VIP Slow response time

Hi,

Please see below for the answers.

From the same IP source, you have different connection delay if you connect with VS or without?

Ans: Yes that's correct. With VS response time is 5sec and without VS it is 2/3 sec.

Did you define any profile in LTM virtual server?

Ans: We have setup 2 VIP's(one is responding in 2/3sec and another is responding in 5sec) for sftp services in two differnet load blancers. For both VIP's we are using client protocol profile as tcp and server protocol profile as (use client profile).

We also tested by changing these client/server protocol profile to tcp wan/lan optimized profiles respectively. but we didn't observe any difference.

Isn't it a DNS timeout depending of the client IP knowledge by the DNS server? Can you try by adding the IP address in your server hosts file to check if it is the cause?

Ans: we tried this by adding VIP address to monitoring server instead of VIP name, But response time still the same.
