I can tell you that I tried running a PHP application (Help Desk) on our
270 (only 2 users) and it was so slow as to be completely unusable.
Didn't try it on our 720 (at the time) as it was supporting about 150
users. We replaced that with a new 8203-E4A and I may give it a try
when I have time. As far as speed.... jobs that used to take 60-90
minutes now run in 5-8 minutes.
The new machines are reasonably priced, use less power, generate less
heat, and have a very low HWMA & SWMA cost. Well worth it.

James,
With respect to the PHP application, they can realistically expect a 50x
performance increase by going with a new system vs. something like a 5%
increase by upgrading DISK and RAM. PHP is a CPU intensive workload.

Subject: Upgrade existing machine or buy new?
Hi everyone,
I have a customer that has a 9406-170 with 256MB main storage and
25.770GB
disk storage. This system is fine for the 25 or so concurrent users
most
of the time. Now we are going to install a web application using Zend.
When we run our web app on that system, it is too slow. The customer is
considering a new System i for this reason. What would be the best use
of
their money, buy a new System i or upgrade the RAM and add more disk?
They currently are as near as makes no difference to 100% disk usage.
The
daily close and backup is taking about 40 minutes longer than they would
like. They are on v5r3m0. An important software factor when
considering
v6 and beyond is that they are heavy users of WRKQRY and that isn't
going
to change.
Best suggestions?
James Rich
if you want to understand why that is, there are many good books on
the design of operating systems. please pass them along to redmond
when you're done reading them :)
