Memory sky rockets over time, poor performance.
I've noticed when I come home from work, my Fire Fox is performing incredibly bad. Tabs take awhile to open, mouse wheel scrolling has a delay, etc. You tube videos would pause and stutter on the video but audio is fine. I started to monitor it and its the fact my wife will open 10 windows, sometimes with tabs, but never fully close all of them. When I come home, its at 1.5-2.2gb of memory used in task manager. I tried about:memory and its littered with facebook mentions, even though no facebook tabs are open. She might have 1 or 2 tabs up for cooking recipes.
The only fix is to close FireFox all together and reopen it.
If I lose her opened tabs, she gets a little upset, so I have to kill the exe in task manager so when I reopen it it will offer to resume the previous session.
This is just a touch tedious after a few weeks.
Is there a different command or something I can do to leave current windows open and just flush out all that used memory?
This looks like it may have done it.
I only got to do it on Tuesday, but I cleared out a bunch of the unused extensions. So now just Adblock and an old Mouse Gestures Redox.
Came home last night and it was sitting at 300mb, instead of 1.7gb. Much nicer. Thanks.

2.5 GB memory, 2.8 GHz P4.
Using FF 3.6.16. Last 2 minor upgrades happened auto. , without my permission (another irritant).
I routinely clear the cache (all options checked off), and this has little to no effect on either #1 or #2. Whenever I restart FF, it takes less than 24 hours to get back to memory-hog state. Regardless of number of tabs - I've tested that too, even just a couple of tabs over time will see memory swallowed up.The battery alone is a $5 to $15 part. Hard drives vary in cost, and depending on the iMac, they may or may not be able to install a third party hard drive, or one resold through Apple. The resold through Apple drives tend to cost more. This article discusses the varying successes of third party drives on iMacs:

Firefox 4.0 RAM usage soars over time in Mac OSX 10.6.7 and is never freed
Firefox 4.0 RAM usage typically averages between 400-750MB for light usage (1-2 windows, 1-3 tabs each). Memory usage skyrockets over time, and/or if I open more tabs or windows where I've seen it consume well over 1 GB of RAM of my total 4 GB. Firefox 4.0 never seems to free much of this RAM relative to what it's consuming either.
The only plugins enabled are QuickTime, Flash and Java (and disabling any of these to use Firefox efficiently should not be required).
The worst I've ever seen was it using 1.27 GB of RAM when all I had open was Facebook (1 window, 0 tabs). Something is not right with this browser...Shouldn't it free what it isn't using?Same here. I upgraded to FF5 yesterday morning and by this morning FF was using 1.26GB RAM and over 1GB Virtual Memory (less than 24 hours). I've had this problem ever since I started using FF with version 3...
The only add-on I use is Firebug. -
Is there a way to speed up a Mac (similar to de-fragging on a PC)? Mine has gotten slower and slower over time.
When memory/disc comes close to full would that have an effect on performance? How should I determine what programs/software to remove and free space?Things You Can Do To Resolve Slow Downs
If your computer seems to be running slower here are some things you can do:
Start with visits to: OS X Maintenance - MacAttorney;
The X Lab: The X-FAQs;
The Safe Mac » Mac Performance Guide;
The Safe Mac » The myth of the dirty Mac;
Mac maintenance Quick Assist.
Boot into Safe Mode then repair your hard drive and permissions:
Repair the Hard Drive and Permissions Pre-Lion
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
Repair the Hard Drive - Lion/Mountain Lion/Mavericks
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the Utilites Menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD disk icon and click on the arrow button below.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported, then click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
Restart your computer normally and see if this has helped any. Next do some maintenance:
For situations Disk Utility cannot handle the best third-party utility is Disk Warrior; DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.x is now Intel Mac compatible.
Note: Alsoft ships DW on a bootable DVD that will startup Macs running Snow Leopard or earlier. It cannot start Macs that came with Lion or later pre-installed, however, DW will work on those models.
Suggestions for OS X Maintenance
OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep. Dependence upon third-party utilities to run the periodic maintenance scripts was significantly reduced since Tiger. These utilities have limited or no functionality with Snow Leopard or later and should not be installed.
OS X automatically defragments files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive.
Helpful Links Regarding Malware Protection
An excellent link to read is Tom Reed's Mac Malware Guide.
Also, visit The XLab FAQs and read Detecting and avoiding malware and spyware.
