IMac link to 2Wire gateway gets slower over time

Hi All,
For the last couple of months I've had a situation where the airport signal drops off (and my download speed drops accordingly). When I start up I get "5 bars" from the wireless router. Then speed will drop, or pages fail to load, and I notice that Im getting just 1 or 2 bars. If I turn Airport off, then back on, it comes back at full strength and works for a while. The DSL router is a 2wire (ATT) that otherwise seems to work fine. I don't see much that I can adjust or configure with Airport or the IMac. The router is not too far away as the crow flies, but its a floor below. My mac mini and the wifes laptop seem pretty good. What can interfere with the signal. Also is the 801.1x security only, or something that yields stronger connections? THe online help for setting up the 801 in Airport was clear as mud. Suggestions? Thanks!

This is what I believe is happening. I don't see what I might not be freeing. I remove all event listeners and remove the TextFields from the display list. Is there anything else I need to do?
Currently I am displaying the frame rate. I see a frame rate starting at 30 and going down to 8 after several hours.
I also just started to display the memory:
tf.text = Number( System.totalMemory / 1024 / 1024 ).toFixed( 2 ) +' Mb';
I am interested to see if when the FPS goes down to < 10, if the memory is much larger.
Are there any tools that might help debug what might be happening?

Index Organized Table getting slow over time

Hello,
I recently discovered a problem in our our production environment:
We use an IOT to store search results in the form of primary keys (and additional data). This results in an excessive amount of INSERTs and DELETEs (the application is mainly a research tool). After some time, some statements on the IOT like SELECT COUNT(*) (optimizer using INDEX FAST FULL SCAN) take longer and longer, however the IOT index is used correctly by the optimizer and SELECTs which specify WHERE primk... (optimizer using INDEX RANGE SCAN) are executed with best performance.
It seems that the IOT somehow gets fragmented or unbalanced. Now my question ist, what's would be the best approach against that problem.
Would a daily ALTER TABLE ... MOVE ONLINE; be a good solution for example? Is this common practice with high volatile IOTs in 24x7 production environments?
Are there any better solutions for storing temporary search results?
Looking forward for your comments.
-sd

In addition to above mentioning...
Have you verified the distribution of IOT?
Like "ANALYZE INDEX .... VALIDATE STRUCTURE"? or "DBMS_STATS.GATHER_TABLE_STATS"?
It's natural that your full table scan(index fast full scan) gets slower in case that your IOT is getting bigger.
If you have lots of free leaf nodes, moving index will be beneficial although moving itself should be abvoided on busy time.
You also need to do sql trace and tkprof to measure how much workload your IOT is making.

WLAN getting slower over time.

If I download arch iso from my local server via scp, the connection begins with a speed of 2-3 MB/s, and slows permanently down until it reached 80Kb/s. If I do the same over Fast Ethernet, I get constant 11.3 MB/s. I have this problem on my router (701V) as well as on my accesspoint (WL0110), with wicd as well as with networkmanager. Hence I guess it is a driver problem.
I dont have any clue on how to solve this problem. Here some Info. Please ask if you need more.

There have been a few reports on here where Corsair RAM seems to have caused users a lot of grief with crashes.
The recommendation on here, mostly, is to only buy RAM from macsales.com or crucial.com as they guarantee their modules will work and offer a no quibble lifetime guarantee.
I'd put the original RAM back in, return the Corsair chips for a refund and re-order from one of those two companies.

Is ther a way to speed up a Mac? Mine has gotten slower and slower over time. When memory comes close to full would that have an effect on performance? Is there a way to determine unused programs/software to remove and free space?

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.

Data rate slows over time: Using Time Capsule (4th) and AirPort Express (1st)

Time Capsule using Airport Express to extend network.
Over 3-4 days my data rate gradually gets slower and slower until I have to reboot both TC and AE.
Fresh reboot gets me 10Mbs or better for a while and then slows over time to 2Mbs or less.
I can cable directly to the ISP modem, taking TC and AE out of the equation, and its smokin fast
No hair left to pull out, so any help or suggestions would be appreciated.

You have your wireless channels on auto.. it is usually better to control it.
You will notice I have different names for 2.4ghz and 5ghz.. then I can force the link to either band.
After you set Radio Channel selection to Manual,, click edit. You can then set the channels.
Lock the channels.. ie you take control and you set what the wireless channels will be.. when you extend wireless this works far better. The auto channel system has to run on the Extender.. but since the main base is fixed on the 2.4ghz so it will be also.. the only channel that can flap around is 5ghz (extender) since that is not under my control. Of course it is up to you to determine which channel works best.. I strongly recommend the upper channels for 2.4ghz and the lower channels for 5ghz.
So.. I have set 5ghz to 48 on the main base.. and the auto channel sets it to 149 in the extender.
One strange thing results from my setup .. (amongst many!!)
You cannot name the wireless for 5ghz in the extender.. so in my case the upstairs wireless extender has both 2.4ghz and 5ghz named TC24ghz.. nought that I can do about it. But it is not a big deal.
You can see the result in the wireless diagnostics. The last wireless I have put in the box.. it is named TC24ghz but is in fact running on 5ghz. That is just how the over automated system of the apple routers work.. If I could I would fix it.. and maybe shall via serial console at a later date.

