PS CS6 Slow NAS Access

Hi,
I am running Photoshop CS6 (13.0.1) on my 2013 MacBook Pro (i5 8GB RAM, OSX 10.8.5) with Bridge CS6 as my main way to browse my CR2 files. I access my images on a Seagate GoFlex Home NAS, which is connected to a Netgear GS108P gigabit switch. All devices are cabled, using cat5 cabling. The issue I'm getting is as soon as I am finished working on the image and go to save the file, things slow down dramatically. My LAN connection suddenly goes from Rx & Tx in tens of megabytes to 20KB/sec, which is painful! Any ideas?
Cheers
Mark

Hi Mark,
unfortunately I could never fix the problem, but I can tell you that after getting rid of the Buffalo NAS and buying a Synology DS213Air things now improved a lot. To begin with I can now access the NAS via afp:// instead of smb:// only (the Buffalo NAS said it would support AFP protocol but it never worked). Browsing folders is now reasonably fast, still it is faster with Windows (running on the same mac machine, which really p*sses me off)

It's very slow to access file server after installed SP1 of Win7.

I found it's become very slow to access shared files on file server after installed win7 SP1, (windows6.1-KB976932-X86.exe), access same file, the win7 without sp1 is fast in 5 secs, but the pc with sp1 need more than 30 secs. And
I tried to removed the sp1, everything goes fine, access fast as others.
I don't understand what's the reason and which feature affected it, I believe the sp1 can help Win7 be more safety, but why the performance on it get worse.
And I didn't find the same question or tips on forum or website, do you really haven't the issue?

Slow database access across network

I have a postgresql database setup on a server machine and have written a java program in netbeans that accesses it. The problem i have is that running the jar created by netbeans from any other machine on the network has really slow database access but running the program from netbeans itself is fine. Running the jar on the server machine is also fine.
Anyoner got any idea as to why this could be?

I don't know if this will help, I'm just wading into writing my own java apps to hit a SQL 2K db. We purchased a SQL2k/JSP driven backend on which we extended their OM to meet our needs. It was build as an extranet product but ran very poorly across the 'Net.
The biggest annoyance was not the actual transaction time of the app but the time it took from the end user to click a button and the start of the transaction.
After much testing I determined it was the JSP.
So what we have done to alieviate the issue is to have multiple regional Tomcats that 'throw' their transactions to a central colocation where the SQL servers sit (so the tomcats do the JSP managment in a sense locally to the end user) . For big clients we actually place a linux/tomcat box at the edge of their firewall. For whatever reason, I'm far too busy to determine the how now that I get the responses I need, this has completely eradicated the annoying pause between user interaction and the actual transaction to the DB server. Extended testing showed the SQL server running in the sub half second range to process a command but the tomcat rendering could take up to 2 to 5 seconds in worst case for no discernable reason. Moving the tomcat frontends to the network segment where the clients we solved it.
Of course I'm digging into swing now too and it has some slowness that the Eclipse zealots say SWT fixes but I haven't the depth or experience to properly judge the camps arguments yet.

Adobe CS6 slow down

Here's my specs:
OSX 10.8.5
Pr6 6.0.5
Imac 3.4 i7
24GB ram
Plenty of space on my Mac HD
Media on a usb3 drive.
Recently installed the trial of CC
All of a sudden CS6 slows down and I get the beach ball when performing certain processes such as:
Duplicating a sequence
Renaming a bin
Dropping a merged clip into the project window.
It's really weird, it plays back my RED footage fine but when I do certain tasks
as I listed above, it beach balls and I can't work.
In the activity monitor I see that Premiere process hits over %100 cpu, when I do these processes.
Any idea how to fix this? I tried restarting, tried disbeling cuda and doing software only.
This just started happening and is a major time sink.

Seems to just be affecting that one project file.
When I open a different project file, things work okay. When I create a new project file on the same media drive, things are okay (I often work off externals for clients so I keep everything on th drive).
Anybody have an idea what's going on? I am working with 5k RED files but the playback isn't the problem, it's those weird issues above.

