You are running on 10.2.0.x on a NUMA box.
Query second time around does NOT run faster although you would expect at least some blocks to be cached. When checking using a 10046 trace you see that the blocks are read from disk on all subsequent executions.
Due to this issue, the expected improvement due to caching is not occurring.
