This should be a blocker for at least 0.3, IMHO; the /people page can take upwards of 21 seconds to load: http://www.webpagetest.org/result/120501_9N_468F3/ We tried to address this a bit in bug 735867, but since we have the great problem of continually adding more awesome Mozilla Reps, page performance keeps spiraling.
On version 0.2.5 we pushed today the loading time is down to 16sec (13 sec for second view). Still needs work but it's definitely an improvement ;) http://www.webpagetest.org/result/120523_SG_ESD/
Here is a last run from version 0.2.5 of the website so we can compare results when we deploy 0.3 http://www.webpagetest.org/result/120730_3X_98C/
With remo release v0.3.4 we have caching in place and gradual load of reps. The page is fast now! :) Closing this one as fixed.
Verified FIXED: http://www.webpagetest.org/result/120904_ZF_ERX/ Nice work, guys!
