30,000 requests in 10 seconds probably isn't normal traffic, but it could represent a sudden spike.
think of it another way, that's 3,000 requests per second. If we calculate that for a 10 hour period, it puts things in perspective 1000 req/sec * 60 sec/min = 60,000 req/min 60,000 req/min * 60 min/hr = 3,600,000 req/hr 3,600,000 req/hr * 10 hr = 36,000,000 req that means during normal work hours, the server would get 36 million requests. to handle that kind of traffic, first you have to have the bandwidth. There's an old performance article I wrote that's listed on tomcat's article section. read that and see if it helps peter On Jan 26, 2008 10:14 AM, Ali Ok <[EMAIL PROTECTED]> wrote: > Thanks David, > > I mean, if I make 30000 requests in a very short time (about 10 seconds); > Tomcat does not respond. > I read books, tutorials, faqs and threads at maling list about Tomcat > tuning.
