Since I am doing client side Java, performance is a non issue. Each user ("session") has it's own VM and own CPU. On the server side, I use sticky session replicate nothing "design". So 6 app (SoA) servers each have their own cache (of their user's queries). The CPU is far from the bottleneck, it hardly budges. ( the 1st thing that maxes out is the dual gigabit NICs. Next is SQL DB server. Map splits... I wish I get to that as a problem. In any case, number of columns on a table is few). .V Clinton Begin wrote: >If I recall correctly, commons-collections fast Map implementations >are only better for reading, and could possibly be even slower for >writing.
