zenrpc generate very slow

[digitive]

Hi
We love zenrpc.
We just experienced the zenrpc code generator being very slow. We have a small project which about 10 methods in 2 files, which takes zenrpc more than 1 minutes to generate. And the CPU usage are very high during the generating process.

@digitive could you please check new v2 version? We've made some improvements in generator.

We are using:

github.com/semrush/zenrpc/v2 v2.1.0 h1:a6jKcimSTS2u/FkAg8qXkAcplBC9vEAInl7aQY47u7g=
github.com/semrush/zenrpc/v2 v2.1.0/go.mod h1:+o94fyVC+TvYuT5ULLyBmql+ezicEFKtsieIXSeWBqg=

Macbook Pro with SSD and CPU:

 % sysctl -n machdep.cpu.brand_string
Intel(R) Core(TM) i7-6567U CPU @ 3.30GHz

Generating 15 services in ~60 seconds:

@smyrman are you using heavy imports like s3?
How can we reproduce this issue? Could you provide test project?

Hi, sorry for the late reply.

Unfortunately we do not have a reproduce code we can share for the 15 services example. At the moment, I also do not have the time to setup a reproduce test repo, but if I find the time later, I will let you know. I can mention the different services reside in different packages, so each run of zenrpc for one service in particular generally run for 14 - 24 sec depending on the service.

PS! I have no connection to @digitive. I just saw there where no update on this issue and wanted to contribute to show which numbers we are seeing in our organization to see if it's relatable.
