Hi,
I tried ramdisk again with more running process, and the script failed very
early just like Mr Dlion reported previously. It is about 20 minutes on
my machines.
1. The script use nvi-1.79 tar ball
2. Prepare 64MB ramdisk, and mkfs on it.
3. edit the first three lines and run the script below(its name is xc-1.2)
4. wait half an hour and see the result will be in /tmp/xcresult
Thanks,
Yoshi
