Hello Maxim,

I made some tests and definitely we cannot use in our product, it
takes too much time and resources. 

Tested on an EC m1.medium instance.

As you can see 50k hosts take more than one minute. That would be
acceptable if it weren't for the fact that it uses up a lot of CPU and
memory. Parsing the config seems to be the culprit here.

These where simple server blocks with self-signed certs just for

It would be awesome if there was some sort of compilation process for
the config parsing. It's too costly. Let's say you have a machine with
50k hosts, now you add another one and the machine gets a beating just
for adding this one.

Any comments on my test approach?
