Go up one level in this thread


Roy,

I get a Shredder Mark of 861 with 192 MB of Hashtables on a 1500 Mhz AMD with
512 MB of RAM.  The Pentium IV 2.8 GHz is obviously twice as efficient at
running code as the "old" AMDs. I suppose the ShredderMark is not a linear
measure. Then again.....

Don't worry be happy,


Tio Timmy
