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
