Extremely slow syntax analysis for JS in PhpStorm 9.0

I've updated ide to 9.0 and got big performance degradation with js-files. After small editing of file a syntax analysis is running about 12 seconds. In 8.0 it was running less then 2 sec. The same project (huge project with many php- and js-files), the same config.
What exactly happens on "syntax analysis" stage? Which settings can I disable to increase performance? I already tried to reset IDE settings, reset project settings, disable all inspections, but it doesn't influence "syntax analysis" stage. The problem is present in default build and with bundled JDK.

Hi there,

Please submit new ticket with such file attached (you can make such attachment visible for devs only if necessary) to WebStorm's Issue Tracker (All JS/CSS/HTML tickets go there anyway as it's a home project for such functionality).

But yes (from personal observation and seeing similar tickets for actual WebStorm) -- JS analysis became slower in last 2 major releases especially in more-or-less big files.
