I used ab(apache bench) to test with handle 1000 requests, with a maximum of
300 requests running concurrently (ab -n 1000 -c 300), and then I received
the output as follows:

Concurrency Level:      300
Time taken for tests:   6.797 seconds
Complete requests:      1000
Failed requests:        0
Write errors:           0
Non-2xx responses:      1000
Total transferred:      162000 bytes
HTML transferred:       0 bytes
Requests per second:    147.13 [#/sec] (mean)
Time per request:       2039.063 [ms] (mean)
Time per request:       6.797 [ms] (mean, across all concurrent requests)
Transfer rate:          23.28 [Kbytes/sec] received

Connection Times (ms)
              min  mean[+/-sd] median   max
Connect:        0    1   4.7      0      78
Processing:   234  979 310.6   1016    4141
Waiting:      219  632 230.1    609    4141
Total:        234  980 310.7   1016    4141

Percentage of the requests served within a certain time (ms)
  50%   1016
  66%   1141
  75%   1203
  80%   1219
  90%   1313
  95%   1453
  98%   1469
  99%   1484
 100%   4141 (longest request)


I wonder that 147 requests per second is too low?
