Reduce CPU, IO activity and UDP transmissions (peak+avg)

[synctext]

Tribler uses 30% average CPU usage in idle of v6.1 on a single i7 core.

Dependancy: insight in performance #6 and fix inefficiency # 1 (this ticket is repurposed).

Old Mac Book Pro performance (idle, no downloads, no seeding):
55% average CPU usage on older 2.2GHz Intel core 2 duo (with 99% peaks)
360 IO operations/second at peak
309 network packets transmissions/second at peak

Most expensive GUI operation:
Viewing a subscribed channel with thousands of torrents.
It takes 15seconds to respond and CPU goes to 130-140% range

Can you confirm the cpu usage for the current devel branch?
Currently Tribler is behaving very nicely at my laptop, nicely skipping a lot of Bloomfilters (+/- 80%) resulting in a cpu load of 0-5%

with debugging disabled?

[NielsZeilemaker]

I guess he's running a released version, hence it would have debugging disabled.

I was asking you, I'm running devel's HEAD with debug enabled and I get much more than that, around 30% most of the time. Also, around 25.9% skip and 58.4% reuse.

[NielsZeilemaker]

Just wait a bit, the skip will only work after receiving all data.

Its been running for around couple hours now. I will wait a couple more.

Ok, I'm just under 80% now and CPU around 10% just for the python process. (debug enabled)

Always happy to test the latest branch, looking at Jenkins OSX build...
Got stuck: #166 .

[whirm]

I got to ~85% skip at home. @synctext you can test again now that #166 is closed.

Congrats!

No more 110+% CPU usage!

You manage to create a Tribler which does not kick the fan into action.
CPU usage is significantly reduced. Guess there is further room for improvements on IO usage, but that is no longer a high priority.

idle (no download/upload) on my linuxliteos (ubuntu trusty based),
tribler cpu usage is always 40%-100%
