| /** |
| * @file perf_get.c |
| * @brief benchmark simple GET operations (sequential access). |
| * Note that we run libcurl in the same process at the |
| * same time, so the execution time given is the combined |
| * time for both MHD and libcurl; it is quite possible |
| * that more time is spend with libcurl than with MHD, |
| * so the performance scores calculated with this code |
| * should NOT be used to compare with other HTTP servers |
| * (since MHD is actually better); only the relative |
| * scores between MHD versions are meaningful. |
| * Furthermore, this code ONLY tests MHD processing |
| * a single request at a time. This is again |
| * not universally meaningful (i.e. when comparing |
| * multithreaded vs. single-threaded or select/poll). |
