Trac Fails to return results on some changesets

[mgorbach@…]

I have several changesets on my site macfusionapp.org/trac which trac 0.11 beta 2 fails to display at all. It waits a little while and then I get a "page not found" message in Safari. An older version of trac (previous stable) seemed to show these changesets fine, although it took a while.
Nothing interesting appears in the log. It stops with a message saying its getting the chrome.

An older version of trac (previous stable) seemed to show these changesets fine, although it took a while.

If it "took a while" with 0.10-stable, chances are that it now takes "too long" for your Safari browser, which reaches its time out.

See #7029.

Ok, #7029 had apparently nothing to do with slower changeset rendering, so I'll paste here what I already said on that topic:

A "100% load for about 30-45 second" is unfortunately not uncommon with lengthy pages like big changesets now that they're rendered with Genshi. There are ongoing efforts to speed things up at the Genshi level, including a ​GSoC proposal.

Please also report the memory usage on server side while Trac is rendering those changesets, as there are known memory issues (#6614) and if the server is swapping, the rendering will be even slower.
