Slow System Performance after binding Machine to OD

Hello,
I've recently installed Leopard Server using standard configuration. I bound two machines to test and I noticed immediately that I took a performance hit speed wise just doing regular stuff like opening applications and browsing internet takes longer than usual for some reason now they use to pop instantly prior to binding to Server. So I broke the connection to see if the server was causing the lag but both machines for some reason now continue to lag. Does the server alter the client in some way that affects its performance? and why does it still affect the machine after the connection is broke? Any input is appreciated.

Just binding a client to an OD server shouldn't make any noticeable difference in speed, assuming that the network is set up correctly. Network homes certainly will slow you down compared to local homes.

Stuck at Optimizing System Performance after installing Security Patch

24" iMac seems to be stuck at "Optimizing System Performance" after installing the latest Security Update. Software Update won't quit. Nervous to force the computer to shutdown during that process. It's working fine at the moment other than that the Software Update box won't go away.
What do you think?

Well kind of answered my own question. Tried to run Activity Monitor which only started halfway and then crashed. I remembered the whole computer is backed up to an external drive everyday so I figured if it won't start at least I can start up from the external drive.
Forced the shutdown by holding the power button. Started up w/o a hiccup; ran Repair Permissions which checked out and the Verify the Disk with First Aid which also checked out fine.
So I guess it's ok though I may unplug that external for a day or two.

Slow system performance...

Hey guys, i recently installed Arch Linux via my 0.7.2 CD. I then did a full system upgrade, up to the 2.6.19 kernel, boots fine, followed the new kernel instructions.. however it just seems like my overall system performance is SLOOWW. Keep in mind, i have installed Arch on this computer when 0.7.2 first came out, and it ran perfectly fine, everything ran fast. However now since i did a fresh install, upgraded to the latest, things seem slow.
i have installed xorg as well as gnome, including the nvidia drivers. When ever i type startx, it takes more then a few seconds for anything to happen after the command has been entered, before it would be VERY snappy. Gnome seems to take longer to load as well. When i launch xterm from within gnome, it takes a while for the xterm window to show, this includes any other windows. When i move windows around overtop of firefox, it seems alot of ghosting is happening, alot of trailling over the desktop when the window is being dragged overtop another window. I checked to see if Nvidia drivers are being loaded which they are. a glxtest reports back a 1500fps + as well as showing nvidia corporation in the glxinfo....
This is a fresh BASE install, upgraded to the current, then Xorg and gnome installed. Top shows no high cpu spikes and i cant figure out why suddenly, application loading seems to be slow...
P.S also, with all of this, accessing webpages seem very slow as well....this includes Pinging an IP address...

well, i added that in, startx as well as gnome + application seem to load as they should now, if that was the reason thanks for telling me about that.
However my internet is still very very slow. Booting into Windows XP i can confirm its not my internet connection, no lag in XP, however in Arch, seems very slow. If its any help, im using the sundance driver
actually, now that applications seem to be loading as they should, my internet connection probebly can be asked in the network section?

Poor System performance after EHP4 upgrade

Hello Experts,
We have just finished our Upgrade to EHP4 for ECC6 system. After the upgrade we are noticing awfully slow system response time.
My SGEN is currently executing and it's showing another 45 hours before it is finished. Are there specific post Upgrade activities that I am missing? Once I try to perform some action it takes ages to compile the program. I undesratand that since SGEN is not run yet so it will need some time to compile and generate load for the application but still the response is takinng agaes before I see the actual Application/Program active in GUI.
Please suggest what I can do to boost up my system performance.
Thanks,
M

Hi Sunny,
Another Update
I looked at SAP Note 146289 - Parameter Recommendations for 64-Bit SAP Kernel
Following is the recommnedation:
Implement the SAP profile parameters as follows:
em/initial_size_MB 1024 up to 1TB (note 835474)
em/blocksize_KB 2048, 4096 or 8192 (note 835474)
ztta/roll_first 1
ztta/roll_area 6500000
The deafult value of the following parameters is 2000000000 (2GB).
They can be changed depending on the HW (RAM) and the configured
SWAP Space:
ztta/roll_extension 2000000000 (2GB)
abap/heap_area_dia 2000000000 (2GB)
abap/heap_area_nondia 2000000000 (2GB)

