This is due to the huge amount of Javascript executed for the left-hand pane, and it's a dupe of various Javascript engine speedup bugs (e.g. bug #203448). *** This bug has been marked as a duplicate of 203448 ***

Philip: are you sure it's a dupe of a known bug? In general case it's hard to tell without a testcase and/or profiling information. If you're able to point to the bug that causes the slowdown on this page, please mark the bug as a duplicate of that specific bug and not of the tracker bug.
Hmm... This is very odd. Before, I was seeing huge amounts of array assignment Javascript in the source for the left-hand pane, but now I don't see any of it. My reply and dupe was based on the fact that the slowdown is just cumulative due to the huge amount of Javascript to execute (several pages of it), but I can't see any of it now, yet I'm still getting the same slowdown. Reopening. :-(