See these Apple articles:
Mac OS X Snow Leopard and malware detection
OS X Lion- Protect your Mac from malware
OS X Mountain Lion- Protect your Mac from malware
About file quarantine in OS X
If you require anti-virus protection I recommend using VirusBarrier Express 1.1.6 or Dr.Web Light both from the App Store. They're both free, and since they're from the App Store, they won't destabilize the system. (Thank you to Thomas Reed for these recommendations.)
Troubleshooting Applications
I recommend downloading a utility such as TinkerTool System, OnyX, Mavericks Cache Cleaner, or Cocktail that you can use for removing old log files and archives, clearing caches, etc. Corrupted cache, log, or temporary files can cause application or OS X crashes as well as kernel panics.
If you have Snow Leopard or Leopard, then for similar repairs install the freeware utility Applejack. If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the command line. Note that AppleJack 1.5 is required for Leopard. AppleJack 1.6 is compatible with Snow Leopard. Applejack does not work with Lion and later.
Basic Backup
For some people Time Machine will be more than adequate. Time Machine is part of OS X. There are two components:
1. A Time Machine preferences panel as part of System Preferences;
2. A Time Machine application located in the Applications folder. It is
used to manage backups and to restore backups. Time Machine
requires a backup drive that is at least twice the capacity of the
drive being backed up.
Alternatively, get an external drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
1. Carbon Copy Cloner
2. Get Backup
3. Deja Vu
4. SuperDuper!
5. Synk Pro
6. Tri-Backup
Visit The XLab FAQs and read the FAQ on backup and restore. Also read How to Back Up and Restore Your Files. For help with using Time Machine visit Pondini's Time Machine FAQ for help with all things Time Machine.
Referenced software can be found at MacUpdate.
Additional Hints
Be sure you have an adequate amount of RAM installed for the number of applications you run concurrently. Be sure you leave a minimum of 10% of the hard drive's capacity as free space.
Add more RAM. If your computer has less than 2 GBs of RAM and you are using OS X Leopard or later, then you can do with more RAM. Snow Leopard and Lion work much better with 4 GBs of RAM than their system minimums. The more concurrent applications you tend to use the more RAM you should have.
Always maintain at least 15 GBs or 10% of your hard drive's capacity as free space, whichever is greater. OS X is frequently accessing your hard drive, so providing adequate free space will keep things from slowing down.
Check for applications that may be hogging the CPU:
Pre-Mavericks
Open Activity Monitor in the Utilities folder. Select All Processes from the Processes dropdown menu. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time (>=70,) then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.
Mavericks and later
Open Activity Monitor in the Utilities folder. Select All Processes from the View menu. Click on the CPU tab in the toolbar. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time (>=70,) then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.
Often this problem occurs because of a corrupted cache or preferences file or an attempt to write to a corrupted log file. -
Shared nothing live migration over SMB. Poor performance
Hi,
I´m experiencing really poor performance when migrating VMs between newly installed server 2012 R2 Hyper-V hosts.
Hardware:
Dell M620 blades
256Gb RAM
2*8C Intel E5-2680 CPUs
Samsung 840 Pro 512Gb SSD running in Raid1
6* Intel X520 10G NICs connected to Force10 MXL enclosure switches
The NICs are using the latest drivers from Intel (18.7) and firmware version 14.5.9
The OS installation is pretty clean. Its Windows Server 2012 R2 + Dell OMSA + Dell HIT 4.6
I have removed the NIC teams and vmSwitch/vNICs to simplify the problem solving process. Now there is one nic configured with one IP. RSS is enabled, no VMQ.
The graphs are from 4 tests.
Test 1 and 2 are nttcp-tests to establish that the network is working as expected.
Test 3 is a shared nothing live migration of a live VM over SMB
Test 4 is a storage migration of the same VM when shut down. The VMs is transferred using BITS over http.
It´s obvious that the network and NICs can push a lot of data. Test 2 had a throughput of 1130MB/s (9Gb/s) using 4 threads. The disks can handle a lot more than 74MB/s, proven by test 4.
While the graph above doesn´t show the cpu load, I have verified that no cpu core was even close to running at 100% during test 3 and 4.
Any ideas?

Edited by: user5175632 on Oct 25, 2011 3:35 AMThis might be due to this bug raised for JDBC Client/Server connection
Bug 12969330 : MEMORY LEAK IN JDBC CS FOR CALLABLE/PREP STATEMENT W/ NUMPARM % 4 != 0
There is a leak in JDBC driver which seems to affect only C/S; it does not seem to affect direct or batch. ** This bug has been there since 11.2.1.6.0.
