Am I missing something? Why worry? Benchmark it and find out. I like Jmeter, but maybe someone else on the list can recommend a better tool. As it stands, you have not described anything that would require a blocking execute method in your action. From what you've stated, you will likely see some disk IO contention. Again, benchmarking will tell you what your system can handle, and whether or not you need to optimize. Why optimize unless you're sure you need to. And, if you're going to optimize, it's nice to have a way to measure. -Dave - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: DownloadAction and concurrent threads
I see no reason why the DownloadAction would be programmed to synchronize against anything, especially for the whole download, that would be a real showstopper! If you don't use instance variables, and only read from a database (with a connection for each download) or a filesystem, you wouldn't need to synchronize either.
