Hello and please forgive me if I'm not in the right post group.
Our SMTP VS is just loadbalancing between two smtp server. I have tried a few parameters - like tcp-lan-optimized - but the time to get an answer from the smtp server through the Big IP LTM (through the VS_SMTP) is n times slower than the direct access to the server : would you have any idea of what could be implemented to have the same response time between the VS and the direct access to the server ?
Basic test, in dos command :
- telnet 25 takes 5 seconds to get the answer from the server
"220 smtp.name.com ESMTP Service (Lotus Domino Release 8.5.2FP1) ready"
- telnet 25 gives immediately the prompt "220 smtp...."
Thanks for any advice.
