If the slowness is caused 100% by load on your single machine then you may be able to reduce to response time although a tenfold increase is pretty optimistic. But a request time of this length I would look to your application as the primary culprit.
Does it have this response time for just a single request with 1 user on the system? If it does then clustering is unlikely to help you at all. With a load balancer or some other way of splitting the users clustering will reduce the number of users hitting a given machine and free up some processor and memory. It will not share the work of a single request accross multiple tomcats. My advice would be to profile your application first, work out where it is spending its time and if the response is good in a single user scenario then perhaps experiment with clustering. Ta Matt -----Original Message----- From: Michael Cardon [mailto:[EMAIL PROTECTED] Sent: 03 June 2004 01:10 To: Tomcat Users List Subject: Tomcat 5 clustering For the sake of this question, let me assume that I have an application running on one instance of Tomcat that takes 10 seconds to complete a client request. If I cluster 10 machines together does it help with the through-put, i.e. meaning it might take 1 second to complete the request now, or does it just make the session redundant in case of failure. Just wondering about which setup would serve me the best and be the fastest for our clients. Thanks for any input on this.
