Critical JavaScript Performance Issues for Settings > Websites

We have a Piwik instance running for an enterprise customer and we’re experiencing heavy client-side performance issues for the Settings > Websites page. This is based on Chrome, but we experience this issue in all browsers.

When I request this page, it first says:
You currently have access to 0 websites.

After a few seconds, this changes to:
You currently have access to 699 websites.

After this change, Chrome literally freezes. After some time, the “Long running script / Kill pages” popup appears. I click “Wait”.

I read All sites tab Dashboard very slow loading but this is clearly a client-side issue. Please don’t link to the Archive Cron - this is running perfectly for us.

I collected a timeline profile with Chrome (version 39.0.2171.71 m).
I attached the export: here.

These are the facts:

We are currently on Piwik 2.8.3. Any help highly appreciated. It’s really painful to maintain websites at the moment.

(I don’t know why the links don’t really work in this editor - sorry.)

Hi there,

I think you want this feature: Show paging in the screen 'Manage websites' to easily manage thousands of websites · Issue #3838 · matomo-org/piwik · GitHub

Hi Matt! Thanks for your reply! So this means that it’s currently default that it takes that long (> 1 minute) if I have around 700 pages?
