Scaling for performance : Results and more to come

[Trevor Warren <trevorwarren@yahoo.com>]

Fellas,

 Thanks for your help. The results for the same are as
below. Averaged at about 100+ writes/sec(See TPS).
This setup is DB(4.2.52 + patches) and OpenLdap
2.2.12. for results see below.....

 During one such test with the same config i had
openldap crash with following msg:

"[root@blade2 openldap]# ../../libexec/slapd -d0
slapd: ch_malloc.c:122: ch_calloc: Assertion `0'
failed.
slapd: ch_malloc.c:122: ch_calloc: Assertion `0'
failed.
slapd: modify.c:957: slap_mods_opattrs: Assertion
`mod->sml_mod.sm_nvalues[0].bv_val' failed.
slapd: modify.c:957: slap_mods_opattrs: Assertion
