I need some help with analyzing a log from Apache Bench:

Benchmarking texteli.com (be patient)

Completed 200 requests
Completed 300 requests
Completed 400 requests
Completed 500 requests

Completed 900 requests
Completed 1000 requests
Finished 1000 requests


Server Software:
Server Hostname:        texteli.com

              min  mean[+/-sd] median   max

Total:        115 6310 1675.8   6940    9022

Percentage of the requests served within a certain time (ms)
  50%   6940
  66%   6968
  75%   6988
  80%   7007
  90%   7025
  95%   7078
  98%   8410
  99%   8876
 100%   9022 (longest request)

What this results can tell me? Isn't 27 rps too slow?