Here are few conditions which are needed for this bug to occur:
1. Application must be using a Client/server connection
2. Applications repeatedly does the following:
1. Create a PreparedStatement or CallableStatement
2. set or register IN, OUT or IN OUT parameters
3. Number of parameters is not an integral multiple of 4. It is the total number of parameters which matter; parameter type does not matter. JDBC driver leaks memory if the number of parameters in a PreparedStatement/CallableStatement are not an integral multiple of 4.
3. On a close 1-3 parameters can be leaked.
If your application deals with above scenario then there is a possible chance of the bug being hit. An example of a scenario :-
The below PreparedStatement has 1 parameter (so it's not an integral multiple of 4):
preparedStatement = connection.prepareStatement("SELECT col1 FROM Tab1 WHERE col2 = ? "); <===== Possible memory leak here
To workaround the bug, you can add 3 dummy parameters -- SELECT col1 FROM Tab1WHERE col2 = ? and 1=? and 1=? and 1=? and set parameters 2,3 and 4 to 1.
preparedStatement = connection.prepareStatement("SELECT col1 FROM Tab1WHERE col2 = ? and 1=? and 1=? and 1=? ");
I've seen this bug a couple of times now. I don't think there is a release yet which includes a fix. -
Audio performance deteriorating over time until Mavericks reinstall
I'm on the latest Mavericks, maxed-out 12-core Mac Pro. I use Steinberg Nuendo as my main audio DAW. It works like a dream... for a while... But after a few weeks it starts slowing down until Nuendo is almost unusable. Larger projects which normally run just fine become unworkable or very sluggish because they just overload the CPU, as if I was working with a 5 year old computer. This issue specifically targets audio performance, whether I use internal audio or my audio interface (UAD Apollo).
I've tried removing/uninstalling all non essential drivers, extensions etc, and reinstalled/updated everything I can't work without to the latest versions. I've tried unplugging everything except 1 monitor, keyboard, mouse and USB authorization sticks. Nothing makes a difference. It's like there's a virus that progressively slows down my system, but I have found no virus on my system, at least via MacKeeper.
Here is my temporary solution: Every few weeks I reinstall Mavericks (right now 10.9.3) via the Apple online recovery system (Command-R on startup). The problem goes away completely and my Mac Pro is blazing fast again... For a few weeks, until audio performance deteriorates and I have to reinstall Mavericks again. Apple tech support originally advised me to reinstall Mavericks on top of itself, and I was really happy the problem was fixed, but I didn't know it would keep sneaking in over and over again.
This is the third time I have to reinstall Mavericks via online Recovery, and I am still baffled as to what could possibly get worse over time in this manner, and also specifically target audio performance! It's like some sort of cache is getting filled-up somewhere and overloading some of the computer's functions over time. Whatever this is, it gets reset during a reinstall.
If anyone has any ideas or hunches, they would be really appreciated!
PS: I've posted the same issue in the "Mac Pro" section to make sure I get the most coverage. I don't expect too many answers since not too many people have the Mac Pro yet and this is a targeted inquiry.Make sure you got all the parts and pieces.

Memory pool Code Cache increasing over time
Hi,
We are using JConsole to monitor some of our servers which are running JCAPS. We have a couple of JCAPS applications deployed on these servers. We are using JConsole to monitor this server and we can see that the Memory pool Code Cache seems to be increasing over time. It is around 21M at the moment and has gone up from 18M 3 days back. Is this accepted behavior? Should it not be a varying graph, going down coming back up again?
Any help in this direction is much appreciated.

Slow Performance Over time, Drawing Access Forms
we've been using a small access database for almost a year now, written from scratch using only Access 2013
over time drawing of one of the forms slows right down, once the form is draw its fine, but if you switch to a different form at the top then switch back it draws slow, maybe 7-8 seconds compared to the usual 1 second, sometimes it can work all day no problem,
sometimes after an hour it starts drawing the form slow, the only way to cure it is to restart the machine.
Logging off and logging back on doesn't cure it, only restarting it, it does get restarted every night automatically as an attempt to help the problem
this happens on 2 machines, both have intel HD graphics, (previously one was using a NVidia GT 250 which had appalling performance in design mode (even with hardware acceleration disabled) so we switched to the on-board, although this issue happens
with both machines)
Back end gets compacted/and repaired every night on a schedule as I did notice a big slow down if you let that go a couple of weeks, I've decompiled/recompiled the front end, short of re-writing the form I'm not sure what to do, it does have a lot of controls,
around 30 textboxes 1 combo box + 20 or so labels and 4 buttons, one embedded report, it only happens on this one form, I have embedded reports in other forms which don't have the same issue and have the same number of controls.
