I recently switched from 0.9.4.1 to the trunk / 0.9.8 and noticed that opeing the pref dialog got a lot slower, by about a factor of 10. In 0.9.4.1, it took less than a second. Now, it takes, when I'm lucky 1.5 - 2 second, much longer otherwise. 3-4s are pretty common, in one case it took about 10s to open the dialog! I have never seen this with 0.9.4.1. Note that I am using a fast machine (Athlon 1.2GHz, 1 GB RAM). sairuh's perf test don't show anything like that. The results (1-2s on that machine) seem unchanged since long.
Do you have a large prefs.js file? Is there anything possibly unique about your prefs.js file? Do you observe the same perf hit with a new profile?
My pref.js is 44k large and has a lot of Mailnews accounts. (This is no different from 0.9.4.1.) A new profile seems a bit faster. But maybe it's just normal derivation. I don't build the help extension (giving me an error on the console).
i haven't seen the pref window open take as long as 10sec [ouch!]. but the current performance has been kinda up'n'down of late. my results [and test methodology] are at http://mozilla.org/quality/perf/preferences/index.html
