"max outstanding disk writes reached"?

Postby simonbcn » Fri Mar 19, 2010 3:56 pm

Deluge 1.2.1
Ubuntu 9.04 32 bits

What's the meaning of this error in my deluged.log?

Code: Select all

[DEBUG] alertmanager:115 performance_alert: Trainspotting_JMBD: performance warning: max outstanding disk writes reached

It basically means what it says. libtorrent tries to be nice and throttles it's writes to disk or how much data it will hold in a buffer before flushing to disk. This has the side-effect of slowing down some your downloads. This is all in an effort to keep the memory usage down and file integrity up. That being said, these settings can be adjusted, but they aren't exposed in Deluge. The new libtorrent 0.15 version improves on how it handles these types of situations and the defaults should work better.

And what version of Deluge will use this new version of libtorrent?

You can use it with 1.2 or the upcoming 1.3.

I will wait for deluge 1.3.

I have downloaded and compiled libtorrent 0.15 and deluge 1.2.2, but deluge 1.2.2 can't run with libtorrent 0.15! :(

I have wasted time and effort for nothing!

Why do you say this if it's not true!? :?:

i would have thought it to be more sensible to compile against 1.3 but i am surprised its not backward compatible.
