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

    The JVM was running on machines built before people dreamed of clock speeds measured in gigahertz; there is no real "minimum". – Wooble Jul 09 '12 at 13:12
  • Definitely that computer has the _minimum specs_ to run a jvm. Java was launched when much weaker systems were being used. The slowdown depends on what your program is actually doing. – Tudor Jul 09 '12 at 13:12
  • try launching an app giving it 768 mb of ram on the machine shown above :) – Andrzej Bobak Jul 09 '12 at 13:14

    The "JVM" you are talking about is not the JVM we're talking about. Java 1.0 JVM is not even the same ballpark as today's Java. And anyway, a minumum is only relevant to printing "Hello, World". Everything beyond that depends on the app you are running. Eclipse is a Java app, guess what's the minimum to run it? – Marko Topolnik Jul 09 '12 at 13:17
  • The smaller the computer, the harder you will have to work to get your program to fit. IMHO its worth spending a few more $ to save yourself hours/days of work. Personally I wouldn't buy anything less than 4 GB these days, and an i3 is probably the minimum process I would buy. (In fact this is what I bought for my "TV" just to watch videos on) – Peter Lawrey Jul 09 '12 at 13:18
  • What's a basic Windows box worth these days, anyway? $200? – Marko Topolnik Jul 09 '12 at 13:20
  • The problem is that if I stay only in the application of the company and no longer use the computer for other purposes, yes, the system can stand quietly, but.. there are times when one has nothing to do, these are times when I check my email, enter the messenger, among other things, but I can not use it in parallel (my stuff / stuff company). – Filipe Manuel Jul 09 '12 at 13:22

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

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)

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

Java System requirements

If you have any other questions feel free to ask.
