Performance problems with a Mac can seem to be mysterious at times. The system that was running at high speed suddenly comes to a crawl for no apparent reason. Web pages that loaded in a second now take ten seconds. Fans kick on at high speed. Laptops become hot. Applications that used to pop up now leave you sitting there, watching a spinning beach ball rotate as it takes thirty or more seconds to load. This leaves the user asking "What's going on???"
 
Since MacOS 10.4 (Tiger), the operating system includes a pesky little process named "mds," which stands for meta data server. When this process becomes active, it can use nearly all your CPU power, put a heavy load on the drives, and hog so many resources it leaves other applications waiting.....and waiting......and waiting.
 
The mds process is used primarily by Spotlight and Time Machine, but a few other consumer apps can also use it. When mds goes into full indexing mode, it starts indexing everything it's allowed to on every drive, and in the case of Time Machine, it can't be stopped by normal user commands. Spotlight and Time Machine use the mds process, to index different things. If a user attempts to control Spotlight indexing alone, they may very well find that the problems still persist for what seem to be inexplicable reasons.
 
The end result is exactly as we described in the first paragraph.
 
SpotOff is a Spotlight and Time Machine meta data server (mds) controller that allows a user to activate and de-activate mds indexing on a Mac OS X system. Spot-O-Meter is an application available with SpotOff or as a free download (see below) that displays indexing activity via an easy to use interface.
 
It is not uncommon for users to experience the following symptoms when mds has “run amok”:
 
    - Applications that normally complete quickly now take much longer...sometimes as much as four times longer!
    
    - Web access slows down considerably.
    
    - Laptops may become hotter than normal, often kicking on fans at high speed
    
    - Games may become “jerky” due to CPU cycles being taken away from them.
    
    - Videos, either online or on DVD seem to have unexplainable pauses in them.
    
    - Battery consumption on laptops seems to degrade at a much higher rate than normal.
 
When indexing is intense, mds demands a considerable amount of CPU and I/O resources, which are in turn taken away from any other applications running on the system.  We’ve seen situations where the mds process may consistently use between 50% to 95% of the computing power of a system for hours on end!
 
SpotOff 2 allows a user to to do the following to bring mds indexing under control:
 
    - Disable and re-enable mds indexing by suspending and resuming it
 
    - Unloading and re-loading the mds process itself
 
    - Provide Time Machine control that is specific to mds indexing
 
Each of these tactics has it’s own advantages and disadvantages, which are described in the users manual. If indexing is suspended or the mds process is unloaded, it will remain that way, even between reboots. Indexing can now be brought under control, and users can allow it to occur when it’s convenient, rather than occurring while you're using the system.
 
If you have some critical work to do, or you’re going to do something and you don’t want to be bothered by the delays mds indexing can cause, SpotOff 2 may be the solution you’ve been waiting for. If you suspect you’re suffering from some of the side effects of mds indexing but aren’t sure, you can find out by downloading the FREE copy of Spot-O-Meter which can tell you if and when mds indexing is occurring.
 
NOTE: SpotOff 2 requires administrative access to use, whereas Spot-O-Meter 2 and Spot-O-Meter Mini do not.
 
 
Tech Support Note: The packaged bundle of SpotOff 2 with Spot-O-Meter  2 and Spot-O-Meter Mini for Mac OS X is fully supported by SCSC, however the free download of Spot-O-Meter 2 and Spot-O-Meter Mini for Mac OS X is not. There is, however, very little that can go wrong with either Spot-O-Meter versions.
 
The following two images show SpotOff 2 and the standard version of Spot-O-Meter 2  in use. In the first image, mds indexing is fairly intense (yellow zone) as indicated by Spot-O-Meter and SpotOff indicates that indexing is enabled (green light on the stoplight). In the second image, SpotOff has suspended mds indexing as indicated by the red stop light, and Spot-O-Meter 2 is showing no activity at all. SpofOff has successfully allowed the user to run their system at full speed without any mds intrusion!
