Volleyball: Slow HTTP Requests

If I make two HTTP requests to the same URL, one with HttpClient and the other with Volley, Volley requests take much longer.

For example, in my test environment:

  • using HttpClient to request google.com averages of around 250 ms
  • using Volley to query google.com averages about 750 ms

here is the Volley request sample log dump:

11:44:14.766: D/Volley(863): [1] MarkerLog.finish: (773 ms) [ ] http://google.com 0xa46e044c NORMAL 1 11:44:14.766: D/Volley(863): [1] MarkerLog.finish: (+0 ) [ 1] add-to-queue 11:44:14.786: D/Volley(863): [1] MarkerLog.finish: (+0 ) [93] cache-queue-take 11:44:14.786: D/Volley(863): [1] MarkerLog.finish: (+7 ) [93] cache-hit-expired 11:44:14.796: D/Volley(863): [1] MarkerLog.finish: (+1 ) [97] network-queue-take 11:44:14.806: D/Volley(863): [1] MarkerLog.finish: (+722 ) [97] network-http-complete 11:44:14.806: D/Volley(863): [1] MarkerLog.finish: (+20 ) [97] network-parse-complete 11:44:14.816: D/Volley(863): [1] MarkerLog.finish: (+16 ) [97] network-cache-written 11:44:14.826: D/Volley(863): [1] MarkerLog.finish: (+0 ) [97] post-response 11:44:14.836: D/Volley(863): [1] MarkerLog.finish: (+7 ) [ 1] done

as you can see, the bottleneck is in the actual http request. Why is it so slow?

Volleyball seems to be caching your answer. Using HttpClient does not cache anything directly.
