About the SWAP

[Tzu-Hua Wang]

Hi Simon,
Thank you for your response.
Actually, when I setuped the FreeBSD 6.2R and used the default slice
configuration for my hard disk, FreeBSD
suggested that the SWAP should be 4G (with 4G RAM). I had had the same
suggestion when I had 2 G RAM before.

Thank you for your response again.
