I am doing benchmarking of several algorithms involving read/write to disk.
As Windows provides some cache features, sometimes I get results like these :
- first run of the algorithm : 200 seconds
- second run of the algorithm : 90 seconds
- third run of the algorithm : 87 seconds
After a reboot :
- first run of the algorithm : 202 seconds again
It is rather simple to disable write cache (http://support.microsoft.com/kb/259716), but how to totally disable disk read cache?