Very very slow file access iSCSI NSS on SLES11/XEN/OES11

Hi,
Like many Novell customers while carrying out a hardware refresh we are moving off traditional Netware 6.5 to OES11 and at the same time virtualising our environment.
We have new Dell Poweredge 620 serves attached by 10gig iSCSI to Equalogic SAN
Installed SLES will all patches and updates and XEN and then created OES11 SP2 virtual machines, these connect to NSS volume by iSCSI
Migrated files from traditional netware server to new hardware and stated testing and ran into very very slow files access times
A 3.5mb pdf file takes close to 10 minutes to open from local PC with Novell Client installed, same if no client and open via cifs. Opening same file off traditional NW6.5 server takes 3-4 seconds.
We have had a case open with Novell for almost 2 months but they are unable to resolve.
To test other options we installed VMWare ESXi on the internal usb flash drive and booted off that, created same OES11 VM and connected to NSS on SAN and same pdf open in seconds.
The current stack of SLES11/XEN/OES11 is not able to be put into production
Any ideas where the bottleneck might be? We think is in XEN.
Thanks

Hi,
As also mentioned in the SUSE forums, there is the option of using the Equallogic Hit Kit. One of the tools, next to the great autoconfigure options it has, is the eqltune tool.
Some of the stuff that I've found important:
-gro is known read performance killer. Switch if off on the iSCSI interfaces.
- if possible (meaning you have decent hardware), disable flowcontrol as this generally offers stability but at the cost of performance. If your hardware is decent, this form of traffic control should not be needed.
-To have multipath work correctly over iSCSI and starting SLES 11 SP1. Make sure kernel routing and arp handling are set correctly (not directly relevant if you only have 1 10 GB link):
net.ipv4.conf.[iSCSI interfaceX name].arp_ignore = 1
net.ipv4.conf.[iSCSI interfaceX name].arp_announce = 2
net.ipv4.conf.[iSCSI interfaceX name].rp_filter = 2
Test if traffic is actively routed over both iSCSI interfaces:
ping -I [iSCSI interfaceX name] [iSCSI Group IP EQL]
-Make sure network buffers etc are adequately set as recommended by Dell (set in /etc/sysctl.conf):
#NetEyes Increase network buffer sizes for iSCSI
net.core.rmem_max = 16777216
net.core.wmem_max = 16777216
net.ipv4.tcp_rmem = 8192 87380 16777216
net.ipv4.tcp_wmem = 4096 65536 16777216
net.core.wmem_default = 262144
net.core.rmem_default = 262144
-Settings for the /etc/iscsi/iscsid.conf I'm using:
node.startup = automatic # <--- review and set according to environment
node.session.timeo.replacement_timeout = 60
node.conn[0].timeo.login_timeout = 15
node.conn[0].timeo.logout_timeout = 15
node.conn[0].timeo.noop_out_interval = 5
node.conn[0].timeo.noop_out_timeout = 5
node.session.err_timeo.abort_timeout = 15
node.session.err_timeo.lu_reset_timeout = 20 #Default is 30
node.session.err_timeo.tgt_reset_timeout=20 #Default is 30
node.session.initial_login_retry_max = 12 # Default is 4
node.session.cmds_max = 1024 #< --- Default is 128
node.session.queue_depth = 128 #< --- Default is 32
node.session.iscsi.InitialR2T = No
node.session.iscsi.ImmediateData = Yes
node.session.iscsi.FirstBurstLength = 262144
node.session.iscsi.MaxBurstLength = 16776192
node.conn[0].iscsi.MaxRecvDataSegmentLength = 131072 #A lower value improves latency at the cost of higher IO throughput
discovery.sendtargets.iscsi.MaxRecvDataSegmentLeng th = 32768
node.session.iscsi.FastAbort = No # < --- default is Yes
-Have Jumbo frames configured on the iSCSI interfaces & iSCSI switch.
If you are using multipathd instead of the dm-switch provided with the Equallogic Hit kit, make sure the /etc/multipath.conf holds the optimal settings for the Equallogic arrays.
Ever since Xen with SLES 11 SP1 we have been seeing strong performing virtual servers. We still use 1GB connections (two 1GB connections for each server, serving upto 180~190Mb/s).
There could be a difference with the 10GB setup, where multipath is not really needed or used (depending on the scale of your setup). One important thing is that the iSCSI switches are doing their thing correctly. But seeing you've already found better results tuning network parameters on the Xen host, seems to indicate that's ok.

