Compilation of templates is VERY slow

[josefsabl]

Today I found out that the compilation is qutie slow for rather large email. I have an email layout with some Inky template elements and inside the content block of layout is one large table (1000 rows) that itself does not contain any Inky special elements. The comilation of one such e-mail takes 150 seconds. It means that it is 0.15 s per one row in the e-mail, that is VERY slow.

Hi,

this seems about right. Right now I do not have time or any ideas to make it reasonably faster. If you have got some ideas, feel free to offer them.

Now the problem worsens. Before the e-mail template was quite large. Now we ran into problems with quite simple template that easily matches one screen. One such e-mail takes ridiculous 2.5 s to process. I think that paquettg/php-html-parser is to blame. I tried to profile the template compilation and isolated the slowness in \PHPHtmlParser\Selector->seek() method which gets called 30 times and takes almost 2 seconds for one e-mail.
