Re: Benchmarking

I finally got some time to do DragonFly; the (somewhat suprising) 
results can be seen here: http://geri.cc.fer.hr/~ivoras/osbench/osbench.sxc

It seems that DF could do a lot better but there's something holding it 
back (especially in the web CMS test). I got a lot of 'too many database 
connections' errors, like the db server doesn't get the chance to free 
the connection when it's closed so that the next client can use it. 
Also, under DF a bug in a program was reveiled: an object was not 
protected by a mutex/lock like it should be. It is interesting that the 
bug had not manifested on all the other tested systems, but on DF it was 
consistent and frequent (maybe the process-switching rate in DF is higher?).

(This is work in progress, and I will create a world-readable report in 
PDF or HTML when it's finished. Until then, the above document will be 
the only published data).
