I'm using fossil on a fs mirror device and speed seems
quite good. My network is 100M though.
Perhaps fs is responsible for your performance problem,
your requests go through yet another user-level file system.
If that's a problem for you, I may do some measures and tuning
to help locate the problem, just let me know.

Mmm, the disks are scsi (segate baracuda's on
an Tekram (NCR) controller)
What was strange was the slow speed of the mkfs | mkext.
The machines are 400Mhz PII and a 350Mhz PII connected
by 10Mbps ether so perhaps its just a sign of my ancient kit.
Anyway it works, and I shall be trying it for real as
when I get my venti server and DSL connection going.
Anyone any opinions which scripts in in /bin/services I
can safely copy to /bin/alt.services to run on /alt.net
(the internet) - I want to be able to connect to my
cpu & fs servers over the net but not get hacked (if possible :-)

I think those are normal. Do you have DMA turned on?
cat /dev/sdC0/ctl and make sure that the dmactl number
is not zero.
