Disk access extremely slow after 10.5.2 Update

I did the update to 10.5.2 today.
1. I tried to update via Software Update. The update started but then stopped with an Error message (Contact Support) and the system freezed. There was just the spinning wheel on blue background for more than one hour. No more harddisk activity. I finally rebooted (hard way). After a reboot I had a somehow upgraded system. But many things did not work anymore (most applications crashed, mail could not access keychain items anymore, etcpp)
2. Then I downloaded the complete Update package to do a manual update (happily firefox still worked). After a manual install it worked. It installed fine and rebooted. Now everything works as it should with the only problem that everything is extremly slow. Starting an application lasts about double the time as normal, loading files takes 3 to 4 times more time than with 10.5.1
To fix these issues I tried several things:
- Fixed permissions
- Cleared all cache files and forced system to rebuild them
- Severall reboots
- Waited until backup completed and Spotlight index was rebuilt
Bootup time is now fine (more or less). Just a little slower than 10.5.1. Application start is still slow but better. But the file access is still extremly slow. This can be observed very well in Parallels which still works fine, but needs 3 to 4 times longer to start (so do all applications within parallels). I checked CPU (Activity Monitor) but could not see anything special.
Any ideas what could be the reason for this behaviour and (more important) how to possibly fix this? I'm thinking about going back to 10.5.1 with time-machine and then try it again with the package install.
Any help/ideas would be appreciated.

Is it slow wireless LAN behavior affecting Time Machine? Check out the third page of this thread, specificallly the post by John Albergo about "delay_ack."

My mbp (mid 2010) is running extremely slow after installing some mavericks updates on May 22nd.

My mbp (mid 2010) is running extremely slow after installing some mavericks updates on May 22nd. Earlier I thought this behavior is due to spotlight indexing but it finished after 3 days. I deleted all caches from library. But no luck, still running extremely slow. I checked activity monitor for cpu usage, it shows above 90% is idle. The memory usage always shows PM - 4 GB, Memory Used 3.96 GB, VM - 4 GB, Swaped used 0 bytes, App Memory 1.82 GB, File Cache 1.44 GB, Wired Memory 480 MB.
Thanks in adavnce for help.

Was it the combo updater that was installed or the OS X 10.9.3 update. There is a difference.
MORE INFO ON WHY RUNNING COMBO FIXES ISSUES
Apple updates available from the Software Update application are incremental updates. Delta updates are also incremental updates and are available from Apple Downloads (software updates are generally smaller than delta updates). The Combo updates contain all incremental updates and will update files that could have become corrupted.
Combo updaters will install on the same version as they're applying--no need to roll back or do a clean install. So if you think you've got a borked 10.8.4 install from a regular update, just run the 10.8.4 Combo Updater on that system.
"Delta" updaters can only take you from one version to the next. For example: 10.9.1 to 10.9.2. If somehow the 10.9.2 is missing something it should have, and that something isn't changed between 10.9.1 and 10.9.2 it will still be stale after the delta update.

Finder/Disk Access Extremely Slow

I have a G4 867 (MDD) running OS 10.4.6. After putting my computer to sleep last night, I woke up this morning to find hanging at the login-from-sleep screen. I force-restarted, and since that point the computer, and especially some components of the Finder, has been running EXTREMELY slow.
Symptoms:
-Hard drives are slow to appear (I have two on the primary channel and two on the secondary). They will eventually show up, but it can take over a minute for drives other than the startup drive. When I scan them with Disk Utility, they appear fine.
-Using menus and accessing files in the Finder can take upwards of a minute or so. Likewise, switching between programs can induce waits of about 30 seconds.
-Curiously, once inside a program (say, Safari or iTunes), no problems exist local to the program, and it can run nearly unaffected... but if I need to change applications or access a file outside the program, the problems surface.
Things I've tried:
-Restarting.
-Trashing my Finder prefs.
-Zapping the PRAM.
-Resetting the PMU.
-Running Disk Utility.
-Running Yasu.
-Reinstalling the 10.4.6 Update.
-Trying to reinstall Tiger (which failed; initially, the DVD couldn't see the drives- then, after I checked them with Disk Utility, it could see them but failed to install after checking the DVD and asked me to restart)
Can anyone help?
G4 Dual 867 (Mirrored Drive Doors) Mac OS X (10.4.6) 2 GB RAM, ATI Radeon 9800 Pro AGP

