[jira] Updated: (HTTPCLIENT-925) HttpClient 4.0.1 is approx. 3 time
slower then older 3.1 when works against www.google.com
[ https://issues.apache.org/jira/browse/HTTPCLIENT-925?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Oleksandr Alesinskyy updated HTTPCLIENT-925:
--------------------------------------------
Attachment: google.zip
As Sebb suggested, I tried both benchmarks against "local" Google, in my case google.de. Results for both versions are almost identical (4.0.1. is slightly slower but it is explainable as google generates longer responses for requests sent over 4.0.1).
But for google.com difference persists. That means that ways to "wrap" requests in 3.1 and 4.0.1 are not semantically identical and this fact better to be reflected in the documentation.
See results in the attached zip, filenames are self-explanatory.

> I have tried benchmarks from httpclient-benchmark - results are some what funny - while for most tried sites 4.0.1 is marginally faster then 3.1, for a couple of sites it is significantly slower, the most noticeable for www.google.com, test were repeated multiple times, here are sample output from 4.0.1 and 3..1