Continued SLOW online performance after two Archive & Installs

Hi.
I have been living with slow online performance – pages slow to load, movies very slow to load, movies don't play back smoothly, constant buffering – for some 3-4 months before trying to do something about it... (this timeline coincides with a potential Security Update 2008-006 issue discussed here: http://discussions.apple.com/thread.jspa?threadID=1730909&tstart=0 , but I don't have enough savvy to know if that's the problem.)
Equivalent slow performance in both Safari and Firefox... I've compared the same sites I visit on other peoples workstations, PC and Mac, various ISPs – all of their pages and movies light up and play instantly.
Tried to research and do as much as I could before coming here, but I don't have great diagnostic skills... here's what I've got so far:
By late November, I managed to eliminate the ISP (Earthlink) as a cause of the problem... however, due to their direction to change DNS numbers, I can no longer automatically connect online upon booting, but must repeatedly connect via Internet Connect (separate issue?)... via these forums, I've reset the DNS to 208.67.220.220, 208.67.222.222.
Neither hard drive is even half full.
I did an initial Disk and Permissions Repair prior to first A&I... they needed repair then, but subsequent verifications check out clean.
After the first A&I (using the original OS X 10.4 install disk), I downloaded a complete full 10.4.11 update, including all current Security Updates... performance wound up much the same as before.
After the second A&I, and before any updating, I tested online performance – still slow... this time I downloaded only the Mac OS X 10.4.11 Combined Update from November 07, looking to avoid the 2008-006 Security Update... general browsing speed is slightly improved, but any site with a movie or rich graphics behaves like dial-up, as before... Mail is just ok – not fast, but not problematic.
Otherwise, the Mac works well enough, but it's never been a real speed-burner, imo... mainstream graphics apps (Adobe CS2, Quark 6)... the only atypical thing I might have is a Wacom graphics tablet (Intuos 3), but it's always worked fine... no games or brand-X playtime software.
The only other thing I'd be suspicious of is Network Settings, after getting the runaround at Earthlink... but the fact that I can get online at all might rule that out.
I've been at this for days, and am out of ideas... little help?
Thanx.

OK, network settings is the scary stuff that I DO NOT understand...

Make a New location in Network>Location>New, try it without PPoE, just Using DHCP under the TCP/IP tab>IPv4 setting. You can always switch back if it doesn't work.
I found the PPPoE subpane.
Made the New location, it seemed to work briefly, then didn't, then I fumbled my way back to prior settings... I'm willing to try it again, BUT...
What scared me was that after setting New Location, the browser window opened to something called *Internet Configurator*, never seen this before... it asked for my email and password... is this normal?... I've got major privacy and security concerns and DO NOT want to put that password out there if I don't have to.
Please advise before I do this... thanks.

Slow CS3 / system performance after Snow Leopard install

Since installing 10.6, I've noticed a systemwide slower performance; there's a slight hesitation after everything I do. Even something as simple as changing a filename causes a second or two of hesitation... then it lets me change the name.
This is especially noticeable in CS3 software; painting or editing in Photoshop is very difficult, because there's a second or two of hesitation before things occur. Even clicking menu items takes a second before the item opens.
Anyone else have this? So far, 10.6 (and yes, 10.6.1) have been a definite downgrade to my performance.

I have noticed no hesitation or slowdown, in fact startup and shutdown are noticeably faster, and system wide speed is same or better.
This is only relevant for photoshop, but ...

Slow System Performance on SunOS 5.10

Dear all,
Our system experienced very slow response time a few days ago. After checking the wp trace file, we found the oracle is out of memory and there were some malloc failed(not enough space). Our system is ECC6 SR3 SP 16 and Oracle 10g dbase with RAM 4GB and swap 16 GB on container of SunOS 5.10.
My assumption when the process running out of memory, it should retrieve from virtual memory. At command vmstat -s the output of swap in/out and pages swapped in/out is zero. Guess problem with vm of container. Anyone can help? Thanks.

