Ask HN: What is an acceptable latency for a web load balancer?

We use an external company for network management. They've put a Citrix ADC load balancer in front of our web servers, which is also terminating TLS. I'm not sure if it was always like this (before I joined the company) but downloading a 1000 bytes file via HTTP takes ~15ms while the same file via HTTPS takes at least 110ms. The external company ignores this and claims that SSL termination is expensive. I can understand a few ms, but clearly 100ms is rubbish.

What do you think folks?
