[Mojolicious] Re: Mojolicious application to show markdown as slides

[mimosinnet]

Thanks a lot Jan!

I have enjoyed your code, discovering I have a lot to learn ;-) It has been 
very useful seeing your use of Mojo::Path and the way you read files and 
directories. I will try this in my code. I will also try to understand the 
more idiomatic parts of your code :D

Cheers!

Well I think it's fantastic and I know I'll use it all the time!

I certainly cannot speak to the impact it will have on Mojo core.

Hi,

Not sure if this is interesting, but I have a competing project for 
rendering markdown files. Haven't gotten around to complete it...

[Mojolicious] Mojo performance

['Andrey Khozov' via Mojolicious]

Hello there,

I noticed with strace that a simple Hello World mojo lite app (perl -Ilib/
-Mojo -E 'a("/" => {text => "test\n"})->start' daemon) has one of the most
common syscall is gettimeofday.

% time seconds  usecs/call callserrors syscall
-- --- --- - - 
 39.950.000614   0  5610   write
 22.120.000340   0 11238   gettimeofday

  5.920.91   0 11220   epoll_wait
  5.660.87   0  5666   read

These calls are used here:
https://github.com/kraih/mojo/blob/bbc6e0c21480d2594f518e85ad331bfa795eb430/lib/Mojolicious.pm#L119
and
https://github.com/kraih/mojo/blob/bbc6e0c21480d2594f518e85ad331bfa795eb430/lib/Mojolicious/Controller.pm#L207.
And
they are needed only in the debug mode, but used even in production mode,
where log level is info and above.

Without this extra Time::HiRes::gettimeofday calls performance of this app
can be increased to 10% (from 1100rps to 1230rps on my laptop).

I can't create a PR because a simple check for $log->is_level('debug')
breaks the tests t/mojolicious/app.t and other, where app->log->level is
debug, but $log->is_level('debug') return false. (I think this is due
HARNESS_IS_VERBOSE environment variable)

So if anyone can help with PR it would be nice.
