Of > this, e17 is 4/sec, hence it would be nice to find the culprit and (if > possible) remove it. if the mouse causes 4 interrupts/sec - this probably cause mouse events? thus x wakeups and then e wakeups to get the events. those 4 could be: 1. something polling - what, i don't know, but you will need to strace and/or debug and find out. as already pointed out some modules like to poll - but most of them its in the 1 per second or multiple seconds between polls (except cpufreq. 2. it could be the result of an x client changing a property etc etc. like a titlebar etc. see #1 - need to debug. 3. every 10 secs e pings x clients to see if they are alive if they say they do the netwm ping protocol, but if you have enough windows these pings won't happen at the same time so they will be spread out based on when the window came up. i share your desire to reduce this, though 4/sec is really minimal when you think about it :) > Regards, > > Alec > > > > > ------------------------------------------------------------------------- > This SF.net email is sponsored by DB2 Express > Download DB2 Express C - the FREE version of DB2 express and take > control of your XML.
