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. 2007/5/18, Simon : > > > There is nothing wrong with this.
