This week's book giveaway is in the General Computing forum. We're giving away four copies of Arduino in Action and have Martin Evans, Joshua Noble, and Jordan Hochenbaum on-line! See this thread for details.
I have two flavours of jre installed one in linux box(64 bit) and another in XP(32 bit)..below is the output of java -version. I would like to understand what is the significance of word 'sharing' which is available in windows installed VM.
XP(32 bit) java version "1.6.0_10"
Java(TM) SE Runtime Environment (build 1.6.0_10-b33)
Java HotSpot(TM) Client VM (build 11.0-b15, mixed mode, sharing)
linux box(64 bit) java version "1.6.0_18"
Java(TM) SE Runtime Environment (build 1.6.0_18-b07)
Java HotSpot(TM) 64-Bit Server VM (build 16.0-b13, mixed mode)
Also can you please give me some pointers where to find any bugs(performance related) in the linux based VM versions.
The problem is that the application deployed on tomcat is becoming quite(ver very) slow as the number of users accessing the webapp start increasing and when it reaches 8 users it takes lot of time to service the request and also cpu utilization is 60 -100 % . I have started analyzing the problems, and any pointers would be greatly appreciated btw i came to know that tomcat they were using in production doesn't have any changes made in configuration other than heap size(rest all are defaults that comes when downloaded).
