+/**
+ * @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).
