Browser Slowness when Model Building


Has anyone else noticed that after 15-30 minutes of model building activity (opening modules, opening lists, updating formulas, opening split views, toggling from blueprint to module view, etc.) that browser tabs slow down and stop responding, and has to be restarted.

Been an issue for a few weeks now.

Hardware and software:

- PC: Lenovo T16

- CPU: 12th Gen Intel(R) Core(TM) i7-1270P 2.20 GHz

- RAM: 32.0 GB (31.7 GB usable)

- Chrome Version 122.0.6261.94 (Official Build) (64-bit)

- Windows 11 Pro Version 22H2

Root cause analysis:

  • Persists between machine restarts
  • Affecting multiple Anaplan tenants, model builders, all using Chrome and Windows
  • Has been happening for a few weeks now
  • Issue is immediately resolved if you **** the browser tab and open a new tab, at which point users can pick back up where they left off without issue

Based on root cause analysis, wondering if there's some sort of memory leak affecting Anaplan on Chrome, but surprised it hasn't been raised yet.

Reaching out here to gauge if this is affecting anyone else, so that we know we're not crazy.

    Maybe try building a new model and do some basic model building activities. Do you still encounter the same issues? I am also using chrome and not experience any slowness or lags while using Anaplan.
