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...
