[win32] High CPU usage with low activity

[adagui]

Latest version (1.3.1) in Windows Server 2008 R2.

Only 400 torrents loaded. 2 are active (download 0KB/s, upload 50KB/s)

Deluge uses 53% CPU!!! (for comparison, utorrent only uses 1-2% cpu under this usage)

Running Deluge in classic mode.

System: 100mbit connection Core 2 Duo 4GB RAM

High CPU with low activity

[shnurapet]

I have ~20 torrents seeding (with ~130 paused tasks in list) in Fedora 14 x86_64, and the GUI is taking 100% CPU. Low when it starts. Seen it for two months now.

AMD Athlon64 X2 4200+ 2GB RAM

git master build plugins: Notifications, WebUI, BlackList?

The speed optimizations in #2184 should help this problem.

I have this problem with high cpu usage when deluge-gtk clients are connected. I'm running daemon, 1.3-stable git on Archlinux, Intel Atom N2800 @ 1.86GHz, 4GB RAM. 200 torrents started (seeding), 300 paused.

uname -a
Linux server 3.6.6-1-ck #1 SMP PREEMPT Mon Nov 5 14:59:40 EST 2012 x86_64 GNU/Linux

no clients connected (5-11% CPU usage)
PID USER      PR  NI  VIRT  RES  SHR S  %CPU %MEM     TIME+ COMMAND

1 client connected with deluge-gtk (50-70% CPU usage):
PID USER      PR  NI  VIRT  RES  SHR S  %CPU %MEM     TIME+ COMMAND           
26772 deluge     6   0  625m 280m 8340 S  57,0  7,1  15:45.62 deluged

2 clients connected with deluge-gtk:
PID USER      PR  NI  VIRT  RES  SHR S  %CPU %MEM     TIME+ COMMAND           
26772 deluge     6   0  625m 280m 8340 R 102,6  7,1  13:15.93 deluged           

This speed optimizations in ​#2184 didn't help with cpu usage

@miskoala That's because the fix is for GTK UI not daemon cpu usage.

[miskoala]

ok

and some more results for daemon cpu usage on my machine;

50-70% when all torrents (500) are paused and there is 1 client connected (gtk or web) 8% when all torrents (500) are paused and there is no client connected 3% when there is 0 torrents on list and 1 client connected 2,5% when there is 0 torrents on list and no client connected

sorry there is problem with enter, please delete above message :P

I forgot to mention I used libtorrent 0.16.x

With libtorrent 0.15.10 cpu usage for daemon is lower when there is 1 client connected: 25-45% (500 torrents on list)