I got my AE and Seagate FreeAgent Pro hard drive
yesturday and I have the exact same problem.
If I hook up the drive to the computer directly it is
very very fast.
If I hook it up to the AE it takes about 2 hours to
move a couple fils totaling 2 gigs over ETHERNET!
If I transfer the same files over the same network
between 2 computers the speed is much much faster.
Is this normal or some nasty firmware bug. It almost
feels like the AE is using USB 1.0 for some reason.
You guys are funny. How about checking out the specs of USB 2.0 and 802.11g/n?
Go here:
http://en.wikipedia.org/wiki/802.11g#802.11g
and here:
http://en.wikipedia.org/wiki/USB_2.0
Firewire vs. USB tests are here:
http://www.g4tv.com/techtvvault/features/39129/USB20_Versus_FireWirepg3.html
802.11g:
Release Date Op. Frequency Data Rate (Typ) Data Rate (Max) Range (Indoor)
June 2003 2.4 GHz 19 Mbit/s 54 Mbit/s ~35 meters
802.11n:
Release Date Op. Frequency Data Rate (Typ) Data Rate (Max) Range (Indoor)
Mid 2008 5 GHz and/or 2.4 GHz 74 Mbit/s 248 Mbit/s (2 stream) ~70 meters
Bottom line: 802.11n typical is 74Mbps, 802.11g typical is 19Mbps. USB 2.0 typical is 50Mbps.
On the average, you should expect your speed to drop by over 50% when connecting the USB drive to AESB using an 802.11g device. If your device is 802.11n, then you should have pretty much similar performance.
Now, if you increase the distance from your base station, or you put walls in between, the performance of 802.11g will go down "dramatically", all the way to 2-3Mbps, easy. Not so for 802.11n, which behaves much better at longer distances.

USB Disk access "Extremely" Slow

I am unable to use my network disk essentially because the disk access write/read times are SO SLOW...I am better off running backups by connecting my disk directly to the compter. Does anyone else have this problem?
It took 5 Minutes to read my Music directory; connected directly via the same cable it takes seconds.
What gives?
Any help would be appreciated.

Outlook 2010/13 Laptop Calendar access extremely slow after opening shared calendar

I have a problem with several laptops running Win 7 Ultimate on a network running SBS 2008 (Exch 2007) when they are on the internal network. Outlook response is fine until they tick any shared calendar (either shared by the user or with full access
to the mailbox granted at the server level)- the response of the calendar screen for the
local users calendar or the shared calendar
when using the advance or retreat arrows on the weeks drops down to roughly 20 seconds to advance to the next week, if the shared calendar is then unticked the speed stays slow for accessing the local calendar. if the user exits outlook and restarts
it the speed for accessing their own calendar returns to normal until they open another shared calendar.
this is a problem that has started within the last couple of months. SP are up to date on the windows and office.
I have tried ticking the download shared folders on and off, and also switching to using HTTP instead of TCPIP through the outlook anywhere. they run in cached mode as they are laptops- uncached is not an option
network access is fine
The problem affects some users on the network but not others. the problem shows on office 2010 and 2013. they don't appear to have the problem when they are out of the office.
Any thoughts anyone?

If you run your profile in Exchange cache mode and enable "Download share folders", please try to run SCANPST file to fix the OST/PST file and check the result.

By the way, does it for all shared calendr when you go to access them?

Time Machine to AFP volume is extremely slow after 10.5.2 update

I remember the time, after I have just installed the very first version of Leopard, when Time Machine was working with close to physical speed of my wireless network. Incremental backups would take less than a minute.
Comes 10.5.1. Time Machine became slower, but still tolerable: it might take up to 10 minutes to do an hourly backup.
Comes 10.5.2. Now Time Machine might take a couple of hours to do its "hourly" backup! 99% of the time it spends backing stuff up - when it shows the progress of the backup. So right now it says it's backing up 34.1 megabytes, and then it stopped at 1.4 megabytes, spent there about 15 minutes. Then it continued to about 9.5 megabytes, spend another 20 minutes there, without any progress, no CPU usage, very little network usage. Then it progressed to about 10.5 megabytes, and stuck again. Now it's at 15.2 megabytes, and been there for about 10 minutes already.
I use Airport Extreme base station with 802.11n at 5GHz, and the backup volume is on my Mac Mini, connected to AEBS via an ethernet cable, and during the phases when Time Machine gets stuck, I tested how the network works from my MacBook Pro, which I'm trying to backup to Mac Mini - constantly getting about 8-9 megabytes per second transfer rate, so clearly it's not that my wireless network is experiencing issues. Besides, the same problem persists even if I plug Ethernet cable directly into my MacBook Pro.
I've cleaned all caches, repaired permissions, repaired all volumes, rebuilt Spotlight indices on both my MacBook Pro and in the backup sparse bundle. The only thing it solved is insanely long "Preparing for backup" issue, but it DIDN'T solve the slow backup I have just described.
For comparison: rsync takes about a minute to do a full sync of my entire hard drive to the same AFP volume. Apple Backup 3.1.2 takes about as much. Time Machine - hours. I fail to even begin to imagine what in a world might they be doing there, spending this much time copying 34.1 megabytes of data over the network.
P.S. As I finish writing this, the backup progress is still at 15.2 magebytes. About 15 minutes now. A little over an hour now and not even half of the 34 megabytes is completed.

Running extremely slow after most recent software update. Would love some help troubleshooting and fixing, thank you!

Hi folks. Since my last software update, my computer has slowed to a near halt. Help!
I have a late 2009 MacBook Pro, running OS X 10.8.2. 2.26 Ghz / 8 gb memory.
I went into the Disk Utility and ran "verify disk," and got an "ok." Verified and repaired disk permissions. No idea if they're relevant.
At this moment the activity monitor is showing 3.79 gb of free memory -- 10 minutes ago, when I was doing nothing particularly differently, it showed all 7.99 gb in use (active and inactive -- I have. No idea what this means.)
It's all beach balls around here, all the time. Any ideas?

