It's pretty interesting that at least three people all got exactly
150kB/s on vastly different machines, both real and virtual. Maybe the
number comes from some tick frequency?

Hello 9fans,
I just got a used 3 button USB mouse (IBM-M-U35) which is giving me grief
on a fresh 9pi image (board rev 0xe firmware rev: 1427481988). The mouse
works fine plugged into Debian and OS X machines, but on 9pi, moving the
mouse causes the cursor to jump erratically around the screen,
Thanks Anthony.
I bet if you re-run the same test twice in a
row, you’re going to see dramatically improved
performance.
I try to re-run ‘iostats md5sum /386/9pcf’.
Read result is very fast.
first read result is 152KB/s.
second read result is 232MB/s.
Your write performance in that test
Thanks Aram.
I have spent some time
debugging this, but unfortunately, I couldn't find the root cause, and
I just stopped using fossil.
I tried to measure performance effect by replacement of component.
1) mbr or GRUB
2) pbs or pbslba
3) sdata or sdvirtio (sdvirtio is imported from 9legacy)
I too see this, and feel, no proof, that things used to be better. I.e. the
first time I read a file from venti it it very, very slow. subsequent reads
from the ram cache are quick.
I think venti used to be faster a few years ago. maybe another effect of this
is the boot time seems slower than
Hello!
imho placing fossil, venti, isect, bloom and swap on single drive is bad
idea.
As written in in http://plan9.bell-labs.com/sys/doc/venti/venti.html - The
prototype Venti server is implemented for the Plan 9 operating system in
about 10,000 lines of C. The server runs on a dedicated dual

I've just made some measurements when reading a file:

How many times do you time it on each machine?

Maybe ten times. The results are always the same ~5%.
Also, I restarted vacfs between each
Yes, I'm pretty sure it's not related to Fossil, since it happens with
vacfs as well.
Also, Venti was pretty much unchanged during the last few years.
I suspected it was related to the lock change on 2013-09-19.

It was the effect of the ram caches that prompted the question.
