Re: What happened to rpgenerationx.com? -- WEB400

Walden,

Nice numbers on your stress test!

It would be quite interesting to stress test the Relational-Web boat report
on your model 270, and compare it to your ASP equivalent.  Just let me know
if you'd like a copy to test.

I agree that testing a full application would be much more relevant than
testing a single program or script.  That would be a scenario in which
Relational-Web would really shine, exceptionally.

My program generated 24K of HTML while your ASP script generated 2K of HTML.
By adding another 72 records to your copy of the BOAT table, the HTML
streams would be comparable.

Another factor to consider is the CPU speed of your model 270 vs. my 170.
What is the processor feature on your server?

We ran a CPU bound RPG benchmark on a model 270-2250 and found it to be 17.5
times faster than my model 170, for example.
