Poor performance in largish files
Every keystroke results in a delay of a few seconds in large files (2000+ lines) making the plugin unusable.

Let me know how I can debug more!
I'm running into the same issue, except with longer lag and smaller files (running Doom). According to the profiler, most of my CPU time is spent in php-syntax-propertize-function.
Following through a little more, it may be that it's spending a lot of time trying to syntax highlight areas of code that have been commented out (because they are unused). I got some performance improvement by removing these sections (not a permanent solution as the code is not mine). Is there any way of turning off e.g. php--syntax-propertize-quotes-in-comment?
Is there any way of turning off e.g.
php--syntax-propertize-quotes-in-comment?
Like this?
