Hi Nicolas, > If you go higher and actually > intend to use all of this swap space, you will likely suffer serious > performance problems because the system will spend all of its time > swapping (a condition known as thrashing). " A system will traditionally use swap space when it runs out of memory for the task it's running. Think production environment with very heavy load like database dealing with a LOT of requests etc. A good tip taken from the RHEL 4 installation manual (http://www.redhat.com/docs/manuals/enterprise/RHEL-4-Manual/x8664-multi-install-guide/s1-diskpartitioning.html#S2-DISKPARTRECOMMEND) is "If your partitioning scheme requires a swap partition that is larger than 2 GB, you should create an additional swap partition. For example, if you need 4 GB of swap, you should create two 2 GB swap partitions. If you have 4 GB of RAM, you should create three 2 GB swap partitions." but bear in mind we're talking production server and not workstation. > > i can't understand why if create a really big swap partition i will have > a performance decrease????It seems to me > that in the worst case scenario, i will be throwing disk space [because > the system will never use the swap partition if it doesn't need > it......why this would have a negative impact on the system......] This is because you see it from the user point of view... A home user with recent hardware will usually not suffer or notice load on his/her machine. Go with the default from the installer. > thanks in advance, > > Nicolas Ang > Hope this helps Thierry -- (o< Thierry Sayegh de Bellis //\ RHCE V_/_ UK -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list
