I use Zimbra Desktop on my laptop. When running zdesktop server, which I'd really like to do all of the time, my CPU about 200 types a second. 49% of those wakeups are:
42.8% (120.5) java : futex_wait (hrtimer_wakeup)
It doesn't sound like much, but I've lost a bit of battery life. Is there a wake to keep the wakeups a bit lower?
ps: I use powertop to test my wakeups and estimated battery usage.
