OptimizationKit is tool, which include module named Prefetch. Short description is below.
1. OPTIMIZATIONKIT
It is tool (daemon) for making optimal work of Linux, according to parameters given in the configuration file. It allows to chagne CFS, CFQ, Deadline and Aticipatory scheduling parameters for task depending on configuration.
There are the results from the Nexuiz benchmark.
| Code: |
|--------------------------------------------------------------------------|
| Nexuiz 2.3 timedemo | CFS + CFQ | CFS + CFQ + OptimizationKit * |
|--------------------------------------------------------------------------|
| timedemo demos/demo2 | 41,395896833 fps | 41,460051233 fps |
|-----------------------|------------------|-------------------------------|
| timedemo demos/demo2 | 18,343223633 fps | 37,814504933 fps |
| + massive_intr 4 1000 | | |
|-----------------------|------------------|-------------------------------|
| timedemo demos/demo2 | 9,334974533 fps | 37,376611267 fps |
| + massive_intr 8 1000 | | |

OptimizationKit allows to use cgroups mechanism for 2.6.24 and above version of kernel. This mechanism allows to split users into groups, which allocates quantified system stocks.
2. PREFETCH
Prefetch is a tool, which makes the program start up time shorter. Preferch loads binary files and libraries from a hard drives, which becomes the buffer. Due to it first start up of program is faster.
There are the results of times of starts up on test machine.
| Code: |
|----------------------------------------------|
| starts up | OpenOffice 2.3 | Firefox 2 |
|----------------------------------------------|
| first start up | 12 seconds | 7 seconds |
|----------------------------------------------|
| second start up | 4 seconds | 4 seconds |
|----------------------------------------------|
| first start up | 8 seconds | 5 seconds |
| with prefetch | | |
|----------------------------------------------|

| Seems like the prefetch alone might not be worth it, but automatically setting up cgroups is kinda a nice feature. It'll be interesting if you can find more performance tricks to use... |
