Subject Re: [OT] best hardware config for Tomcat
Date Fri, 20 Jun 2003 12:34:34 GMT
Thanks for the reply. I had never thought of the RAID sub system. My
situation is that there is no one I know to advice me in this regard and my
company can't affod any highly paid consultancy. That is why asked a
question like this here.
    Another question. Do Tomcat a requires a faster hard disk. The
application uses JSP and Servlets only. No HTML pages are used and it
generates some PDF and Excel files. It also serves some small images files
from local hard disk. I think Tomcat will cache these images. Now my concern
is  whether Tomcat's performance increases by faster DDR RAM.

regards Antony
