I'm not sure if this is the right list to post to but,

I have run some test on the newer kernel for Linux using supersmack.

the test is a complete sale transaction.

the results for kernel 2.2 are:

sale_process starting with 100 clients
Query Barrel Report for client sale_process
connect: max=3458ms  min=3ms avg= 2132ms from 100 clients 
Query_type	num_queries	max_time	min_time	q_per_s
ins_address	100000		15		0		878.68
ins_buyer	100000		22		0		878.68
ins_order	100000		106		0		878.68
ins_unlock	100000		23		0		878.68


the results for 2.4 kernel are:

sale_process starting with 100 clients
Query Barrel Report for client sale_process
connect: max=167ms  min=3ms avg= 47ms from 100 clients 
Query_type	num_queries	max_time	min_time	q_per_s
ins_address	100000		63		0		937.27
ins_buyer	100000		87		0		937.27
ins_order	100000		101		0		937.27
ins_unlock	100000		88		0		937.27

This was run on a Dual PIII 700 512 RAM VaLinux 6.2 and SCSI-RAID

just to let others know about the improvements in the new kernels.
I think I can talk my boss into using the 2.4 kernel.
