Comment(by mazda):

 Here is the results for obfuscated test:

 on obfsproxy+tor:

 curl --socks5 127.0.0.1:5000 http://00.00.00.00/testfile.zip -o day2.zip

 weird! isn't it? I've never experienced this speed over tor before!
 but at the very same time, on my other machine (Mac OS X). I'm
 experiencing pain over tor! pretty slow!

 I'm gonna test it once again...

 on tor:

 curl --socks5 127.0.0.1:9050 http://00.00.00.00/testfile.zip -o day2-4.zip
   % Total    % Received % Xferd  Average Speed   Time    Time     Time

 more realistic this time

 so now I will delete my tor data to make sure everything is alright:

 rm -rf ~/.tor/*

 now will start obfsproxy and test again...

 on obfsproxy+tor:

 the result is... impressive!

 curl --socks5 127.0.0.1:5000 http://00.00.00.00/testfile.zip -o day2-5.zip
