Hi, i just came across this: https://bugzilla.mozilla.org/show_bug.cgi?id=508427
The advice is to set layout.frame_rate to a lower value than the default 60 (-1). The same applies to Thunderbird. dtruss shows for 30sec: // layout.frame_rate = 24 CALL COUNT getsockname 1 open 1 doorfs 2 getuid 2 mmap 2 open64 2 statvfs64 2 unlink 2 close 3 fstat64 4 lwp_kill 18 lwp_sigmask 18 setcontext 18 access 35 fcntl 38 ioctl 73 gtime 74 stat64 116 lseek 160 send 419 llseek 1355 writev 3256 getpid 3257 lwp_mutex_timedlock 3765 lwp_mutex_unlock 3765 write 8997 read 11844 yield 12086 pollsys 27330 recvmsg 28980 lwp_park 44725 clock_gettime 154470 // layout.frame_rate = -1 CALL COUNT mkdir 1 open64 1 recv 1 unlink 1 getsockname 2 ioctl 2 statvfs64 2 fdsync 3 gtime 3 rename 3 access 4 doorfs 4 fstat64 4 getuid 4 open 4 close 5 yield 12 lwp_kill 16 lwp_sigmask 16 setcontext 16 fcntl 51 munmap 92 mmap 100 stat64 115 send 419 llseek 1399 memcntl 2597 getpid 2615 lwp_mutex_timedlock 3838 lwp_mutex_unlock 3838 write 8761 read 11410 writev 36870 lwp_park 44045 clock_gettime 74407 pollsys 94750 recvmsg 130168 It seems to lower pollsys count as advertized (if I understood well). How does this look for you?
