I have started to use truecrypt in earnest over the past few weeks, but I have noticed that it *appears* to eat massive amounts of CPU cycles. I have it currently setup on 2 different hard drives - 1 80Gig deskstar (7.2k 8mb cache I believe), and 1 160Gig (same) running on a p4 2.8 with 1gig of DDR. On both these drives I am running apps that have moderate volume access. My cpu usage runs continually at nearly 100% bringing things to a crawl too often. Blowfish benched the fastest, by a wide margin, on my system so I use that on both drives. I guess my question is this - is that "normal" to see that level of performance hit on my setup? If "yes" what reasonable PC setup ought I to be looking for? A 3500+ a64 or dual core? Or is this a situation where I do not have enough RAM to do what I am doing? Thanks in advance for any tips.
