RE: more good iseries news

["jt" <jt@xxxxxx>]

Rick,

I had these same questions, exactly...  Especially the last line of the
article.

The only major software issues I *know* of is the effect of tiered pricing
on packages.  IIRC, the article said most of their stuff was custom code,
though.

IOW, I don't get it, at all...

Maybe they've had some bad experience, which they mis-identified as a
problem of multi-processors, because I've never heard of any (other than
*slightly* less gained for each processor added)...

| Jim,

| Thanks for the post.  Would anyone like to discuss the meaning of the

| them down?

| The issue of maxing out on capacity was faced early on. Passer said
| stress tests were performed at the IBM iSeries headquarters, in
| Rochester, Minnesota. From that, it was determined that adding a
| second processor would be "an easy fix." The next round of increasing
| capacity is more complicated. "After two CPUs in the iSeries," Passer
| explained, "the application server has too much overhead and doesn't
| really offer a big advantage over multiple application server
| instances. In all cases, it means more CPUs, but there are major
| software issues one gets bogged down with."
