[orca-list] many cpu wakeups with orca

[Halim Sahin <halim sahin t-online de>]

Hi,

I have checked the cpu on my laptop with powertop and found the following:


Cn                Avg residency       P-states (frequencies)
C0 (cpu running)        (66.3%)         1400 Mhz     0.0%
polling           0.0ms ( 0.0%)         1200 Mhz     0.0%
C1                0.1ms (33.7%)         1000 Mhz     0.0%
C2                0.0ms ( 0.0%)          700 Mhz     0.0%
                                         500 Mhz   100.0%

Wakeups-from-idle per second : 5387.2   interval: 5.0s
no ACPI power usage estimate available

Top causes for wakeups:
  99.6% (5429.0)            python : schedule_hrtimeout_range (hrtimer_wakeup)
   0.2% (  9.4)       <interrupt> : uhci_hcd:usb1, yenta, eth0, 0000:02:00.0
   0.2% (  8.8)       <interrupt> : pata_via
   0.0% (  1.0)           rt61pci : queue_delayed_work (delayed_work_timer_fn)
   0.0% (  1.0)     <kernel core> : neigh_table_init_no_netlink (neigh_periodic_
   0.0% (  0.8)   hald-addon-stor : schedule_hrtimeout_range (hrtimer_wakeup)
   0.0% (  0.4)       gvfsd-trash : schedule_hrtimeout_range (hrtimer_wakeup)

This means that the cpu can't never save power and runs always with 1400 mhz.

I have stopped all other python processes.

Orca is 2.26.1 under ubuntu.
Any chance to fix this?
The current setup is not very usable on laptops.
It will discharge the batery very fast.
Any ideas?