I'm a bit of a loss, its not a huge issue, but just an annoyance, when I get time I'm tempted to try recreating the form from scratch, but there is a lot of VBA code behind it, before trying that just wondering if there are any suggestions to improve performance?
*edit* the form is loaded from a list of customers, so it gets opened closed a lot, I thought simply hiding the form instead of loading/unloading all the time would speed it up, it does slightly improve the speed after viewing the second lot of details,
however it suffers the safe fate of slowing down over time, it seems to be only drawing the form and not accessing the dbI think you would benefit from a code review by a strong Access developer. What you are describing is not normal and may be caused by systematic programming choices.
-Tom. Microsoft Access MVP
Just wondering, once this does happen going into design mode on any form is slow to draw, but only the one form at runtime once it starts happening.
the only visible difference apart from waiting is seeing the 'property sheet' on the right hand side gets visibly drawn left to right on any form once this happens, switch back to form view you see it get wiped out slowly, fade from left to right as it blanks
the form out
I had this 'slow' behaviour constantly with the NVidia card in one of our machines, even on new blank databases.
I'm not even sure if this is linked to the form I've made or not, its just the only reason I notice it is that it's frustrating to use.
Is this code review idea something that people volunteer to check or is it a paid service? -
Available memory decreases over time
Hello,
I noticed that under ICS, the available memory decreases over time. After about 10-15 days of use without reboot, the available memory goes from approx 150Mb to 70Mb. It is not my applications that are taking the RAM but it rather seems that it is the OS itself that is using it.
Under the Settings>apps>running> the first portion of the memory (OS I presume) keeps taking more space. Then after 10-15 days, the phone slows down and becomes jerky. After a reboot, everything goes back to normal.
I can't remember if it was the same under GB. Anyone experiencing this?Thanks for you replies guys. This isn't so great to have to reboot every so often. There must be a memory leak somewhere.
Invar, even if I close an app, there is still a bunch of memory that's taken by the OS that doesn't get released. It's ok that apps take RAM so that they load faster when I need them, but when the OS takes up all the RAM, then the apps have little RAM to play with and it becomes laggy.
I definitely won't be rebooting every day. I like my phone to just work and forget about it. In my case, I can probably wait about 10 days until it starts becoming laggy again.
Yea, I do miss phones of yesterday where they just worked (I'm thinking dumb phones, BB). Android is cool, we just need the bugs to be fixed. I hope 4.0.4 fixes that. -
Poor Time Capsule Performance in a Roaming Configuration
I have a bit of an odd problem. I recently added a Time Capsule (4th Gen) to my network alongside my existing Airport Extreme (4th Gen). Both devices are set in Bridge Mode and connected to a 1000Base-T backbone which accesses the Internet through my AT&T U-Verse gateway (WiFi off). My intention is to have the devices in a roaming network with the AE upstairs and the TC downstairs in my office.
Coverage-wise this has been excellent, but performance has not been up to par. Through a great deal of troubleshooting, hair-pulling, and even a replacement TC, I have determined that, for some reason, the TC has trouble forwarding my frames if it is on the same SSID as the AE. (Which is, of course, a required for a real roaming network.)
Both devices are running 7.6 firmware and I have manually set the radio channels at the far extremes from each other in both bands to rule out interference. My neighbors' APs are still visible, but aren't causing any intereference in those bands.
If I configure both devices with identical WiFi settings (SSID, WPA2-Personal, PSK, etc.) devices that are associated with the TC experience very poor performance. The radio part of the connection is great. (Strong signal, low noise, etc.) Data throughput is awful, though. Web pages won't load, and when I ping local devices on the wired side of the network I'm lucky to get 500ms round-trip. Most of the pings are in the >1000ms range with many timeouts.
Devices connected to the AE, however, average about 1ms round-trip to the same devies and see no issues getting to the Internet or transfering files locally. In fact, Time Machine backups work just fine to the TC.
That said, if I simply change the SSID for the TC radio, leaving *everything else* the same, it works like a dream. Unfortunately, that isn't exactly the roaming network I would like to have.
Has anybody else seen this behavior or have any ideas on how to fix it? I'm stumped. What really concerns me is that I've seen this with two different TCs.
