Re: best performances for the java 6 JRE: linux or solaris?

Today, my application runs well on a SOLARIS 5.9 V240, and the IT
proposed me to either buy a new V240 or to get a linux/opteron.
I need to use the CPU for XML processing, that is the bottleneck of my
application (I have seen the linux solution is 2.8GHz, 2x2 procs...
therefore I though it was really faster).
Before sending my answer, I want to know this group point of view
PROS:
faster => I need CPU to highly process XML
cheaper => IT said it is 2 times cheaper
CONS:
migration
Migration of Java code should be painless.
The application uses the
CPU mainly for XML processing, and it is the bottleneck of it.
The application uses a lot more than the CPU. The CPU is likely not the
bottleneck at all.
XML processing is subject to inefficiency in the software. Depending on what
software you use, who wrote it and how they wrote it, you can have dramatic
difference in speed, several orders of magnitude, on the same machine.
I asked how much speed difference is important to you. No answer. I asked
how important reliability and uptime are. No answer. I asked if you
considered O.S. alternatives. No answer. Same with all the questions I
asked. These and other questions are very relevant, and speed may be the
least of your concerns.
Even if speed is a concern, it likely will make the least difference which
computer runs the application. You could get thousands of times faster speed
by rewriting an inefficient algorithm, at best some fractional improvement by
picking a different CPU.
You tell your I.T. department that initial cost ia only a fraction of Total
Cost of Ownership (TCO), and to start thinking with their big brains.
