[CentOS] Good value for /proc/sys/vm/min_free_kbytes

Hi,

 what would be a good value for

/proc/sys/vm/min_free_kbytes

 on a Dual-CPU EM64T System with 8 GB of memory. Kernel is
2.6.9-42.0.3.ELsmp. I know that the default might be a bit low.
Unfortunatelly the documentation is a bit weak in this area.

 We are experiencing responsiveness problems (and higher than expected
load) when the system is under combined memory+network+disk-IO stress.

Thanks
Martin
