What is the most serious performance problem?

In RFC 55, this http server seems to have perfomance problem as a http server

It still has poor performance characteristics

What is the most serious performance problem?
I think this sever creates one actor per one connection. I think that way is good for perfomance in terms of concurrent process of connections.

The HTTP parser does a bunch of things that you shouldn't do if you care about performance. A large number of which are in the Pony Performance Cheatsheet as "don't do's".

That's where you would want to start.

The existing parser uses error has control flow. Definitely not good for performance.

It also uses buffered.Reader to parse http payloads spanning > 1 tcp packet. In this process it copies all the bytes of the payload. I already have a few ideas on how to tackle those problems.

@SeanTAllen
Thank you for teaching me the Pony Performance Cheatsheet! I will start reading it!

@mfelsche
Thank you for teaching me one cause of performance problems! I also want to think about it.
