We tested v3 RC13 and it has big problem when running 300+ PPPoE connections at the same time. CPU load is very higher than in 2.9.49, around 80%, when in 2.9.49 is about 50% on the same hardware.
Packet Loss through tcp/ip connections is non stop, measured with tool smokeping:
1.80% average and 9.08% high.. through 8 hours of test time to few IP addresses.
I suppose the problem is CPU load as when there is lower number of concurrent PPPoE connections than 150 there is no Packet Loss.
When running 500+ pppoe connections under V3 FINAL packet loss is lower than was in rc13...