Why performance of Illustrator CS6 slower than Illustrator CS5.5?

Ex: Process get text of TextFrame has 657 characters:
Dim t1 As String
Dim t2 As String
t1 = DateTime.Now.Minute & " " & DateTime.Now.Second & " " & DateTime.Now.Millisecond
Dim text As String
For iChar = 1 To iCharNum
      oChar = oContents.Characters(iChar)
      Dim str As String
      str = oChar.contents.ToString
      text = text & str
Next
t2 = DateTime.Now.Minute & " " & DateTime.Now.Second & " " & DateTime.Now.Millisecond
Result:
Time of CS5.5: 0s 487
                         t1= 38 43 71
                         t2= 38 43 558
Time of CS6: 3s 871

Slow internet access after Mavericks upgrade

I have been experiencing very slow internet access since I upgraded to Maverics OS.
The Wifi connection is unstable. Sometimes it looses connection. I did not have this problem before.
Is this a problem experienced by others? Do you have any steps on how you got this resolved?

what is the model of your wireless adapter?

Why is CS6 slow, 64bit-mode or not?

Got the CS6 trial for OSX. Its not nearly as responsive as promised.
It can't handle average files with let say 30states in it.
Escpecially if you create symbols with a lot of elements(30+) which are nested and you want to edit those symbols, there is huge perfomance drop:
You can't use your keyboard for moving elements within those symbols. The programs give you no feedback what it is doing.
Then I checked the activity monitor: Apparently fireworks is not running in 64bit mode.
Is this just the trial version or is the Adobe-Add misleading that it should be running in 64bit?
My comp-specs:
lates iMac
20GB Ram
SSD

And why it has not been improved? Its so obvious slow!

Performance improvement in CS6 is made interms of refreshing the Property inspector on Mac platform.
On Windows platform file open /edit and save limit has been increased for 64 bit machines.
Adobe Fireworks CS6 is a 32-bit application only.Also performance interms of rendering on canvas or preview is not changed in CS6.

Extremely slow data access on auto detected NAS drive

I have a 27 inch iMac connected to a home network, on which I recently installed a Seagate Central NAS drive. When Finder automatically finds the drive under Shared, it wants to automatically log me into the drive as "Guest" instead of the administrator user I created on the Seagate drive. As Guest, the access time is extremely slow (takes minutes to display a list of folders). However, when I use Finder's Go>Connect to Server, it allows me to enter and remember my userid and password, and the response time in accessing folders and files is extremely fast. How can I get the auto detection to allow me to login with my userid and password in the same manner that I login using Go>Connect to Server, so I get fast data access on the drive?

Hi, see if this helps...
Do the Connect to Server route, then...
If they in fact do show up on the Desktop, then create a new Folder maybe named Shares on/in the Desktop, drag all those Shares shown on the Desktop to that Folder, drag that Folder to the right side of the Dock between Applications & Trash, this should give you a popup menu to select from.:-)
Mount that Share once, then once the Globe Icon shows up on the Desktop, drag that Globe Icon to the right side of the Dock between Applications & Trash. You now have a Dynamic Mount, a quick click on the Icon in the Dock will connect you.
On the multiple Shortcuts...
Mount them all, when show up on the Desktop, then create a new Folder maybe named Shares on/in the Desktop, drag all those Shares shown on the Desktop to that Folder, (you can even rename them once there, if you wish), drag that Folder to the right side of the Dock between Applications & Trash, this should give you a popup menu to select from.:-)
To automount them, drag those Aliases to the Accounts Pref Pane's Login Items Window.

