 Posted: Wed Jan 24, 2007 3:55 am Post subject: mldonkey responding slowly and using 100% process |
 |
|
Just today when I tried to log on with the web interface it took forever for the page to log on. Even telnet localhost 4000 is slow in responding. It's also taking up 100% CPU process, this isn't so much a problem because it's a dual CPU machine but it's just annoying and I know it's not supposed to take up that much process.
For example, if I telnet in... then auth user password ... then ?? it'll hang about 10-20 seconds or so then display the output and that's quite irritating.
I checked in mlnet.log but I didn't find anything unusual, then again I wouldn't really know what is unusual.

ok... Recompiled with ./configure --disable-bittorrent and everything seems to be OK. Not the ideal solution as I would like to use the network but I don't really use it too much anyway.
update:
It's doing it again without bittorrent. Ugh!

please..
recompile in this way to enable profiling:
http://mldonkey.sourceforge.net/ProfilingMldonkey
There is little guide there,
and then post the otuput to developers...
It seems the problem triggers himself in mysterious ways, I have tried with normal distros at the moment but I have a biger CPU usage but no-system-suicide.
This test could be useful. |

Once I generate the output where do I send it to?

Just to make sure I did it correctly. You're suppose to set DEVFLAGSOPT=-S after ./configure and before make? And how long should I keep it running?

yes, I have understood in this way..
plus I have understood you can write all in a single line:
DEVFLAGSOPT=-S make
and simply push enter.
Here has worked.(but I could be wrong)
I suppose you can launch an \"evil BT/ed2k download\" and left the program run for a significant time (about half an hour,or one hour) in the problematic state. |

@dirtyboy
P.s: Just for curiosity.
Can anyone(with the CPU/BT problem) here try to disable GeoIP database(remove the link from webinfos and delete the GeopIp file from .mldonkey directory ) and try again with BT... does this "Mambo Jambo" help reducing the load ?
@Spiralvoice
a friend of mine has reported that by analyzing mldonkey activity (using strace) he has noted that GeoIP database(Geoip.dat) file is read tons of times.
Perhaps this has caused the raising in "wa" (top) which I have noted in the past with top (raised disk activity).
He has pointed that in 6 minutes his core has read more than 100Megs form the GeopIP database file. (GeoIP file is something around 1Meg big).
IMHO
P.s:I think that an otption to fully cache in memory the GeoIP file or to Page the file in memory could be a good point to reduce disk activity.
/IMHO |

Afair geoip data is only used when data is displayed by some GUI.
Did your friend connect to MLDonkey using some GUI?
Does MLDonkey read from geoip.dat when no GUI is connected?

Tomorrow I'll met my friend and I'll ask him about this detail.
P.s. I have reminds about him using the Sancho Gui (usually). |

Perhaps he's using ip_blocking_countries? |

Hm, this might indeed be true.
Since 2007/01/17 I am also using this option and I am seeing an
an increase in CPU usage since then. But I am not so sure about
whether this really increased CPU because on 2007/01/25 the
swarming_block_selection_algorithm = 3-patch was committed
which increased CPU as well on slower machine (here AMD K6 300).
This patch is now removed from CVS, which lowered CPU here.
Now I cleaned option ip_blocking_countries, tomorrow I will
check if this had an impact on the system.
