After the most painful day where our UNIX team managed to delete all trace
of erlang and all the backups they took while upgrading the file systems to
Veritas I have some good news to report.

Growing a table from scratch at full transaction rate used to run at max 400
per second with pauses in the emulator of up to 7 seconds. With Veritas File
system it now runs at 2000 per second while another node is doing 100 remote
reads per second, and the longest read delay was 150mS.

UFS nil points!!

I am using Sun Netra t1s with 440MHz IIci SPARCs with just the two built in
