Sender and receiver use the same operating systemThe aim of this testcase was to measure the throughput of an SCTP association where the saturated sender and the reveiver were on different machines. The machines are connected via a GBit Switch and an MTU of 1500 Bytes. We measured the throughput for different user message sizes ranging from 10 bytes to 1500 bytes. The sender always sent a million messages. The Nagle algorithm is used.
Sender and receiver use the same operating system
Different receiving operating systems
Different sending operating systems
All measurements show that the throughput decreases when the user messages have to be fragmented.
Please note that we were not able to provide results where Solaris is the sending end and Linux the receiving.
