I prevailed on some friends to try out a non Redhat distro plus HPUX 10.20 :
1 United Linux 1.0 (x86 Linux 2.4.19 )
Value (i = index) BSD GLIBC (seconds)
random() * mod 0.35 0.56
i % mod 0.14 0.41
i / (ITEMS / mod) 0.10 0.27
i ^ 0x5555555 0.26 0.42
2 HPUX 10.20 (pa-risc1.1 D380 )
Value (i = index) BSD HPUX (seconds)
random() * mod 8.3 14.0
i % mod 2.9 4.9
i / (ITEMS / mod) 2.4 2.9
i ^ 0x5555555 7.8 13.8
The HPUX results are interesting !
