I am currently setup with Kamailio 5.1 on an AWS t2.micro as a SIP300 LCR solution with
a http_query call to an external resource (c# .NetCore app for LRN dip and MySQL Route
choices) to get the contacts string, tag it to the Contact header an send 300.
Its been a while since I have performance tested on SIP and It was SIPp.
- Is http_query a bad choice for performance. Is KEMI better?
- Are there any better free apps than SIPp?
- Has anyone got cps stats for a SIP300 only Kamailio instance on AWS
- Is AWS a bad choice for prime time LCR. Any gory stories?

As long as you perform the queries in a properly asynchronous manner,
i.e. using http_async_client, not necessarily. But yes, HTTP queries are
by nature bureaucratic, since they evolve the establishment of a new
connection socket, etc. Doing something more inline is always better.
- Are there any better free apps than SIPp?
sipp is the leading FOSS tool for this. There are a variety of
commercial ones.

That's a meaningless question; way, way, way too many variables.
- Is AWS a bad choice for prime time LCR. Any gory
stories?
No, it's not a bad choice.

I am assuming the function http_query in kamailio utils is async. Is it not?

It is not async, and is furthermore deprecated in 5.x.
You may want to have a look at:
https://kamailio.org/docs/modules/5.1.x/modules/http_client.html
https://kamailio.org/docs/modules/5.1.x/modules/http_async_client.html
But in general, if you're looking to squeeze maximum performance for a
dialer type workload, no, pound-for-pound, HTTP is not the way to go.
