Build.sh release and installation on Centris660AV has finished
without any problem.

Centris660AV's onboard mc0 works. I don't see Warning nor Error
anymore, but my Centris660AV runs very slowly. For example,

1) ftp get comp.tgz from local ftp server, it says;
>     23656203 bytes recieved in 00:45 (511.35KB/s)
                     real time is 02:48 (140.81KB/s)

C660AV ticks slowly like as '030 Macs. I moved Centris660AV's HDD
to Quadra610 ('040 25MHz, 68MB-RAM, same as Centris660AV) for
comparing them.

                     real time is 00:38.35 (616.85KB/s)
       Quadra610 ticks correctly.
       Around 600KB/s is reasonable for 25MHz '040s in my network.

2) #time tar -xzf comp.tgz -C /

C660AV: 124.7u 343.7s 29:20.08 26.6% 0+0k 90+33775io 0pf+0w
             real time 36:47.88 <--!!

Qua610: 116.1u 290.3s 11:33.14 58.6% 0+0k 115+33781io 17pf+0w
             real time 11:33.73

I can't beleave Centris660AV gets 36min for "tar comp.tgz".
Is AV model so slow?

Thanks,
