The concurrency of query subsystem is somewhat lower in 2.6.
This is most evident on Windows, but affect Linux and Solaris as well.
Example queries that show the slowdown in throughput (ops/s):
| Platform and version | Query 1 | Query 2 | Query 3 |
|---|---|---|---|
| Red Hat 2.4.8 | 2160.56090475 | 2009.83491425 | 1159.27502825 |
| Red Hat master | 1924.269752 | 1792.2990925 | 447.8258245 |
