> When running Arrow Flight benchmark in the following scenario, the output is
> incorrect.
> {code}
> $ ./arrow-flight-perf-server &
> [1] 12986
> Server host: localhost
> Server port: 31337
> $ ./arrow-flight-benchmark -server_host localhost -test_put
> Using remote server: true
> Testing method: DoPut
> Server host: localhost
> Server port: 31337
> Bytes read: 1280000000
> Nanos: 496372147
> Speed: 2459.25 MB/s
> {code}
> {{Using remote server}} should be {{false}} and {{Bytes read}} should be
> {{Bytes write}}.
> To correct the result of {{Using remote server}}, we can:
> * Change {{if (FLAGS_server_host == "")}} to another condition which checks
> if there is already an {{arrow-flight-perf-server}} running. This is a bit
> complicated to do and might add some unnecessary complexity (e.g. we need to
> make sure it support all OSes.).
> * Delete {{Using remote server}}, since we already have {{Server host}} in
> the output.
> I personally prefer the second option and will make a PR.
