This is quite noticable for me because my laptop has a fan in it that is off most of the time but which kicks in when CPU utilization is high. Reproducible: Always Steps to Reproduce: Type a bunch of text into the a form while running top. Actual Results: You will see that mozilla is using a huge amount of CPU while just accepting keystrokes into a form. Expected Results: Keyboard input takes minimal CPU.

well, this does happen. i did a little testing (all on windows), here are the results: typing in notepad: cpu hits 2% typing in textfield on IE: cpu hits 11% typing in textfield NOT in a table: cpu hits 50% typing in textfield in a table: cpu hits 89% really, really bad. but we all know where the real problem here is, but ill wait to say it untill i have profile data to prove it yet again. anthonyd

> we all know where the real problem here is 'cept me. I don't know what the real problem is. What is it? I'm curious. Is it the code that takes the events for the windows and figures out what piece of code actually needs to handle the event?

keeping this open for 0.9 because before buster left he checked in some layout code that will hopefully fix this. His fix especially addresses the problem when in tables. anthonyd (needing to re-test)
setting platform and os to all, even though thhis was first reported on linux, it exists everywhere. anthonyd
OS: Linux → All
Hardware: Other → All
moving this out to mozilla0.9.1 where we can spend a bit more time on this
Target Milestone: mozilla0.9 → mozilla0.9.1
Move this to mozilla0.9.2; anyone should feel free to help Tony out with this bug (unless he moves it back to 0.9.1). Ben Woodard--do you still see the cpu hit?
Target Milestone: mozilla0.9.1 → mozilla0.9.2