New Install Works Fine then System Crashes After Time Machine Backup

I have installed Snow Leopard and everything went fine. I setup my external drive as the backup drive for Time Machine and did a backup. Then when I next used it, various applications started crashing. Then the System began crashing and gave me the gray screen restart and would never load again.
I got out the Snow Leopard disk and used DIsk Utilities to repair the disk and permissions, which seemed to work well. The computer worked great for a while. Then after I used Time Machine to back it up, when I next used it the System began crashing again.
What is going on here? It seems to be too much of a coincidence that the problems started immediately after I performed my first Time Machine backup to an external drive.

Woodwyn wrote:
Actually I already did that more or less. I re-installed the Snow Leopard printer drivers from the DVD after I previously repaired my system using DIsk Utilities. After which, I was prompted to download and install the 10.6.2 Combo update again. Which I did. After which, I ran disk utility and repaired and permissions verified the disk. But if you think going back to the original 6.0 install is important, then I presume you also mean I need to run all the subsequent updates as well?
So you only re-insalled printer drivers and updated the existing OS to 10.6.2? Then that may be enough. Otherwise, if the issue returns, I would suggest a full re-install of the OS at 10.6.0 followed by updates to 10.6.2.
However, first I am going to repair the drive and NOT enable Time Machine or perform a back-up, to see how long it lasts without crashing. The last two times, the crashing began within an hour of finishing the install and repairing the disk (immediately following a "co-incidental" Time Machine backup both times, of course). It's entirely possible Time Machine is not the culprit, however, that will confirm whether it has been the trigger.
Good troubleshooting strategy. Only time will tell.
Another thought occurs to me...Is the RAM that is installed on your Mac the original cards supplied by Apple - or did you upgrade it with 3rd party RAM yourself. The crashing you described earlier could very well be from a bad RAM card - even one that came from Apple.
It is one 2GB card, or two 1GB cards? If the crashing continues, I would suggest taking one of them out and seeing how things perform, then switching them and seeing if things change.

SLOW report performance with bind variable

Environment: 11.1.0.7.2, Apex 4.01.
I've got a simplified report page where the report runs slowly compared to running the same query in sqldeveloper. The report region is based on a pl/sql function returning a query. If I use a bind variable in the query inside apex it takes 13 seconds to run, and if I hard code a string it takes only a few hundredths of a second. The query returns one row from a table which has 1.6 million rows. Statistics are up-to-date and the columns in the joins and where clause are indexed.
I've run traces using p_trace=YES from Apex for both the bind variable and hard coded strings. They are below.
The sqldeveloper explain plan is identical to the bind variable plan from the trace, yet the query runs in 0.0x seconds in sqldeveloper.
What is it about bind variable syntax in Apex that is causing the bad execution plan? Apex Bug? 11g bug? Ideas?
tkprof output from Apex trace with bind variable is below...

Patrick, interesting insight. Thank you.
The optimizer must be peeking at my bind variables with it's eyes closed. I'm the only one testing and I've never passed %anything as a bind value. :)
Here's what I've learned since my last post:
I don't think that sqldeveloper is actually using the explain plan it says it is. When I run explain plan in sqldeveloper (with a bind variable) it shows me the exact same plan as Apex with a bind variable. However, when I run autotrace in sqldeveloper, it takes a path that matches the hard coded values, and returns results in half a second. That autotrace run is consistent with actually running the query outside of autotrace. So, I think either sqldeveloper isn't really using bind variables, OR it is using them in some other way that Apex does not, or maybe optimizer peeking works in sqldeveloper?
Using optimizer hints to tweak the plan helps. I've tried both /*+ FIRST_ROWS */ and /*+ index(ps pk_persons) */ and both drop the query to about a second. However, I'm loath to use hints because of the very dynamic nature of the query (and Tom Kyte doesn't like them either). The hints may end up hurting other variations on the query.
I also tested the query by wrapping it in a select count(1) from ([long query]) and testing the performance in sqldeveloper and in Apex. The performance in that case is identical with both bind variables and hard coded variables for both Apex and SqlDeveloper. That to me was very interesting and I went so far as to set up two bind variable report regions on the same page. One region wrapped the long query with select count(1) from (...) and the other didn't. The wrapped query ran in 0.01 seconds, the unwrapped took 15ish seconds with no other optimizations. Very strange.
To get performance up to acceptable levels I have changed my function returning query to:
1) Set the equality operator to "=" for values without wildcards and "like" for user input with wildcards. This makes a HUGE difference IF no wildcard is used.
2) Insert a /*+ FIRST_ROWS */ hint when users chose the column that requires the sub-query. This obviously changes the optimizer's plan and improves query speed from 15 seconds to 1.5 seconds even with wildcards.
I will NOT be hard coding any user supplied values in the query string. As you can probably tell by the query, this is an application where sql injection would be very bad.
Jeff, regarding your question about "like '%' || :P71_SEARCH_SOURCE1 || '%'". I've found that putting wildcards around values, particularly at the beginning will negate any indexing on the column in question and slows performance even more.
I'm still left wondering if there isn't something in Apex that is breaking the optimizer "peeking" that Patrick describes. Perhaps something in the way it switches contexts from apex_public_user to the workspace schema?

