We plan to set up a variety of configurations (e.g. (solaris, oracle); (solaris, postgres), (linux, oracle), (linux, postgres) at MIT so we can get some performance benchmarks for .LRN. In the meantime, we strongly suggest that you plunk some money in increasing your RAM from the measly 2Gb. We should be able to identify the problem here, but you will not be able to support 30,000+ users on a Sun 280R with 2Gb RAM. It's not a "big Solaris server".
