What is the minimum configuration to run the JVM?

Question

What is the minimum configuration to run the JVM?
The computer I work has the following settings:

MS Windows XP Professional SP3
Intel Celeron 2.26GHz CPU, 959MB RAM, VIA/S3G UniChrome Pro IGP

Using a Java-based program and I think that is causing this latency, besides having to use Internet Explorer to access the Intranet (which only allows the use of IE). So I wonder what the minimum configuration to run the JVM, so that my computer can be replaced.

From now on,
Thank you.

Sorry for bad english

Answer 1

The more RAM the better, processor and gpu are irrelevant. My workstation has 8 GB of RAM and it's ok for running a tomcat server, database server, firefox with dev add-ons (it can sometimes use around 1 GB of ram), Eclipse and some other tools.

The more RAM you have the more you can give to the apps executed in jvm (-xmx and -xms options)

Answer 2

depends on what system and what version of jdk see http://www.java.com/en/download/help/sysreq.xml

for Windows XP 128mb

Answer 3

Well first you must consider the version of JVM you want to run, as for any other software the more you advance of version the more resources it "eats" therefore supposing you're on JVM 7 consider this table from the Oracle website