MacBook Pro 13 " going slower in performance after Installing LION OSX

Hey Guys ,
I had noticed some problems in my MacBook Pro 13" which I bought in the MID of 2011 ( i5 processor ) , I had purchased and installed LION OSX and observed after installing that my Backlite ( Keyboard ) dont get on when I start up at the LOG IN , which used to work in SNOW LEOPARD .
Booting takes SO SO SO long as when comapared with the previous OS .
Heating Problem is also a must to mention .
If you guys know how to reduce these problems please help me out !
Thank You .

I'm curious if you ever found a solution for this issue. I recently purchased the SanDisk Extreme II 480GB, replacing my OWC Extreme Pro 240GB. The OWC never experienced the "slow to wake" issue whereas the SanDisk drive does, consistently. To make sure I'm having the same symptoms, this is what happens to me: Put the mac to sleep (either manually or letting it do it on its own, waiting for the led to pulse showing that it is asleep), then wake it up (press a key on the keyboard), the logon screen shows almost immediately but as soon as I try to type the pinwheel/beach ball shows up, I wait between 20 and 30 seconds and then I'm able to type and all is well.
I contataced SanDisk and their support was horrible. They simply told me "contact MAC for this issue" (no joke, not "contact Apple" but "contact MAC", in all caps). I explained that it works fine with the OWC drive just not the SanDisk. They replied with another article showing that all macs have trouble waking from sleep (not true). I replied again indicating that I've never had this issue with any of my 3rd party drives, only this SanDisk. Then the replied simply stating that all mac's have issues with 3rd party hard drives when waking from sleep. At this point I threw a fit and yelled at my screen, even though it wasn't my screens fault.
In any case, their support has not been willing to do any actual troubleshooting. I'd love to return it and I might have to - but as you stated, it's annoying to have this issue but the performance is fine the rest of the time.
Thanks for any input you have.

Very slow (glacial) performance after 10.4.10 update

Updated Mac mini 1.66GHz last night via Software Update. Initially got extremely slow reboot and finder performance. Tried many things ie safe boot, repair permissions, reset pram, and even reinstall via Combo Update but all to no avail. It has been taking over 5 minutes to just boot up to Finder. Finder operations are really slow, but application response is nearly as fast as pre-update.
So, I do a backup (just in case) and plan to go back to 10.4.9. I normally backup weekly to an extra internal drive in my G5 Dual 2.0 via wireless and usually takes about 30 to 45 min. However, this backup takes over 18 hours!
I have perused these forums and others, but have not noticed this slow issue occurring. Any hints on how to speed back up?

Hello janala:
You might try trashing the preference file (com.apple.finder.plist) and restarting. Also, I would certainly run repair disk from your software install DVD.

