Website slowdowns

[lgromanowski]

Hmm, there're still some problems with redmine and slowdowns could appear :\
I've enabled additional logging (it'll be enabled till next weekend) an I hope it catch in what part of redmine there is an issue.

// EDIT: Known issue: ATOM feed from project activities in redmine is broken at this moment
// EDIT2: ATOM feed is fixed.

Ok, I got information from MyDevil admins - there are problems with server hardrive - current forums/blog/bugtracker performance problems are mostly caused by this. HDD will be switched to the working one soon (it'll be done without reboot).

Huh... a little scary that one drive failing on the server causes slowdowns? Don't they have things in raid?

But I'm not an expert. Thanks for the update!

Computers are not capable of intelligent heuristic analysis. It doesn't go, "Oh, this drive is being a bit slow at responding, we'll stop using it." When a drive fails on a RAID set up, the RAID does not indemnify against performance. It protects you (to a certain degree) from data loss.

Not true, going up the stack you can create a system that does just that.

Say for instance you are writing out data across disks like you would with raid, parity bits and all. You put a guaranteed of performance in place and disable disks that do not meet the threshold. Your hot-spares are activated and missing data filled back in automatically. (Yes, I've seen this in production.)
