M11 layout is MUCH slower than M10. This is particularly noticable on OpenVMS, which is not the fastest platform for Mozilla in the first place, but its also very noticable on Linux. My OpenVMS build contains every M11 checkin to date (including today's). My Linux build id is 1999111108. Here's some samples times to load the M11 release notes page www.mozilla.org/projects/seamonkey/release-notes/m11.html OpenVMS Linux M10 4.5 sec 2.5 sec M11 127.0 sec 18.5 sec What's going on here? If I stop in the debugger, I see LOTS of reflow routines getting called. To my untrained eye it looks like they are being called recursively. Why is M11 so much worse than M10???? My Linux system is a 500MHz box. It should scream!!! With M11, the only thing screaming is me!!!!!

Marking as verified dup of 17325.

M12 is SIGNIFICANTLY better. As far as I'm concerned, you can close out this bug report.
