Description
The new os2_randget() function in os2ea.c slows down login (and possibly other operations) considerably.
For each login the randbyte_hrtimer() subroutine is executed exactly 129 times, a DosSleep(5) occurs for every execution, this sums up to a delay of almost 0,7 secs per login.
My suggestion as a fix would be to remove the randbyte_hrtimer() portion completely (reducing DosSleep(5) to DosSleep(1) is better, but still slow) as randbyte_hrtimer() is only one of 3 components and the remaining randbyte_sysinfo() and randbyte_perf() still provide more "randomness" than what was available before Changeset #160 and the resulting login speed is perfectly acceptable this way.
An appropriate unified dif is attached.
