Sue,

Here is a follow-up on the VMS XFC success story I sent you earlier this
week.   After an additional two days of running, the Read Hit Rate is
now 98%!!!   Actually, if you do the division in floating point, it is
98.48%.
Everyone is simply loving it!

Sue,

At a client's site, they have an AlphaServer 1000A which, besides
everything else, collects data from 50 or so custom
data-entry terminals on the factory floor.   This data tracks which
employee performs which operation on which customer's job.   It is used
both for job & cost tracking and traceability.

At lunch and at end of shift, the accumulated data is used to update a
huge RMS indexed file with four keys.   A week
ago, this update took over ten minutes of solid disk activity.

Last weekend, I upgraded VMS from v7.2-1 to v7.3-2. This was the first
time I had the opportunity to use the Extended File Cache, and the
results looked promising, but we didn't have enough memory to
effectively use it. So yesterday, I increased the memory on the 1000A
from 320MB to 832MB.   WOW!!!   That was money well spent!

Today's noon update finished in only ten SECONDS instead of ten 
minutes!
We are seeing 95% hit rates where the
percentage of Read QIOs is 96%.  The XFC is a big win!

Thank you all very much for making me look good.   All the users are
commenting on how much faster everything
is now.   The client feels that VMS support and update service is worth
every penny.   All their Windows boxes just get slower with every
update, while VMS gets faster!
