Hi
My config.
Processors 1 
Model Pentium III (Katmai) 
Chip MHz 596.93 
Physical Memory 754.85 MB
Memory Usage 
Type                    Percent Capacity  Free          Used          Size 
Physical Memory   98%                   16.73 MB   738.11 MB  754.85 MB 
Disk Swap               0%                  258.85 MB     0.00 KB   258.85 MB 
Is it normal that 650 - 700 MB is used as cached memory ?
Thanks.
