Subject: Load Test in Progress
Sender: owner-freebsd-alpha@FreeBSD.ORG
Precedence: bulk
X-Loop: FreeBSD.org

I am running, overnight, a load test on the PW 433au.  It is equipped with
512MB of RAM and 2MB of L2 (L3?) cache.

The test consists of 512 instances of st.c, all against a 128MB partition
on the only disk in the system.

It started with LA climbing to about 220.xx, and gradually declining to
7.84 (?!).  The funny thing is that there is considerable physical I/O
going on.

St.c simply seeks at random in the file/device given and reads 4KB from it
(it knows to do many other evil things).

I would have thought that FreeBSD kernel would have completely cached the
128MB.

Response to the keyboard and network stays reasonably good, considering the
load.  A 2xP6-200 machine typically goes on vacation at this load.

So, this looks real good, but some questions remain.  I will leave the test
running overnight.  If it is still alive, I'll add some nasty netwok
traffic to it.

Great Job! and thanx for all this ongoing help!

Simon
