Most of the development happens on the Individual Dev's system " Windows 2000" While the deployment is on the Linux Box for final product integration /Load test Forget the web application with DB /Connection / .... A Single Simple JSP ( Hello world ) is taking longer on both browsers IE 6 /FireFox 3 >> both Windows 2000 and Java 1.5 are in the "no longer supported" When something is in Production it really gets pickles to upgrade the Jdk /OS , Realy worried .... :( With regards Karthik -----Original Message----- From: peter.crowth...@googlemail.com [mailto:peter.crowth...@googlemail.com] On Behalf Of Peter Crowther Sent: Wednesday, December 09, 2009 7:43 PM To: Tomcat Users List Subject: Re: deployed same TOMCAT 6.0.20 on Windows / Linux 2009/12/9 Karthik Nanjangude <karthik.nanjang...@xius-bcgi.com> > Same Tomcat 6.0.20 from > > > http://opensource.become.com/apache/tomcat/tomcat-6/v6.0.20/bin/apache-tomcat-6.0.20.zip > OK. > RAM is 2 GB on Linux on Windows is 1.5 GB > No extra applications are running when the same was executed > How much of that RAM is given to Tomcat in each case? > Machine details > > Windows 2000 > 4 CPU 2.66GHz > Service Pack 4 > OK.

As with all businesses, yours needs to trade off the expected cost of upgrade (including the disruption) with the expected cost of supporting the old versions. I'm not arguing with you - I still see the odd NT 4.0 box, and several Windows 98s ;-). - Peter --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
