Hi Gireesh, For some reason I did not see your reply to me.
Raju's advice is one approach. It may be that you are using a feature that is slow in DHTML and we need to improve it. If profiling shows that is a problem, please report it as a bug. My advice pertains to using the OL Server as a deployment server. Your machine configuration is at the low end of what the typical developer uses. It seems possible to me that your server is being slowed down by running the OL Server (and Tomcat) and at the same time running your XAMPP services. You could look at your process monitor to see what the VM requirements of each of these is. If the total VM exceeds your actual RAM, you will get poor performance because of paging (which is typically very slow on low-end machines). By running the OL app as a SOLO app, you eliminate the need to run the OL Server and Tomcat, and your server can focus on just running your data back-end. Why would there be a difference between Flash and DHTML? Each of the target runtimes (swf8, swf10, DHTML) uses a different back-end in the server, and they may generate different memory patterns which may affect the server performance. Especially when competing with other servers on the same hardware.
