同意楼上,附Redhat Service关于swap的意见:
Considering that
1) At installation time when configuring the swap space there is no easy way to predetermine the memory a workload will require, and
2) The more RAM a system has the less swap space it typically needs, a better swap space requirements rule for Red Hat Enterprise Linux 5 is:
*Systems with 4GB of ram or less require a minimum of 2GB of swap space
*Systems with 4GB to 16GB of ram require a minimum of 4GB of swap space
*Systems with 16GB to 64GB of ram require a minimum of 8GB of swap space
*Systems with 64GB to 256GB of ram require a minimum of 16GB of swap space |
