Hello bill, More computers that more CPU? You see the cheapest production server that I have is a 2 CPU Intel Xeon 3.0Ghz HP-Compaq rack server with 2GB RAM. And this is a dedicated server running only J. :D My best one has 4 CPU Intel Xeon 3.0Ghz HP-Compaq rack server with 8GB ram but alas on this one J shares it with MS-SQL.
About memory management, if you would look in my C# J Session wrapper in http://www.jsoftware.com/jwiki/Guides/J_CSharp#head-657861bc638169ed65f08e52c7d641cce98bf758 , I make sure that unused J instances are released from memory. Actually, trivial J calls like sorting or picking are done the client and the servers are reserved for operations that would take more than a minute to complete. I basically decide which onesrun on the clients machine or which ones on the server during design. Still, can you elaborate more on your opinion on my case? I might learn something new. :) r/Alex P.S. Hong Kong airport is GREAT! FREE WiFi Internet Access! My flight is 6PM and I've been here since 11am and I've been surfing and playing Guild Wars all day! :D -----Original Message----- From: [EMAIL PROTECTED] on behalf of bill lam Sent: Fri 2/16/2007 11:16 PM To: General forum Subject: Re: [Jgeneral] J use of Multi CPU servers Alex Rufon wrote: > they need to execute a related service.

I found that jconsole application need 5 to 15 MB. So 24 J tasks already need about 15*24=360 MB. Having one J task for each request is not very scalable, it seems that you need more computers than more cpu. -- regards, bill ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
