- Close sockets to ensure timely shutdown. This is the major improvement. Without this benchmarks would regularly time out - Switch to a logger with no output to make the benchmark output readable - Fix one unix socket benchmark to use unix socket opening function - Fixed BenchmarkGUID to be a valid test - and added a similar TestGUID With these changes I've also found I need to restrict b.N or NSQD takes too long to exit when N gets large. I've seen this in tests that publish only and do not receive messages. A large number of messages then need to be persisted and this takes tens of seconds. Once these changes are made `go test -bench . -run ^$ -benchtime 1000x` completes cleanly for me.
This is a dropin replacement for the standard library flate compression.

To really get the benefits of improving compression for go-nsq users we also need the same change in go-nsq. I've got a draft pull request here: nsqio/go-nsq#363
Similarly snappy performance needs nsqio/go-nsq#362
