Hello, I have good news in the test 2, however in test 3 ... @Christ, on Linux I got 0.00% erros. MHD is so fast on Linux that I believe that it can support C10K <https://www.nginx.com/resources/wiki/?highlight=c10k> problem. :-)
@Evg, do I need to change the `FD_SETSIZE` and the MHD source before compiling or in the `CMakeLists.txt` of my example? So, I did more tests after read Evg's messages. Now all results that I'll show uses keep-alive. Test 1: MHD_start_daemon( MHD_USE_THREAD_PER_CONNECTION | MHD_USE_DEBUG, PORT, NULL, NULL, &answer_to_connection, NULL, MHD_OPTION_END); 40~50% erros. And it returns a lot of `Server reached connection limit (closing inbound connection)` and some `Server reached coServer reached connection limit (closing inbound connection)`, OK, after read this log, I did: Test 2 (thanks Evgeny): MHD_start_daemon(MHD_USE_THREAD_PER_CONNECTION | MHD_USE_DEBUG, PORT, NULL, NULL, &answer_to_connection, NULL, * MHD_OPTION_CONNECTION_TIMEOUT, (unsigned int) 240,* * MHD_OPTION_CONNECTION_LIMIT, (unsigned int) 16000,* MHD_OPTION_END); *Samples: 15000.* *0,00% erros.* *95% line: 3.* *99% line: 5.* OMG, now MHD is so fast! :-o But, make this small change in your JMeter config: https://dl.dropboxusercontent.com/u/135304375/snip1.png (I can send a new jmx file if you prefer) and in the MHD example: * MHD_OPTION_CONNECTION_LIMIT, (unsigned int) 16000 * 2,* 1,84% erros. And a lot of: `Failed to create a thread: Not enough space`. OK, so I disabled the "thread per connection": MHD_start_daemon(*MHD_USE_SELECT_INTERNALLY *| MHD_USE_DEBUG, PORT, NULL, NULL, &answer_to_connection, NULL, MHD_OPTION_CONNECTION_TIMEOUT, (unsigned int) 240, * MHD_OPTION_CONNECTION_LIMIT, (unsigned int) 16000 * 2,* MHD_OPTION_END); *Samples: 27255.* *Error: 99,61%. LOL* And it locks the last requests. Sorry for my ignorance, but MHD_USE_SELECT_INTERNALLY should be the more fast MHD option, then or I did something wrong in my test, or this MHD option has a small bug on Windows. :-/ ps. I need to test the `FD_SETSIZE` option, so I'll wait for Evg's answer. :-) On Mon, Dec 7, 2015 at 4:53 AM, Christian Grothoff <[email protected]> wrote: > Hi! > > I tried your script on my system, with keep-alive, and I get 0.01% > errors (throughput: 5395.7/sec, 860.2 kb/s for 15000 samples). > > If I change the code to add the "close" header, I get 0.13% errors, > 3425/sec throughput, and 535kb/s, which I'd say is expected. > > So this seems to be (again) a W32-specific issue :-(. > > -Christian -- Silvio Clécio
