Do 'ssltest' timings make sense (they are automatically displayed
while running 'make test')? In 'ssltest' and 'ectest', I always
use clock() and CLOCKS_PER_SEC, which are part of the C standard.
This is sufficient as long as you just want user time.
If you want elapsed real time ('openssl speed -elapsed'), you need
times(), which measures in clock ticks and not in CLOCKS_PER_SEC.
It seems the preferred way to get the correct number of clock ticks
per second is to use sysconf(_SC_CLK_TCK) and not the CLK_TCK macro.
So maybe changing the HZ definition in apps/speed.c as follows
might help:
#include OPENSSL_UNISTD
#ifndef HZ
# ifdef _SC_CLK_TCK
# define HZ (sysconf(_SC_CLK_TCK))
# else
/* ... */
#endif
