Figuring out if the server just responds slowly

This might be a bit more /r/sysadmin question but as we all know it's always the network and you need to prove otherwise :)

Wondering if there are tools that I could run against packet capture from a server and from that figure out if the server is actually responding slowly to requests. This would be of course better to check from application logs, but the software is not managed by us and the people managing it don't seem to be that good with reading logs. They'll just tell us it's the network.

Wireshark can show round trip times for TCP sessions, but seems I can look only at a single session at a time.

Thanks!