New WRT320N - slow internet access help!

Hi, we'e just installed a new WRT320N. We have broadband access via Virgin Broadband and have a fairly new modem. When we access the internet via the router it is really slow. This is the case whether the connection is wired (our PC doesn't have wireless, so the connection is wired - ie cable between router and modem and then cable between router and PC) or wireless (ie PC with wireless n card). If I unplug both and reboot, connection is initially fast and then slows down again.
If I connect the computer directly to the modem, the speed of internet access is fine. So there is nothing wrong with broadband generally, it is definitely something to do with the Linksys router and possibly the way it is communicating with the modem.
The one thing I've noticed is that when connected directly via modem without the router, speed is 100 mbps whereas when connected with Linksys router, speed is 1.0 Gbps.
Help! Thinking of giving up and returning the Linksys router and going with the one Virgin recommend (Netgear) but we'd rather not.
Virgin tech guys said we might need Linksys firmware update?
Anyone got any ideas? We're not v techie here and clueless .... Thanks v much!

100Mbps is the maximum supported on a Virgin modem, whereas your "gigabit" router is capable of outputting at 1Gbps or 1000Mbps. This is normal and has no bearing on your issue.
Go into the router config page at 192.168.1.1, change the MTU size to 1350, reboot both modem and router and see if that makes any difference.
Also check what version of firmware you have, it will tell you in the config (top right hand corner usually)
The latest available here is: Ver.1.0.03 build 10

Connecting Wireless N Router to Existing Fios Router for NAS Access

What I'm Trying To Do:
    I have a 1TB Western Digital MyBook Live as my new NAS for accessing music, photos, video. Accessing this data through the Actiontec MI424WR Wireless 802.11b/g is not the best performance. I want to add in a wireless-N router to the mix but know I have to keep my existing Fios Router in the mix.
    Understanding that the Gigabit part of a wireless-N Gigabit router is for the wired speed increase, do I need to get a gigabit router for when I plug in my NAS, or does that not make a difference.
     Basically, I know that the wireless-N will get me better access wirelessly, but will connecting the NAS via Gigabit give me an extra boost as well?
According to most posts, getting a wireless-N router directly from Fios is near impossible, so bridging a new router to the existing one seems like the best bet.
Thanks for any help anyone has.

I bridged an N router to my MI424WR,which is also an N router and really did not notice a big performance jump,i am satisfied with the MI424WR.even though my linskys N router is more expensive.

Time machine running slow and slowing network access

I have had and continue to have issues with wifi on my MBP. Those are pretty well summarized in https://discussions.apple.com/thread/5535320?start=30&tstart=0. I've been able to make mt system usable with some of the less dodgy workarounds in that thread ( like keeping a ping on my router running )
That thread really doesn't mention the issues I've been having with time machine though, so I thought I'd bring this up here. Whenever time machine starts up, Safari and mail become unresponsive. It's worst when TM is "preparing" of "cleaningup", though barely usable during the actual backup. Mostly, I can work around that too, but occationally, TM will find GB of data to be backed up and lock up my mac for a day. Here's a recent example:

This is on an AC router. My peak throughput shows 19 Mb/s on menu meters, so, not great, but not this slow. Mostly, the network activity is nothing with short bursts of higher throughput.
I'm hoping this will be addressed in 10.9.2. In the mean time, are there any workarounds to get past this issue short of turning off TM?
Thanks,

