LDAP Load Balancing Performance Problem

Hi guys...

 

 

I'm having a problem with an vitrual service load balancing LDAP requests... When i request directly to the servers the response is very fast but when i request via BIG-IP the responses are quite slow...

 

 

Any opinions?

 

 

Virtual Service Config...

 

 

service port: 389

 

 

protocol profile client: tcp

 

protocol profile server: tcp

 

address translation: enabled

 

port translation: enabled

 

 

no persistence

 

 

pool with two servers

 

 

Thanks in advance...

    You could capture tcpdumps of the slow query times through the virtual server and compare that with traces direct to the pool member. You could also try changing to a Performance L4 virtual server with a FastL4 profile.

    Problem solved... It was the reverse lookup DNS regarding the virtual service IP... There was no entry for the IP in question...
