Performance evaluation (AMD A8 7410 CPU)
Tag: record_cpu
Each payload was sent 2000 times.
| Payload size | Data Rate | CPU % | Total transferred |
|---|---|---|---|
| 2 kB | 5.49 MB/s | 84.4% | 3 MB |
| 4 kB | 7.72 MB/s | 81.6% | 7 MB |
| 8 kB | 8.22 MB/s | 78.2% | 15 MB |
| 16 kB | 9.23 MB/s | 79.7% | 31 MB |
| 32 kB | 9.32 MB/s | 77.3% | 62.5 MB |
| 64 kB | 9.10 MB/s | 76.3% | 125 MB |
| 128 kB | 3.30 MB/s | 43.9% | 250 MB |
| 150 kB | 1.10 MB/s | 20.1% | 292 MB |
- Peak data rates of 9.32 MB/s was recorded for 32 kB fixed payloads. (32 kB * 2000)
- Peak data rate exceeds the throughput measured in a study (for 10ms RTT)
- All of the above was recorded with retransmission wait times modified to (15 + n) milliseconds (n >= 0) which was found to be the optimal value.
