating white lines in the status bar area unexpectedly. Then at the same time my device would stop responding for a couple of seconds or become extremely slow. I also notice that my album art is misplaced and/or obscured and nothing is misplaced on iTunes. I've restored it two to three times. The device can not be downgraded so I'm not sure what to do.

    Hmmmm... you know what... some of my album art was misplaced also... mainly for my "Unknown Artists" but still... Oh yeah and everyone knows about the glitch on the top bar, theres a post with about 20,000 views on it so maybe you should check there

  • Performance / stability issues with BDB 3.3.62 while checkpointing

    Hi,
    first of all: we use BDB 3.2 for more than a year within our application and we never had any performance or stability issues. Now we are about to release a new version of our software with BDB 3.3 and we found some problems during our release tests.
    This is the situation: we have implemented some cleanup routines that make very heavy use of the BDB environment. The common usage pattern is to scan the database (about 300GB with >> 100 million items) and than delete a lot of items from the database. The first versions of our cleanup routine worked without any problem but during performance tuning of our code we suddenly and reproducible encountered segmentation faults in the com.sleepycat.je.recovery.Checkpointer thread. We analysed more that 10 VM crashes and ALL crashes were related to Checkpointer thread. (Linux 64 bit, JDK 1.5.0_013 / 1.6.0_06)
    After we removed our performance tuning (only application logic – nothing BDB-related) the VM crashes disappeared – so it looks like some kind of problem which only occurs under high load conditions. Next thing we tried was enabling our performance tuning and setting Ceckpointer configuration to default (write a checkpoint after 20MB) before that we used time based checkpointing with 60 sec interval.
    With Default Checkpointer configuration there were no VM-crashes but performance was very slow!
    Finally my question: What Checkpointer configuration would you recommend for an environment that is under very high load with regard to delete operations? Would you recommend using “high priority Checkpointing”? Would you recommend time- or data-based checkpointing?
    It looks like Checkpointing every 60 seconds was not a good idea but 20MB seems to be too slow.
    This leads to another question: What does a longer Checkpointing interval mean for recovery time? Does recovery take substantially longer if checkpointing is done less fequently?
    Any help would be very much apprechiated.
    Here are two HS_ERR_PID

  • Stability issues, playback stutters, and occasional crashes with 8.1 update

    Hi all, I'm having a bunch of weird stability issues with Premiere CC 8.1 on Mac OSX Mavericks 10.9.5. I'm working on a medium sized 1080p project with about 60-80 pieces of media totaling about 60GB. Footage was from a DSLR and was transcoded into prores 422 for editing.
    Initially after updating to 8.1 and creating my project I didn't notice any issues but after progressing further in the edit and adding additional video tracks, titles, and a couple small AE comps I've noticed a pretty drastic falloff in performance. I will get occasional crashes and playback is slow to respond. After pressing spacebar or L it'll hang for anywhere from a few seconds to a minute before actually playing back. During playback it'll get caught up and hang and I have to stop playback and wait a bit for things to return to normal. I'm also experiencing performance issues scrubbing through footage in my project bins.
    I've tried some basic troubleshooting like cache clearing, preference trashing, video driver updating, and un- and reinstalling to no avail. It'll sometimes work ok but usually displays most of the above issues. I've been using premiere for a bit over a year now and haven't experienced any of these issues on my other older machines, let alone my new MBP. Premiere is usually very snappy and misbehaves rarely.
    Technical bits:
    Premiere CC (2014) v8.1
    15" Retina MacBook Pro
    Mac OSX Mavericks 10.9.5
    2.6 GHz Intel Core i7
    16 GB 1600 MHz DDR3
    NVIDIA GeForce GT 750M 2048 MB
    1TB Apple SSD

    Hi Ian,
    Is it possible to reinstall your GPU drivers? I have heard that this might be at the heart of this issue. Also, trash preferences. Here is the full list I'm asking Mac folks to try.
    Sign out from Creative Cloud, restart Premiere Pro, then sign in
    Update any GPU drivers
    Trash preferences
    Ensure Adobe preference files are set to read/write
    Delete media cache
    Remove plug-ins
    Repair permissions
    In Sequence Settings > Video Previews, change the codec to one that matches your footage
    Disconnect any third party hardware
    Reboot
    Report back if anything here worked for you.
    Thanks,
    Kevin
