Re: [libmicrohttpd] 回复: Help : Any HTTP Performance Benchmark Comparison for Microhttpd with Go HTTP Servers

Hi Forrest,

I'm working on simple program that should demonstrate MHD performance.
It expects that performance is measured on the client side.

I'm not sure what's is not optimal with your current tests, however 
right now you can use '--enable-heavy-tests' configure parameter, which 
should enable building of src/testcurl/perf_get_concurrent11.
On my test machine with 16 cores (running on Debian SID) I've got the 
following:

Parallel GETs using internal thread with select(): 48307.692308 requests/s
Parallel GETs using internal thread with select() and thread per 
connection: 125600.000000 requests/s
Parallel GETs using internal thread pool with select(): 132210.526316 
requests/s
Parallel GETs using external select: 42576.271186 requests/s
Parallel GETs using internal thread with 'auto': 52333.333333 requests/s
Parallel GETs using internal thread with 'auto' and thread per 
connection: 179428.571429 requests/s
Parallel GETs using internal thread pool with 'auto': 119619.047619 
requests/s
Parallel GETs using internal thread with poll(): 52333.333333 requests/s
Parallel GETs using internal thread with poll() and thread per 
connection: 167466.666667 requests/s
Parallel GETs using internal thread pool with poll(): 147764.705882 
requests/s
Parallel GETs using internal thread with epoll: 52333.333333 requests/s
Parallel GETs using internal thread poll with epoll: 125600.000000 
requests/s
PASS perf_get_concurrent11 (exit status: 0)

configured with CC=gcc-13 CFLAGS=-O3 --enable-build-type=release

It is very surprising that the most efficient modes are 
"thread-per-connection" with 125-179k requests per second.

Actually this tools was not created to squeeze the maximum performance 
and it uses libcurl which is fast, but not optimised for maximim 
performance as will.

The new tool should be ready in a few days.
