We've done some comparisons of RAM (Lucene RAMDirectory) vs. Flash-SSD vs. conventional harddrives. We've seen significant improvements for Flash-SSDs over harddrives, but less for RAM over Flash-SSDs. For our setup (Linux, Flash-SSDs, 4 core Xeon, simple searches, 37GB index, 10M documents, ~70 fields), the CPU seems to be the bottleneck. Testing with a commodity Flash-SSD might be worth trying before going all-out with the RAM-based systems. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