These instructions were taken from Mac OS X Hints at:
http://hints.macworld.com/article.php?story=20050302225659382
The Unix program dd is a disk copying util that you can use at the command line in order to make a disk image. It makes a bit-by-bit copy of the drive it's copying, caring nothing about filesystem type, files, or anything else. It's a great way to workaround the need for Norton Ghost.
Normally, in order to make a disk image, the disk you're copying from has to be able to spin up and talk -- in other words, it's OK to make a copy if the disk is healthy. But what happens when your disk is becoming a doorstop? As long as it continues to spin, even with physical damage on the drive, dd and Mac OS X will get you out of the fire.
We had a situation recently where a friend sent a disk to us that had hard physical errors on it. It would boot in Windows, but then it would hit one of these scratch marks and just die. We fired up dd, and it started OK, but stopped at the same physical error location -- complaining about a Hard Error.
So the workaround was to designate the dd mode as noerror -- which just slides over the hard stops, and to add the mode sync, which fills the image with nulls at that point. We did it on BSD Unix, but as long as you can get the hard drive attached to your Mac, the command is the same:
dd bs=512 if=/dev/rXX# of=/some_dir/foo.dmg conv=noerror,sync
The bs=512 designates block size, and the if=/dev/rXX# is the UNIX path to the actual disk device. Make sure that the chosen directory (some_dir) has enough room to take the entire disk image -- which will be equal to the size of the drive. Since dd doesn't care about the contents of the drive, it copies every bit on the thing, so you get an image equal to the disk's capacity. A really big file. One workaround is to put it on a RAID array.
Once you've established the disk image (in this example, foo.dmg), you're almost home. Here's where your Mac OS X box is far and away the best thing to have. In this example, the dd output file is foo.dmg. You have to realize that this is an exact copy of a busted drive, but the "holes" are filled with nulls. As long as the damage isn't to the boot sector, though, when you double-click on it, Mac OS X mounts it without breathing hard ... who cares if it's FAT32, NTFS, whatever.
Due to the size of the image that we were copying, we put it on a RAID array, and had to access the image over the network -- it still mounted fine. In straight UNIX, if you try to mount a disk image, it complains that there is "no block device" and fails. Once your image is mounted, it appears in your Finder, and then it's easy work to retrieve the critical files from the image -- usually things like .doc files and .xls files and the lot.
Finally, since your disk is actually dying, once you have your image, you can drop it to tape or something and you've not only recovered your files, you've made a viable backup as well. Once again, that which destroys a Windows box becomes a play thing to a Mac OS X box.

Macbook pro mid-2012 13" has very slow disk access

Until 3 days ago my macbook pro mid-2012 13" running OX 10.8.3 was running fine. Then, it showed very slow response anytime it had to access the hard disk. After doing the usual checks and disk first aid repairs to no avail, I booted from my external disk with an older copy of my hard disk and everything then worked as normal, except when I accessed the internal hard disk, then it crawled once again (spinning beach ball, took many seconds just to open a finder window and then several minutes to display the contents). I ran the Apple Hardware Tests and it said everything was fine, even though it tooks several minutes before the test would actually start. I also ran the program BlackMagic Speed Disk to find out if the disk was having transfer speed problems and it showed a respectible transfer rate (60MB/s), not great but not like the 0.3MB/s I was getting when I tried to back up the internal disk. I was using Carbon Copy Cloner to try to back up the internal disk but had to give up since at 0.3MB/s, it would take days to back up the 250GB on the disk. I found on the web that using "restore" in Disk Utility, I could do a disk copy without the file by file copy which allowed me to back up my disk in "only" 6 hours. Booting from my newly made copy on an external disk worked fine and ran at nearly normal speed (slightly slower since it was an external disk running through USB2). As a final attempt to prove this was a disk problem, I erased the internal disk and reinstalled OSX 10.8. I am still waiting for this install to finish, it has been 5 hours although the progress bar said it should be done in 20 minutes. This was fairly convincing evidence that it is not a software or settings problem. However, all my web searches could find no other case of a problem like mine. I presume I have a failed hard disk but as all the diagnostic programs say it is working fine, I was hesitating to bring it in without hard diagnostic evidence. If anyone knows what might be the problem, it would be much appreciated to hear from you.

