WFilter Monitoring Performance
WFilter is designed to monitor a network with no more than 1000 computers, and the available internet bandwidth of the entire network shall be no more than 100Mbit/s.
Since WFilter is software, the performance depends a lot on the hardware performance. Higher bandwidth requires faster CPU, and more monitored computers require more RAM. Therefore, we recommend you to provide 1M available RAM for each monitored computer.
Below is a performance test result for HTTP request of WFilter 3.3 file-based version:
| # | Computers | Bandwidth | Total HTTP Requests | Recorded Percent | CPU | Memory |
|---|
| 1 | 50 | 37.2M | 16000 | 100% | 35% | 260,298K |
| 2 | 100 | 35M | 20000 | 100% | 38% | 280,576K |
| 3 | 200 | 31M | 40000 | 100% | 58% | 294,561K |
| 4 | 400 | 33M | 80000 | 100% | 68% | 372,786K |
| 5 | 600 | 32.3M | 120000 | 100% | 80% | 540,151K |
| 6 | 1000 | 32.6M | 200000 | 60% | 99% | 540,664K |
As we can see from the above table, when monitored computers number reachs 1000, the "recorded percent" decreased to 60% suddenly. And we noticed the memory only slightly increased, so it shall because lack of memory. Therefore we added the monitoring computer RAM to 2G, and do the test again:
| # | Computers | Bandwidth | Total HTTP Requests | Recorded Percent | CPU | Memory |
|---|
| 7 | 1000 | 32.7M | 200000 | 100% | 90% | 820,640K |
And the test of WFilter 3.3 database version(SQL Server) performance has the similar result:
| # | Computers | Bandwidth | Total HTTP Requests | Recorded Percent | CPU | Memory |
|---|
| 1 | 50 | 34.9M | 10000 | 100% | 45% | 197,392K |
| 2 | 100 | 34.9M | 20000 | 100% | 45% | 210,196K |
| 3 | 200 | 31M | 40000 | 100% | 45% | 270,960K |
| 4 | 400 | 32.9M | 80000 | 100% | 45% | 364,234K |
| 5 | 1000 | 28.6M | 200000 | 58.84% | 100% | 540,664K |
The performance of 1000-user can also be improved by adding RAM of the monitoring computer.
