On my side transmission.cgi and general performance problems remain
I have to check that one (transmission), as I don't really use that kind of downloading.

o.t.o.h. in -8 I had faster transfer speed to the asus (writing with almost 4mbyte/sec with vsftpd) than reading from the asus (reading with almost 3,5mbyte/sec with vsftpd)

now, in -10 it's the other way around:
uploading to the asus results in almost 3.5 mbyte/sec with vsftpd.
downloading from the asus results in almost 4.0 mbyte/sec with vsftpd.
(this is nice, as I download more from the asus as I upload.)

but yeah, the system is stable, but -8 seemed more stable.

OFFTOPIC:
However, I really like the work that has been done by oleg in -10 so I don't want to complain a lot about this.
Being a software developer/analyst myself I do know that some (middle) versions just don't cut it. The good thing about that is that the update which follows on that one is usually really really good. (but that one just hasn't been released yet )
(as you all may know off M$ Millenium.. (as a middle version, upgrade for win98, and to keep consumers satisfied for giving the great server2000 to the companies) boy that was crap, while it's successor (xp) was (and still is) really great.) and boy... now vista. (do I need to say more)... you can bet, the new windows (min-win) will be really great.
ONTOPIC:

Still, I don't think it's to far-fetched to make -10 as good as -8