It should not take 5 hours to install Mac OS X. There is something wrong with the disk. Try reformatting where you do a wipe of the drive (an select the option to write zeros which will remap bad sectors). Then try to install MAc OS X.
I got this information from here:

Back up your data.
Use Time Machine or a system cloning utility to create a full and restorable backup of your data. If you suspect bad blocks, then when cloning you might consider not using a "block-level" copy process, since this will likely run into problems.
Boot to the utilities DVD.
If you have a boot DVD for a tool like Drive Genius or another drive utility, then boot to that; if not, use your OS X installation DVD (once you select your language, open Disk Utility from the Utilities menu).
Format the drive.
Using your selected utility, format the drive and check for bad blocks. If you are using Disk Utility, click the Erase tab, click the Options button, and then select the option to write zeros to the disk (you do not need to do multipass erase options, as this will provide no additional benefit for managing bad blocks). Writing to zeros may take a couple of hours depending on the size of the drive, but when done the drive will have remapped any blocks that were not reliably read.
Restore the OS installation.
If you have used Time Machine to create your backup, boot to your OS X installation DVD (if you are not using Disk Utility) and use the option in the Utilities menu to restore from backup. Attach your Time Machine drive and then proceed with the restoration, selecting the newest backup as the one to restore to your system. If you have used a system cloning tool, then attach the cloned drive and boot off of it (hold the Option key at start-up to select it from the boot menu). When you are booted to the cloned drive, run your cloning utility to copy the installation back to the computer's main boot drive.An optional approach here is to perform a full reinstallation of the OS from your installation DVD, and then migrate your data, applications, and settings from either the clone or the Time Machine backups using Apple's Migration Assistant.

Mac Mini slow when accessing hd - NVidia MCP79 SATA Driver Problem?

I bought a Mac Mini (Early 2009) a while ago. Unfortunately i have a problem concerning speed and responseability which i couldnt solve even with a lot of googleing.
I noticed that problem first time when i tried to play a video file from hd. The video does not play as smooth as it should. It stutters from time to time. It is like a short interruption. The picture freezes for half a second and replays the lost frames very fast after that. These freezes do not occure periodically. It seems to appear randomly. The wierd thing is that the cpu usage is very low and there is enough free ram and disk space.
So i think its not a ressource problem. I noticed that these freezes do not only affect video playback. The whole system is kind of unresponsive. And thats the the case if there is some sort of hd or dvd access. When i try to copy a huge file these freezes are increasing rapidly. The more hd access the more the system is unresponsive and cannot be used anymore.
All these effects reminded me of a faulty dma/udma setting on windows machines. So i tried to check the transfer mode for my macs hd controler. But i didnt find any place where to check that. And i dont really think it is running in pio mode because that would result in a high cpu usage.
I played around a little bit to understand whats going on. So this is what i found out:
When i play a video from the hd its stuttering. It increases if i copy a file from or to the hd. Copying a file from the dvd-rom increases the effect as well. It is not influenced by a copy from AND to an external usb hd. And the whole effects do not appear under Windows Vista no matter how much i acces the hd.
So i come to the conclusion that there must be something wrong with the SATA controler driver which is a NVidia MCP79. Unfortunately i have no idea what i can do to solve this problem. And i didnt find any advice or something in the internet.
So i would appreciate any suggestions.

Ok, I think I was jumping to conclusion. Disabling journaling didnt remove the problem. It just seemed so because my problem is much less distinct with Leopard. Bad luck I guess.
kmac1036, to answer your questions. For sure I dont have warranty anymore. Maybee I should have posted that I upgraded my Mac to 3 GB RAM. Furthermore I replaced the original Hitachi HD with a Western Digital 500 GB model.
Somehow that may be connected to my problem. I've read that many people have problems with the WD HD and those beachballing issues with SN. (I do so too)
But my performance problem when accessing the HD did also exist with the Hitachi. In fact the Mini was extremly slow with the original 1 GB RAM. I think putting some additional memory into the machine helped because it reduced hd accesses.
Ok, I am not an expert. But if I had to guess I would say the following seems to happen. There may be an operation in the hd driver that takes longer than it should. Because of that it maintains cpu cycles and prevents the kernel to continue scheduling. That would explain why the freezes are not connected to a high cpu usage and why the systems seems to catch up things after the freeze very fast.
