 Posted: Tue Oct 24, 2006 7:02 pm Post subject: Higher CPU usage.BT related?Is this normal? |
 |
|
I have noted an heavy increase in CPU usage after launching a BT donwload of mor of 3Gb.
I'm using the last 2.81CVS but I have noted this behaviour in 2.80 CVS too.
Usually my CPU load is something between 8 and 25%. Curently moves between 15 and 99% ... There is no hashing.Perhaps am I not used with BT? Is this a normal behaviour?
Thanks |

Please shutdown all GUIs and do not use HTML and Telnet,
do you see the high CPU as well?

I have killed mlnet cause he has occupied more than 300megs in 14Hours.
It seems there is a big memleak around.
For your propose test to be done being useful I need for my client to reach normal activity again.
Note, The problem has started being huge when we have started downloading the Zod image thru BT.
I have perception of the problem when the web-interface has started not respionding, (GUI has gived feedback for a while than he has stoped too)...
FC-6-i386-DVD.iso (3525195776 bytes) / ISO 9660 CD-ROM filesystem data 'FC/6 i386 DVD ' (bootable)
from tracker..
http://torrent.linux.duke.edu:6969/announce
try from:
http://torrent.fedoraproject.org/
ANother bug? ->
I have also noted a little detail while launching mlnet from commandline..here is a piece of the first output:
| Code: | | 2006/10/25 13:16:59 [cCO] max_opened_connections 250, total_files 95, max_concurrent_downloads 50, !!files 0 |
But I have set max_xoncurrent downloads to 100!! I dont' understand why it keeps the default of 50!! |

I have about 1 mbyte/sec of meamleak at the moemnt... I have disabled BT and the leak has stopped imediately!!!!!!!(I have the killed mlnet cause the mlnet has about 133megs).
The issue is surely about the Bt plugin!!! |

I have tried cacellig the Bt download, closing the plugin, relaunched the plugin..re started the download from the tracker.(I have changed BT-identity of client to "default" but I thing it is not important).
At start I have noted again a memory grow... it reached about 90megs in few seconds but then it has fallen down and memory seems stabilized around 66megs.
Now the activity seems stabilized and the CPU usage keep being around 98% continusly.
But the mlnet occupies only 66 megs and seems working better.
At the moment webinterface responds very slowly (usable but it's ridicusly slow cause I am in local network).
It's deterministic after BT donwld start working hard the webinterface stops responding and CPU usage became 99%.

OOPS I have noted that ocaml veersion is 3.08.3 .. have I to had use 3.09 ? Could it be the core of the problem? I'm sorry for this oversight. |

The upload is also jumping beetween 5 and 12Kbyte/sec.
Sometimes the memory exploades again from 66 to 90(and more) emgs, and immediately falls down again to 66.
I'm going to change the ocaml version just now. |

I setup a MLDonkey in a clean dir to test download of the same torrent.
2h uptime, 70 kb/s medium download, 50MB RAM usage.

Ok, what about your CPU usage? I have changed (just now) to a core compiled on another debian box and I have a better CPU usage .. the average is about 50%, but stay low for some time (20%) and then rise to 99% for another piece of time, it's jumping continuosly from low to high... but I think it is normal as far as webinterface keep being responsive.
While the CPU load icrease the memory consumption grows to 70/80 megs and the falls down to 55 again.
But it seems
The webinterface is performing better ..it is more responsive.
My conclusion is that by compiling with 3.09.3 compiler has solved something.. but could this the original problem for real? Just for curiosity.
But I like to wait 1 hour first to jump to conclusion about the current core!.
Thanks for your support
My PC has a p3 700 with 320megs 120GigaHD |

Very low, nothing compared to your experience.

My core has started again peforming badly.
He has raised memory consumptio, webinterface was unusable, but I have tried sancho and I have sucesdully set a lower number of BT upload slots, this has improved the cpu usage and I have regained my webinterface  .
Tomorrow I'll try a fresh installation by pushing into the trash the old configs and starting from scratch.
Perhaps , I'll do a new fresh compilation with 3.09.3 compiled on the same box.
Cheers
About the connestion issue? |

Please post content of following options:
- max_upload_slots
- BT-max_bt_uploaders
- BT-max_uploaders_per_torrent

max upload slot=4
I have changed the BT settings a bunch of times lookin' for the problem I have tried for the
- BT-max_bt_uploaders 3
- BT-max_uploaders_per_torrent 3
- BT-max_bt_uploaders 2
- BT-max_uploaders_per_torrent 2
- BT-max_bt_uploaders 1
- BT-max_uploaders_per_torrent 1
Only one time I have set for mistake BT per torrent>max bt uploders ..but I hae immediatly corrected this. |