Uupgrading the ram will help, 2gb simply isn't enough with Mavericks. Your iMac will use up to 6gb of ram,
Min. RAM Speed:
800 MHz
Details:
Supports 800 MHz PC2-6400 DDR2 SDRAM (200-pin SO-DIMM). Also see: How do you upgrade the RAM in this Aluminum iMac model? How much RAM does it actually support?
Standard RAM:
1 GB
Maximum RAM:
6 GB*
Details:
By default, 1 GB of RAM was installed as a single SO-DIMM module. One slot free. *Apple officially supports 4 GB of RAM, but third-parties have been able to upgrade the system to 6 GB of RAM using one 2 GB and one 4 GB SO-DIMM module. In the US (and many other countries), site sponsor Other World Computing sells memory -- as well as other upgrades -- for this iMac. In Australia, site sponsor RamCity sells memory and other upgrades for this iMac.
Get ram form either OWC http://eshop.macsales.com or Crucial http://www.crucial.com to avoid problems with incompatible ram.

Firefox gets slower and slower over time.

I have been using firefox for some time, Like it better than Safari generally, but I've noticed (and it has gotten worse with 3.6.x) that if you leave FF running for extended periods of time it gets slower and slower, does not seem to matter if add-ons are installed or not, and it gets REALLY bad after going in and out of flash based apps/games a couple times. It is not just a mac problem as this behaviour also happens on windows xp or newer, but windows OS needs to be rebooted daily anyways so most people won't notice.

Proceed with [[Basic Troubleshooting]] first of all.
You could also try running Firefox in [[Safe Mode]]. If it functions properly in that configuration, then one of your add-ons is the culprit.

AxGPIB runs slower over time

Using Measurement Studio 6.0 for VB but from within a Visual Studio 2005 CSharp app, the components used are the AxCWGPIB ? that interface to the GPIB bus
everything works except over time, like 1 hour, it becomes noticeably slower, after 10 hours the cpu useage is peaked around 100%, each transfer takes a few seconds. Am searching for any issues with this activeX, any leads appreciated.
rebooting the system makes it run faster, problem seems linked to the GPIB interface/driver which is the National Instruments/Measurement studio component that appears as AxCWGPIB
thanks for any assistance

yes thanks, I disabled the data logging and ran the tests that only did the gpib I/O. doing this, it would increase in cpu useage much faster than if everything gets run. Ive scoured the code for possible memory leaks
Is there supposed to be some special way to call and manage the Interop.CWInstrumentControlLibrary.dll or ?? from the C# form world?
the documentation is extremely limited, but I put the control into the form1, then make calls from the code. nothing to indicate that more is necessary, so what else is supposed to be done?
is there a difference between the cwgpib control in the dotnet version of Measurement Studio? or is it the same exact v1.4 for version 6.0?

Does the iPad get slower with time?

i have an iPad 4 for over a year. Does the iPad get slower with the passage of time or because of small amount of available?

As with any piece of electronics, the more stuff you get on there, the more clutter and the more 'junk' (not meaning offensively, just junk as extra files, fragmented files, etc) that it has to run through.
If you think it's getting too slow, you can fully back it up, then reset your iPad back to factory settings (erase all content and settings) and then restore from that backup.
It's not impossible, just something to do carefully because if you haven't backed everything up correctly, you will lose it. (content and apps from iTunes can always be redownloaded but content made on your iPad can be deleted if not backed up)
I've had my iPad 2 for almost three years now and really haven't noticed a major decline in function. So unless you see something drastic, I really wouldn't worry about it.

Faint ring around the edge of my display - getting worst over time

I have been noticing over time a faint ring around the edges of my display - mostly prevalent when screen is blank (I.e. rebooting) but is present at all times. It's color is faint gray and seems to be getting more noticeable over time. It's not a big issue - just wondering what it could be. It's possible that this imac is simply aging - it's on its 5th year. And, running strong!

Interesting. Can you post pics of the "ring"? Does the ring occur around areas of greatest use or or wear?

My Network gets slower with time capsule... why?

I Buy a Time Capsule for only for use it as backup HDD in my work but after i install it and configure it the network gets slower but onli with the machines that have the gateway configured, because the machines that dont have internet connection (no gateway and no DHCP only static ip), they are fast as allways
we use Windows Server enterprise 2008 r2 with ADSL connection and terminal server configured and a network domain on it.
and the machines have windows 7 and xp.
I hope someone know why this happened.
thanks.

And if you don't have luck on the SL forum then I'd recommend posting on the Airport forum. You can find that at:
