I did some disk I/O and CPU benchmarks, including bonnie++, hdparm, nbench, unixbench, dbench, tiotest. I haven't done any network/memory testing yet.
Here is a rough comparison of E7500, E7501 and the ServerWorks Chipset:
==========================================================================
| Benchmark | E7500E7501 | ServerWorks | GrandChampion LE |
==========================================================================
| Nbench (integer index) | 33.47 | 38.78 | 10.61 |
==========================================================================
| Nbench (floating-point index) | 27.03 | 32.05 | 20.87 |
==========================================================================
| Unixbench index | 329 | 349.5 | 141.6 |
==========================================================================
| Hdparm -t | 70.33MB/s | 73.73MB/s | 46.04MB/s |
==========================================================================
| Hdparm -T | 512MB/s | 673.68MB/s | 673.68MB/s |
==========================================================================
| Tiobench (write) | 41.2MB/s | 42.09MB/s | 44.37MB/s |
==========================================================================
| Tiobench (random write) | 7.03MB/s | 9.73MB/s | 10.87MB/s |
==========================================================================
