Performance problem when rendering a very long template

[shengyi-yan]

Hi @yanick

A very good day to you.
I met a problem using Template-Mustache to render a very long template.
test_mustache.pl.txt
I uploaded the sample code which compares between Template-Mustache and mustache-simple.
mustache-simple always costs 0 second.
On my Macbook Pro, Template-Mustache cost 2 second, and in production which is in docker(2 core, 4G) it cost more than 20 seconds.
Is there any way or API to enhance the performance of rendering a long template?

Thanks!
