During the SmartFoxServer testings we have run a set of benchmarks under stress conditions to measure the performance and stability of the server. To check the scalability we have also tested the software on a various range of hardware platforms and operating systems from a minimum of 24 hours to a maximum of 13 days.
Here are some of the results we've recorded:
| Test #1 | |
| Hardware: | Celeron 700Mhz, 256Mb ram (66Mhz bus) |
| Op. System: | Mandrake Linux 10 |
| Runtime: | Sun Client VM 1.4.05 |
| Test Settings: | 500 clients in 10 rooms sending 50 characters long messages every 6 sec. |
| Bandwidth used: | 3-4 Mbit/s |
| CPU occupied: | 75% |
| Notes: | No slowdowns detected, other servers running in the background such as Sendmail, Apache, MySQL 4. The test was run for 13 days. |
| Test #2 | |
| Hardware: | P4 2.0Ghz Notebook, 512 Mb ram |
| Op. System: | RedHat Linux FC 3.0 |
| Runtime: | Sun Server VM 1.4.06 |
| Test Settings: | 2500 clients in 50 rooms sending 40 characters long messages every 6 sec. |
| Bandwidth used: | 6-8 Mbit/s |
| CPU occupied: | 47% |
| Notes: | No slowdowns detected. Test was run for 5 days |
| Test #3 | |
| Hardware: | P4 2.0Ghz Notebook, 512 Mb ram |
| Op. System: | RedHat Linux FC 3.0 |
| Runtime: | Sun Server VM 1.4.06 |
| Test Settings: | 1000 clients in 50 rooms sending 150 characters long messages every 3 sec. |
| Bandwidth used: | 16-20 Mbit/s |
| CPU occupied: | 70% |
| Notes: | No slowdowns detected. Test was run for 5 days. We used those unreal settings to stress the bandwidth aspect of the test. |
| Test #4 | |
| Hardware: | P4 3.0Ghz w/ HT, 1Gb ram |
| Op. System: | Windows XP sp2 |
| Runtime: | Sun Client VM 1.4.04 |
| Test Settings: | 2500 clients in 50 rooms sending 40 characters long messages every 6 sec. |
| Bandwidth used: | 6-8 Mbit/s |
| CPU occupied: | 22-25% |
| Notes: | No slowdowns detected |
| Test #5 | |
| Hardware: | P4 2.0Ghz Notebook, 512 Mb ram |
| Op. System: | RedHat Linux FC 3.0 |
| Runtime: | Sun Server VM 1.4.06 |
| Test Settings: | 3500 clients in 70 rooms sending 40 characters long messages every 9 sec. |
| Bandwidth used: | 10-12 Mbit/s |
| CPU occupied: | 90-92% |
| Notes: | No slowdowns detected. We tweaked the heap size of the Virtual Machine to min=256Mb and max=256Mb. The test was run for 3 days. |
