Naturally, we have questions as to exactly how some of the infrastructure that we would like to be able to rely on works under particularly demanding scenarios. At the moment, the important question before us is how JCS' Lateral TCP Auxiliary Cache implements its put operations. Does it fork a thread per socket connection to lateral cache, does it do a broadcast to the subnet, does it do a multicast...? We received feedback from one gentleman earlier who uses the lateral cache with two machines. Has anyone used it with 10? 20? 30? Are there either known or anticipated issues with scaling to this level? Any insights based upon experience are greatly appreciated. Many thanks, Paul Snively
