GOGC in gocql benchmark

[martin-sucha]

gocql readme recommends increasing GOGC. Should the benchmark use a higher value than the default?

For example with GOGC=100 (the default) I get:

Benchmark configuration: main.Config{nodeAddresses:[]string{"127.0.0.1:9042"}, workload:2, tasks:1000000, concurrency:1024, batchSize:256, dontPrepare:false}
Starting the benchmark
Finished
Benchmark time: 8927 ms

and with GOGC=500:

Benchmark configuration: main.Config{nodeAddresses:[]string{"127.0.0.1:9042"}, workload:2, tasks:1000000, concurrency:1024, batchSize:256, dontPrepare:false}
Starting the benchmark
Finished
Benchmark time: 7213 ms
