[Derek Harris [:DerekH] - Dont need info. Last day 6/5/15]

Not nominating to block on this. This only occurs when the language page is first loaded after a fresh flash or reset. If the user goes forwards, and then backwards to the language page again, performance is normal.

This is an ugly performance indicator on first run. Can we take another look at prioritizing this? Also, is this the same as bug 1173145?

[Sam Foster [:sfoster] (he/him)]

Leaving need-info on myself to look into this once I have a local build again and the ability to profile it

[Sam Foster [:sfoster] (he/him)]

Have a WIP that seems to help here, but I want to get user timing instrumentation in there first so we have a baseline to compare to.

Ah, you're right and that bug has window and relevant discussion so lets pick this up there.
