The only way to know for sure would be to create a test program and try it.

Having said that:  Java seems much faster on my little Pentium 2 400 than it does on 
our z900 under z/OS 1.3 at 480 mips (two processors).  Both are with Java 1.3.1.  I 
have not really done a benchmark, but Java programs definitely start up faster, and 
finish sooner on the P2.

Subject: Performance question


Hello all,

a customer of mine in Germany is faced with a choice:

Run a Webserver on a MS NT/W2K platform (Websphere) or

the same, but on a z/Linux platform running under z/VM (IFL).

The application is (will be) CPU intensive with extensive Java usage.

I do not have MIPS rating for the IFL engine.

I am hearing a lot of "it will run better on the MS/Intel platform
because the application will be CPU bound" ... etc.

Could anyone give me a "rule of thumb" as to what would be the

performance considerations vis a vis the two platforms.

Regards,
