Hi Willy and William,
I ran some tests with the cache filter.
In http_action_store_cache(), the code indicates that only HTTP/1.1 is
cached. This explains why I failed on my first tests with apachebench :)
The protocol version is checked on the request side. Can't we rely on
the response side instead ?
Btw, here are some first results for those who are interested :
* WITHOUT cache
- ab -n100000 -c100 http://localhost/image.gif
Time taken for tests: 59.127 seconds
Requests per second: 1691.27 [#/sec] (mean)
Time per request: 59.127 [ms] (mean)
Time per request: 0.591 [ms] (mean, across all concurrent requests)
Transfer rate: 1344.43 [Kbytes/sec] received
- h2load -n100000 -c100 https://localhost/image.gif
finished in 60.06s, 1664.91 req/s, 1.11MB/s
* WITH cache :
- ab -n100000 -c100 http://localhost/image.gif
Same results as before, but once patched to rely on the response, we get
more interesting results :
Time taken for tests: 1.801 seconds
Requests per second: 55539.79 [#/sec] (mean)
Time per request: 1.801 [ms] (mean)
Time per request: 0.018 [ms] (mean, across all concurrent requests)
Transfer rate: 44149.79 [Kbytes/sec] received
- h2load -n100000 -c100 https://localhost/image.gif
finished in 1.49s, 67210.04 req/s, 44.80MB/s
for some details :
- image.gif = 510 bytes
- haproxy runs locally (the backend is in the same network) with this
configuration :
