SAP's benchmark was run most recently against an HP Blade, 2-processor, 8-core, 16-thread, 48-GB RAM, using Microsoft Server 2008 EE & Microsoft SQL Server 2008.

My most recent Web application benchmark was run against a 2006 ERA Power 5, 1-processor, 1-core, 1-thread, 1-GB RAM, under IBM i.

My comparisons are pretty rough because the applications are not precisely the same, but it appears that my IBM i server is outputting about 50% more dynamically generated web pages, and performing more database transactions.

Your way of benchmarking is ... interesting. Compare apples to apples.

Write your IBM i Code in ILE C, use full commitment control and
journalling for everything.
Write your Windows Code in C/Win32, set the SQL DB Recovery Mode to "Full".

Then, do your benchmark again.

What you're currently doing is benchmarking a light-weight web
application against a fully-featured framework. What this tells us is
that a leight-weight application is faster than one running inside a
big framework - which is hardly news.

Also, consider that your Power 5 machine costs the same amount of
money as the HP Blade including OS licensing.
