That is when I get the worst experience - reading slashdot before I start the day. 70G would be much larger than any expected buffer cache. I would expect that would thrash your file buffer cache completely. Are the contents of the images changing daily? This might be interesting reading concerning this issue. Patches to rsync and benchmarks of it using posix_fadvise() with POSIX_FADV_DONTNEED and POSIX_FADV_NOREUSE flags to avoid file buffer cache thrash. http://lwn.net/Articles/449420/ Or you could simply move the start of the backup earlier so as to finish before you get to slashdot in the morning. :-) That is probably what I would do.

Has iceweasel (or maybe flash) gone single threaded
Over the last few weeks iceweasel has started to operate strangely. The whole application stops whilst trying to open a web page. you can't switch tabs. Sometimes it gets SO BAD that the entire desktop locks for a while. Am I the only person experiencing this. I suspect it has something to do with Javascript or Flash - Slashdot is a good candidate to cause this to happen - although it often appears from the status bar at the bottom that it is trying to fetch some advert info. -- Alan Chandler http://www.chandlerfamily.org.uk -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe.

Re: Has iceweasel (or maybe flash) gone single threaded
Yes, I mentioned that in recent days, and from what i observed, it's more of a javascript, because i didn't experience freezes on flash heavy websites.

I found the hangs as I call them annoying and left iceweasel for google-chrome-beta which does not have the problem.

Nothing changed recently. You were probably already aware of it. But you may be experiencing it recently now due to changes in behavior, such as compiling a kernel in the background while web browsing which will trigger this problem. Or something else.
