Hi,
I apologize for my stupid question but I am not Linux specialist.
Is there some recommendation for using 32bit java (and APR) on 64bit RedHat?
It is not a stupid question. Proof : I have the same question. :-)
If you allow me to hijack your post, my question is :
If my server has a 64-bit capable CPU, a 64-bit Linux O.S., and 8 GB of RAM,
and I have a tomcat which runs only one or two small webapps, and is unlikely to ever need
more than e.g. 1 GB of RAM,
is there any advantage (or inconvenient) in running this Tomcat in a 64-bit (or
32-bit) JVM ?
From previous posts on this list, I gather that basically the only advantage of using a
64-bit JVM, is that one can allocate more than 2-3 GB of RAM to the JVM.
But on the other hand, for the same workload, a 64-bit JVM will use a significantly larger
amount of RAM, without immediate benefits. True/false ?
So for the above Tomcat, I would use less resources, without sacrificing performance, by
running it in a 32-bit JVM. True/false ?
And if for some other Java application on the same server, I needed more than 2 GB or RAM,
I could always run that one in a separate 64-bit JVM. True/false ?
