Re: SLOW Performance: OpenLDAP on Linux and IBM Dual Xeon?

["Gary Allen (ldap)" <gvldap@corvu.com>]

I'm running OpenLDAP with RedHat ES 3 on a Dell 1600SC Dual Xeon.  I 
have no issues with speed (as you note).  However, I don't have a 
similar IBM box to do comparisons.

First, are your tests valid to each-other?  Same version of OpenLDAP?  
Same data backend?

Second, you might want to look at differences in the architecture.  I 
would immediately be suspicious of your Disk setup, and overall non-LDAP 
load differences.  Perhaps check for Kernel or driver updates from IBM.

Finally, as is commonly mentioned in this list, you may want to consider 
upgrading to the Latest OpenLDAP sources, and if you are on recent 
OpenLDAP sources, what version?

Thank you,
Gary Allen
