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).
