On Linux, it seems quite a bit from the numbers I've seen posted. On Windows it depends more on your app (i.e. lots of large static files will see the most). Haven't really seen many numbers for other O/Ss. About the only way to tell with your app is to try it and see ;-). > 2-how tomcat use it ? what else change in installation when we select to > use native library With the default config, Tomcat simply looks for the dll at startup, and if it finds it, then it uses it. If it doesn't, it falls back to the Java Connector. The rest of the install is identical, so later just deleting/renaming the dll will give you the same install as if you selected not to use it. > 3-in tomcat start-up application under start up tab ,there is a DropDown > box which asks about mode that tomcat will run > there are two modes ,1-JVM , -JAVA > is it true that > when we select JVM it uses JRE to run tomcat > When we use java it uses JDK to run tomcat ? > Not the best names, I'll grant you ;-). When you select JVM, the service loads the JVM into the service process via JNI, and runs Tomcat there. When you select JAVA, it spawns a seperate process that runs java.exe. Not sure how well JAVA is supported; I haven't tried to use it in a very long time. > > Thank you --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
