javascript - Front end profiling -

-

i trying open source project determine cause of front end slowdown.

i seeing long load times on end, full page load takes 10-15 seconds, button clicks can take 30 seconds respond, etc.

service running on local network.

the load on server quite low (0.1) i'm positive issue rendering, dom processing, , whatever other code running.

curl shows extremely fast response, know issue front end.

they cannot reproduce on end, can consistently reproduce on end.

what else should profiled besides javascript? tools should into?

os debian 8, browsers firefox , chromium.

thanks!

if need profile mobile performance, use chrome on dev machine tool, run app on mobile device.