Macbook Pro has slow start up after Time Machine restore

My 2.4 Ghz Santa Rosa MBP had Ubuntu Hardy and 10.5 on it. I played with Ubuntu for a while and decided to go back to OS X only. I wiped the HDD and reinstalled Leopard, then restored from a time machine back-up. Since then, my MBP has gone to a white blank screen for about 5 or 6 seconds before displaying an apple on start up. What could be causing this? I tried disk utility options, nothing worked, restored from a different back- up with no luck also. Any Ideas? My start up has slowed a very noticeable amount since going back to one OS
Thanks in Advance

Slow system boot after tweaks

yesterday I founded article on wiki about optimizations that can make my arch boot faster. So I:
disabled some of unused tty
added flags to menu.lst
disabled autoload modules in rc.conf and make load only those which were listed by hwdetect
changed mkinitcpio hooks
https://wiki.archlinux.org/index.php/Speed_Up_udev Option 3
but now I'm a little dissapointed because when arch is booting and process comes to Loading Modules it takes much much longer than whole booting process before "optimizations". How to solve it?

The only thing on your list that's not likely to cause these kind of complications is no. 1 - disabling unused ttys.
I would first enable module autoloading again. If the system still boots slowly after that, you can cross the module section off your list.
In that case I'd move on to the symbolic link you made for udev (option 3). Is the symlink really accurate?
If so, move on to the mkinitcpio hooks. They really shouldn't be tempered with. But just in case, this is all you need for a system with root on an ahci device using filesystem ext4:
MODULES="ahci sd_mod ext4
HOOKS="base"
It is safer to use the default though
HOOKS="base udev autodetect pata scsi sata filesystems"
If restoring the default mkinitcpio doesn't help there's only one point left on your list. Delete the kernel boot parameters.
There's also a bug in 2.6.39 related to modules ee-prom where the system would hang @ loading modules but that seems unlikely here.
P.S.:
Also, do a system update. There's a new version of udev that might or might not fix your issue.

Very slow print performance after installing Photoshop CC

Hello-
A colleague of mine has been using Photoshop CS2 forever. I finally convinced her to upgrade to a newer version, and we installed Photoshop CC on her Win 7 Pro desktop.
She is trying to print today, and jobs that would take no time at all in CS2 are taking exorbitant amounts of time when sent from CC. For example, we open a PSD in CS2 that is 15MB. We choose "Print with preview" and then send 25 jobs to the printer. From hitting the button to the last item coming out of the printer, we're done in less than 2 minutes.
If we open the same file from CC and print, it's taking about 1 minute per copy, or about 25 minutes in total.
The problem seems to be with Photoshop sending the job to the printer, as we can see the jobs increment in the printer display at wildly different rates depending on which version we print from.
The same problem appears with pretty much any PSD or TIF. If we conver the file to PDF from CC and then print from a PDF application (not CC), print speeds fly again.
Any ideas on where I should start troubleshooting? (As an aside, the GPU on her computer isn't particularly good, but I would hope that the print engine doesn't require it.)
Thank you in advance.

The problem seems to be with Photoshop sending the job to the printer...
The very first thing I would do is hit the website for the printer manufacturer and make sure you have the latest print drivers. Second thing is go to preferences and make sure Photoshop has enough RAM assigned and decent space on the scratch disk. Putting the scratch on an SSD or different drive helps a lot. But the RAM is the main thing. You didn't mention the PC/Mac or RAM, I would assume you have at least 16GB and at a very minimum, 8GB on that machine. Then allocate 75% of the RAM to Photoshop. Hope that helps!

Slower system reboot after installed CC Apps. Why?

I have a 2011 thunderbolt 17 inch macbook pro with an SSD HD and 8 gigs of ram installed. When I installed my SSD, my computer would complete a restart cycle in 20 seconds. But after I installed the CC apps my computer reboots in about 40-45 seconds now. Im sure it is the CC apps that are causing this additional boot time because I did a clean install of my OS 10.8 and did my reboot before I installed the apps and it was back to its 20 second reboot. Once I reinstalled the CC Apps it was at 40 secs again. Does anyone know why the CC apps cause this additional time to my reboot? Im just curious?

Hi AzzieScott,
No sure, but things I wondered about - how long does a restart take if you started the mac in safe boot. Does ending any Adobe processes with Activity Monitor prior to the restart make it take 20 seconds again?
