At least in my tests SCST performed significantly better than STGT.
These tests were performed with the currently available
implementations of SCST and STGT. Which performance improvements are
possible for these projects (e.g. zero-copying), and by how much is it
expected that these performance improvements will increase throughput
and will decrease latency ?
