[wellylug] Java 32 Bit/ Java 64 Bit Performance

[Gerald.Roehrbein]

Hello Daniel,

that's a real world application written by a third party company. 

I was asked to analyze the reasons for the bad performance because my
client and the developer thought the reason is Oracle because in their
development environment the software performs much better in a client
server environment with less and smaller CPU's, less network bandwidth
between client and server and less IO performance at database level.

The only reason I found was the difference between a full 32 Bit driven
environment and the 64/32 Bit mixed environment.

I agree that the developer should change his programming strategies.
They use dynamic arrays but they use container class libraries they
developed in the past which could not not be changed easily.

To have a full benchmark would allow to show the differences in detail
and this would be better as to use a self made benchmark software.


kind regards
Gerald
