More test results for public. We ran my original query and found out that on 4 cores CPU: 1 thread test 8.2 bits 8.3 by 10..15% 4 threads 8.2. wins 8.3 by ~2% 8 threads 8.3 finally wins 8.2 by ~2% the same data set was affected during multi-threaded runs, but it's 100% cached from the disk. I guess we see the result of concurrent scans optimization in 8.3... -- Vlad
