Memory Tuning and Context Switches

[Andrew Elliott]

Hi again,

 

We've just upgraded to 12GB of ram and are still experiencing extremely high
context switches, in some cases, 45000 (vmstat 3 100).

 

Does anyone have a link to a technical doc that has information specifically
dealing with context switching and RAM optimization?

 

I'm thinking that I just need to give more cpu time to kswapd.  Comments?

 

Thanks.
