From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux 2.2.17 i686; en-US; 0.7) Gecko/20010120 BuildID: own build from 0.7 source (no options) When just moving mouse over mozilla (in any mode or any page) it takes about 50% of precessor time (800MHz AMD) (In Netscape 4.75 it is less than 4%). So there is something seriously wrong in the system level. Reproducible: Always Steps to Reproduce: 1. start mozilla and top 2. move mouse over mozilla and watch CPU user prosentage Actual Results: it shows nerly 50% Expected Results: in netscape 4.75 less tham 4% Even when you do absolutely nothing, one process (the main process I guess) is looping over poll that returns immediatly (look by strace). I guess the poll should sleep until there is an event (like mouse move).
Works ok here with my own build from the tip on Linux. Reporter: can you be more specific? Is this occurring on any specific web pages? Is it only in the browser (what about mail/news)? My CPU usage somes barely registers when I hover.
Adding perf keyword.
I notice larger CPU spikes when moving the mouse between the rendering window space and the URL bar. But moving to/from the throbber, it's nearly neglible.
xk: that shows up as up to 10-15% cpu usage here. Reporter: I'm missing the obvious. You're compiling with no options which means you are building a debug, non-optimised build. Try --disable-debug and --enable-optimize for a start. Read the Unix Build Configurator at http://webtools.mozilla.org/build/config.cgi to create a .mozconfig file.
Via email: From: <firstname.lastname@example.org> Ok, thanks for that. I'll try it and tell you what happened. But could you tell me where the debug was going so that I could delete it from taking disk space. **Please ensure that ALL messages are entered via bugzilla. Thanks. The solution to your problem is to 'make -f client.mk clean' then rebuild with the wanted options.
without more detailed information this bug is not going to be useful to developers. That we are CPU intensive is a known issue.

yeah, best rebuild, maybe even try a new profile as well. I self build on linux too and never saw it that bad.
