Hi all,
I built squid using SSL-bump. In addition, squid also authenticates users with active directory. The hardware is openstack virtual. os is centos8.1. There is one CPU. The memory is 16GB. The hard disk is SSD 200GB.
I'm thinking of load testing with Apache Jmeter in this environment.
I don't know the standard, so the test stops and I am in trouble.
How many simultaneous connection sessions?
How many requests per minute?
Help me.
thank you,
Kitamura

Eliezer's answer covers that already, so I will skip here.

This is "unknown" - as far as I am aware none has published numbers
recently about it. There are a lot of factors in the network traffic and
your servers internal state (eg the RNG engine) that multiply up to
cause varying amounts of delay - plus the volatile nature of this
feature set itself month by month changes the effects or relevance of
each factor.
So numbers from me today will be wrong in a few weeks, or may be wrong
for your network already. All that we can be sure of is that there is
extra work needed by Squid thus "slower" than plain-text HTTP is to be
expected.
For planning the consideration is just to be aware that the numbers we
can give you (for plain-text) will be over-estimates of capacity for
SSL-Bump traffic and allow some margins. Once you have an install
running you can test and measure the actual numbers for your traffic.
