Unless what you are doing is heavily I/O dependant (mostly heavy database workloads), that's not really true anymore, especially with a modern CPU and say, LUKS encryption. Phoronix has a recent review of FDE using LUKS, and apart from synthetic I/O tests, the difference isn't really observable.

Try cryptsetup benchmark on your pc and look at the results for aes-xts for example.
