| ====== Load Test Result ====== | |
| **Server:** Bare metal server AMD EPYC 7713P 64-Core Processor. | |
| |
| **Parameters:** | |
| * number of packets (pkts), | |
| * number of bytes, | |
| * number of dropped packets (pkts dropped). | |
| |
| **Load:** Synthetic, from DPI. Steady at 99,999.55 Mbit/sec and 41,586,771.00 pkt/sec for 4 hours. | |
| |
| **Test Process:** Only 25 cores were used (39 cores in reserve). The service divided all traffic into 4 streams of 25 Gbps each, balanced by subscriber IP address. | |
| |
| **Result:** | |
| * no packet loss, | |
| * no drops, | |
| * no queue overflow. | |
| |
| **Conclusion:** The load balancer maintains a stable 100 Gbps load without losses over an extended period. On this equipment, a multiple increase in traffic volumes is possible. | |
| |
| **Description of core types:**\\ | |
| ''sys'' — system core\\ | |
| ''rx-dispatch'' — incoming data processing\\ | |
| ''slave'' — worker cores\\ | |
| ''ajb'' — adjacent job buffer, processing of adjacent tasks or data buffering\\ | |
| ''service'' — service core | |
