UNC Chapel Hill libraries has allocated 8 VMs for testing Fedora performance.
| Parameter | Value | Notes |
|---|---|---|
| Clustered? | No | run as single node (a node from cluster w/larger disk) |
| Processing hardware | 2 Cores | Intel(R) Xeon(R) CPU E5-2690 @ 2.90GHz |
| Operating system | Ubuntu 13.10 | GNU/Linux 3.11.0-12-generic x86_64 |
| Memory | 2048 MB | only setting JVM max, 4GB real memory per server |
| Allocated Storage | 200GB | this persistence area /data is ext4 (/ partition is 12GB) |
| Persistence I/O | 106 MB/s | Is a certain level of throughput to disk an important part of the test? |
| Network I/O | 95MB/s | This is particularly important for clustered operation. |
