There is nothing wrong with this. The only reason for 2x swap is so you could dump kernel image should you want to debug a crash. Otherwise, if you ask me, 4GB of swap is waste of disk space, but then again, nowadays harddrives are so large that it doesn't really matter. -Simon On Fri, 18 May 2007 08:46:15 +0800, Tzu-Hua Wang wrote: >Hi, >I have 4G RAM totally. >The SWAP is now 4G now. >Is it ok? >Thanks >2007/5/18, Tim Aslat <tim@spyderweb.com.au>: >> >> In the immortal words of Tzu-Hua Wang on 05/17/07 20:27: >> > Hi, >> > I added 2G RAM to my server.
