Sorry Rich, It does - as in; look like a network issue. But I fail to see how. If I try to push 10MB/s into openssl and everything works as expected until the available network bandwidth drops below 150 kpbs, this points at openssl - I think. That is right from 100Mbps down to 150 kpbs everything works as expected. As I continue tuning down the bandwidth below 150kbps openssl starts to stop sending data. It becomes very bursty and there are whole periods of seconds where no data is sent from openssl even though it's 17KB TLS buffer is full and pings, for example, can be sent and received normally. There appears to be some relation to the size of this buffer and the minimum achievable throughput we can get.. Unless my maths is off; 140 Kbps would give about 17KB/s throughput.. Coincidence? Have you tested sending large amounts of data between two s_clients across a limited bandwidth link? On 15 May 2015 12:20, "Salz, Rich" <rsalz at akamai.com> wrote: > ?It does?
