Hi Jiri, Thanks for the link it clears up better what you and Thomas are saying. You both have been extreemly helpful. What you and Thomas need to understand is the typical developer will not ask the questions that I do. To me a profiler and static code analysis tools are as important as a IDE for productivity and assuring quality.
I did run visualvm on two other windows PC's (Windows Xp Sp2 and Windows 2000 prof sp4) and did not get the error that I got for the instrumentation profiler (the sampler did not generate any errors). Thanks for your time I am trying to get different functional groups interested in using visualvm as we upgrade to jdk 1.6.0_7 and above so they get the visualvm profiler. I am just trying to do what noone else has done and get a system response time via lan under 1 millisecond with inexpensive hardware and open source software (Tomcat/JBoss) and need a way to find bottlenecks using a tool that can measure down to millisecond or below. I am/was at 3-4 milliseconds measure at the client using JAX-WS and just last night figured out where my remaining bottleneck (using visualvm and help from the Tomcat group) might be to achieve my goals. Just imagine the size of a data center if vendors/developers could create solutions that responded under a microsecond (I have code that used to be under 1 nanosecond but now around 5 microsends with 3 tier caching). Depending upon the network technology you could serve up whole countries with that type of capability using open source like Tomcat no less! Just need the 200Gbps networks the universities have here in the US :-) Best Regards, -Tony --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
