Not if you are putting swap and root on LVM.

2.6 kernels are capable of swapping to partition, file and logical volume with the same performance plus or minus a small overhead (microseconds), but the performance hit for a system in swap really negates any of that. Make sure if your system starts to hit swap you add more memory or tune your applications with a ceiling.
