Hi all,

Executing the LTP "mem01" VM test shows a huge time discrepancy between 2.4.20 and 2.6.3. Under 2.4.20 the total time is around 5 seconds, while under 2.6.3 the system seems to hang for nearly a minute.

Where in particular should I start to look to see if it's a configuration/environment issue or a real problem? What other information would be helpful to know?


2.6 must start writeout, does it? Can you post vmstat 1 logs for each kernel?