For the record, I have already reflashed, defaulted, and configured both devices from scratch with no change in performance.Replying to my own post is probably bad juju, but I thought I'd provide an update for those who may have also seen this issue.
First, it turns out that having the separate SSIDs didn't actually matter. WIthin a day or two of my OP, the Time Capsule on the separate SSID began exhibiting the same problem as before. It seems that this is part of the problem. When it occurs it can take a few days to a week to turn up, but it can also happen right away.
Eventually, the Time Capsule began to exhibit other issues as well. For instance, in my testing, I would need to reboot it to apply new settings, but it would hang on a reboot for 20 minutes or more and I would have to pull the power cable. I finally called Apple and they replaced it again.
When the new Time Capsule arrived, everything seemed to work well, but before I was even able to get the backups moved from the old one to the new one, the problem showed up on the new one.
At this point, I found a few forum threads where other people were having similar problems and were able to get around them by downgrading form firmware 7.6 to 7.5.2. I was about to try that when Apple released 7.6.1.
On a whim, I decided to try the new release, even though Apple only referred to vague WiFi performance fixes. I have to say that I noticed immediate improvement across the board.
So far, so good. I am hopeful that the new 7.6.1 is the fix to the problem. -
Internet performance degrades over time with AirPort Extreme
Hello, we have an AirPort Extreme (802.11n) which is about two years old, and I've noticed lately that if I don't reset it for say, a month or so, internet speeds become extremely slow, and there is no way to regain normal speeds without resetting it... I was just wondering if this is normal for an AirPort Extreme, and also, could this be due to the age of the unit (i.e. do AirPort Extremes slowly lose performance over time, and is buying a new one the only answer)? Any help would be much appreciated. Thanks!
U have to find a good channel.
on 2.4ghz this is 6 unless other routers in the area are using it. if so use another channel.
Other things that can interfere: Microwave oven, frige - any thing that emits em fields
5ghz is better.
vicinity of your laptop makes a big difference - i get up to 57Mbps on speedtest net in vicinity of time capsule @ 5ghz.
Best performance is on ethernet cable.
Hope this helps -
Hi All,
I have users complaining of poor performance for TCP applications over a site to site VPN.
I would like to know if anyone knows what to look for when trying to see if we need to reduce the MTU on each side of the VPN.
I dont want to reconfigure MTU unless I have to because one of the two sites is the centre of the hub and I will most likely have to configure it for all of the other sites if I configure it for the one.
the VPNs run between 5510 devices running 7.08 and 8.21
thanks very much for any help

Any WebI reports / graphs for job chain performance over time?
I am trying to get reports over time that contain job and job chain information such as job chain, job description, elapsed time, job status, etc to allow for trend reporting against the job schedules. Thanks for any help. I would have thought that there was some basic reporting that could execute and be saved for reporting and reference.
Hi Robert,
For WebI/Graph report, you need to create the Dashboard but it will not give details which you required. It will be created on basis over day, time and dialer. You can find the option there for Graph/Techno etc.
If you want to create the report, please refer to below thread:

General poor performance of my Mac mini
I have been using my mac mini for over a year, it continues to frustrate me how slow and unresponsive it can be even though I do very little with it, i.e organise photos and browse the web - usually looking for solutions to the poor performance problem!
I came a cross this app that has given me lots of information, unfortunately with my limited IT know-how there is nothing here that gives me any clues, as to the cause of the problem. I guess the red font is not good?
I'm sorry i can't be more specific about the problem other than to say that iPhoto and Safari the two programmes i use way more often than any other, keep giving me the beach ball. My internet speed is ok 25 Mbps down - 4.5 Mbps
Is there anything here that stands out as being wrong? if so any suggestions/ instructions for what I should do?
p.s. i had to quit Safari while writing this and have a report for this if it helps?
Any help much appreciated.
Problem description:
My mac is just generally very slow. I only use it to look at the internet and manage photos.

Thank you for taking the time to respond.
I got this information from a time when I was opening up iPhoto, and then going to the iCloud folder. To be honest it wasn't the most disastrous of events, I did get a few beachballs and when I opened up a shared folder the photos weren't loaded as normal. As I get more lengthy delays in carrying out any activities I will post back the console results.
Just as a bit more info, I don't consider my problem an update to Yosemite problem, if anything since updating performance has been improved from Mavericks.
Do you have any comments about upgrading RAM from the 4GB I have?
Should I act on any of the messages in red from the EtreCheck report?
Many Thanks
Duncan
