I really "feel" no difference of performance or lags/delays butIn case that someone else is wondering abut performance like me and dosen't have time to bech,
With this occasion I did a
benchmark to see the difference.
But please keep in mind that when the system was NOT ecrypted It was on /dev/sda2 that is in the front of the hardisk, and the encrypted system is in /dev/sda6 and that is somewhere in the middle of the hardisk. If that matters a liitle.
