Hi everybody, I have several questions about the speed of our ocserv, looking to some interpretation. As I monitored before, the ocserv can reach up to 300-500KB/s for each connection when the network got a little congested, though the speed could multiple several times nearly to 3MB/s even more perhaps when I visited the speedtest.net, nperf.com and etc.. These websites just utilize multiple connections via 8080 port. It's same(linear addition) when I just multi-requested a url download using chrome at one moment. No matter how I tested, the ping response to the VPN gateway never glitched(avg 50ms, StDev 5ms, loss rate 1%). The CPU load was only 5% at most, and still with about 100M remaining memory. In a word, I am not sure where the bottleneck lies. I saw some analysis about the bottleneck of virtual adapters, does it mean the ocserv also got a performance loss due to syscall? Or is there any tool I can use to detect? Regards, Yick
