hi, Iâ€™m new to java, so please excuse my little knowledge in this field...
Iâ€™ve a situation that I need help from you guys
Weâ€™re running a java servlet on Apache Tomcat 4.1.18. Weâ€™ve like 60-100 clients accessing it through 15 (200k) Virtual Private Network connections; sometimes this 200k line has only one user occupying it, sometimes more than 8 users. The system provides some banking related services including querying the DB, uploading, downloading files and inserting some dataâ€¦.etc
When we launched the system couple of months ago the VRAM was 64MB, weâ€™ve expand it to 512MB couple of weeks ago because we were facing a major slowness in the performance of the system, this improved the performance a bit, but still there is a slowness that you canâ€™t ignore anyway.
Now regarding the clientâ€™s PCs, most of them are 3.0 GHz, 1.0GB RAM. And running J2SE 1.4 or 1.6.
My question is:
Is there anyway you I can do to get rid of this bothering slowness? Is it the system design? The connection bandwidth? The clientâ€™s PC specs? The VRAM? Anything else?
I appreciate your response, and thanks in advance.
