Nobody commented my results, but I'm still curious :
----------------------------------- compiled "stress"
stress    : Total I/O =  425.6 Mbytes, I =  296.4, O = 129.3
stress    : Compr I/O =  407.4 Mbytes, I =  286.3, O = 121.0
stress    : Real Time =  98.70 seconds Cpu Time =  83.92 seconds
*  ROOTMARKS = 160.4   *  Root 2.21/07  990308/1327
----------------------------------- interpreted "stress"
stress    : Total I/O =  425.6 Mbytes, I =  296.4, O = 129.3
stress    : Compr I/O =  407.4 Mbytes, I =  286.3, O = 121.0
stress    : Real Time = 185.76 seconds Cpu Time = 167.58 seconds
*  ROOTMARKS = 152.3   *  Root 2.21/07  990308/1327
-----------------------------------
Note : both the Real Time and the Cpu Time of the interpreted "stress" are
about twice of the compiled "stress". But ROOTMARKS are the same ?
What's going on ?
Do you also observe this ( Rene, which result did you give in your
benchmark - compiled or interpreted ? Could you, please provide me with
BOTH results from your PII/400 ? ) ?
Is there somewhere a "table" which compares different machines ( I mean
something like it was done for root 0.8 ) ?
Thanks in advance,
Jacek.
