RE: [WEB400] FRCA-Fast Response Cache Accelerator any benefit while running CGI apps?

["Bob Cozzi" <cozzi@xxxxxxxxx>]

The number of CGI jobs is almost unimportant in your case. The number
indicates the number of simultaneous "enter key" from browser uses. If your
user count exceeds that current number, they will have a short wait and then
get their chance to run. I run the RPGIV.com website which gets thousands of
hits each day on just 7 to 10 "jobs".

I don't know anything about FRCA, but traditionally serving HTML pages out
of the IFS is what people do; serving them out of a source file member is
perfectly acceptable and is actually faster than IFS-based HTML pages. If
you convert your IFS to *TYPE2 then the performance gap between source
members and IFS is narrowed.

Most of the time there bottleneck in CGI applications is long running
database activity, but also there is the issue of bandwidth. If you're on a
screwy network configuration, you may have problems, if the way you're using
your CGI service program (assuming you're using CGILIB or CGIDEV2) you can
create bottle necks. But the main place to look is in your RPG IV code. Most
people do not write well performing RPG IV code, but many believe they do.

Subject: [WEB400] FRCA-Fast Response Cache Accelerator any benefit while
running CGI apps?

My apologies for the continuous questions but now that I'm running Apache, I
feel like a kid in a candy store and am looking to maximize my CGI
performance.  The documentation is useful but end user experience is almost
always much more informative.

This question is about the FRCA.  My CGI apps are basically RPG database
intensive programs that don't make much use of the IFS.  About the only IFS
references I use is for the graphics (icons and pictures) I store on the IFS
so my CGI apps can reference them.

In this case, does using FRCA add any benefit?


Also, I see there are options to specify the min and max number of CGI jobs.
The default is 40.  I cannot find any documentation on recommended values
based on my system size.