Your problem is excessive swapping of data between physical memory and virtual memory.
That can happen for two reasons:
You have a long-running process with a memory leak (i.e., a bug), or
You don't have enough memory installed for your usage pattern.
Tracking down a memory leak can be difficult, and it may come down to a process of elimination. In Activity Monitor, select All Processes from the menu in the toolbar, if not already selected. Click the heading of the Real Mem column in the process table twice to sort the table with the highest value at the top. If you don't see that column, select
View ▹ Columns ▹ Real Memory
from the menu bar.
If one process (excluding "kernel_task") is using much more memory than all the others, that could be an indication of a leak. A better indication would be a process that continually grabs more and more memory over time without ever releasing it.
If you don't have an obvious memory leak, your options are to install more memory (if possible) or to run fewer programs simultaneously.
The next suggestion is only for users familiar with the shell. For a more precise, but potentially misleading, test, run the following command:
sudo leaks -nocontext -nostacks process | grep total
where process is the name of a process you suspect of leaking memory. Almost every process will leak some memory; the question is how much, and especially how much the leak increases with time. I can’t be more specific. See the leaks(1) man page and the Apple developer documentation for details:
Memory Usage Performance Guidelines: About the Virtual Memory System

Iphone 4s is extremely slow after 5.1.1 update

Since updating to the latest (5.1.1) my phone is barely usable for anything mroe than 'just' a phone and basic texting.
Web browsing is terribly slow - regardless of if using data network or wireless connection at home. Apps are slow to respond and often the touch screen doesn't even register being touched or registers the touch incorrectly (wrong position for ex.)

I am aware what reverting to default means - unless you're a developer yourself, probably more aware than you are.
The problem is the update, not apps installed (and fyi yes I have reverted to default - as have many others that I've seen posting even here, and having issues still) but rather the update. This isn't a request for assistance. This is a report of an issue - and of a disgruntled user
back-to back-to back updates released and causing people issues and then innane attempts at 'fixing' the issue by telling people to jump through hoops until they get sick of trying and then just deal with the issues in hopes of an update that actually works (ie: resolves issues without causing more and worse issues) leads to customers taking business elsewhere.
which is what I'll be doing. My wife will be getting a new phone in july and as of right now it certainly wont be an apple product.

I have a 13 inch mac book pro 10.6.8 8gb 2.3 gfz intel core i5

What did Apple tell you about what they did (or did not) find here?
See if working on the main disk is any faster.
USB2 is glacial, as I/O interconnects go. And USB2 disks have been known to fail, or sometimes to drop back to USB1 speeds, too. FireWire 800 is substantially faster than USB2, but still not as fast as the internal drive connections can provide.
Put another way, start varying your configuration, and see which configuration changes (still) have the problem, and which don't.

IPhoto is extremely slow after upgrading to OSX Maveric

Has anyone noticed that iPhoto is extremely slow after upgrading to OSX Maverick

I've noticed that it isn't.
There are 9 different versions of iPhoto and they run on 8 different versions of the Operating System. The tricks and tips for dealing with issues vary depending on the version of iPhoto and the version of the OS. So to get help you need to give as much information as you can. Include things like:
- What version of iPhoto.
- What version of the Operating System.
- Details. As full a description of the problem as you can. For example, if you have a problem with exporting, then explain by describing how you are trying to export, and so on.
- History: Is this going on long? Has anything been installed or deleted? - Are there error messages?
- What steps have you tried already to solve the issue.
- Anything unusual about your set up? Or how you use iPhoto?
Anything else you can think of that might help someone understand the problem you have.

IPhone 3G is extremely slow after 4.0 update.

Both my sister and I have experienced our phones to be extremely slow after updating them. The messages take a few seconds to open, same with the apps. Also while typing, nothing will show up then all of a sudden everything you had typed will show up. It just seems like everything on the phone is slow. I've done some research on it, and everyone said to restore it. The people at Apple said not to do that unless it's the last resort. Is anyone else experiencing this?

Why post the same question twice ?

Blackberry Z10 became extremely slow after OS update to version 10.3.1.2243

Hi,
My Blackberry Z10 became extremely slow after OS update to version 10.3.1.2243. For example it sends text message 10-15 seconds after send button has been hit.
Can not answer the phone when a caller is calling (answer slide interface is unrespnsovie), if I want to launch any application screen turns black and nothing happens, etc.
Does anyone experience similar issues?
Thank you.
Michal.

Hi and Welcome to the Community!
A quick read of this site will answer your final question quite clearly. The "fix" depends on several factors, but given what you describe I recommend you immediately update, via AutoLoader, to the most recent version (.2582)...some of the prior versions contain some particularly challenging issues, which are reported to be fixed in this version.
Good luck and let us know!
Occam's Razor nearly always applies when troubleshooting technology issues!
