Can anyone comment on the speed/performance of TrueCrypt, EncFS, and similar on older systems, e.g. a 5 - 7 year old laptop? I'm considering carrying a "sacrificial" machine in case it is, um, "indefinitely detained", but I'm uncertain what kind of a performance hit full disk (or partition -- though I'm inclined to encrypt the entire disk) encryption will incur. (I currently have Core Duo and P4 candidates for the job.)
- tjoff 15y agoTruecrypt has a simple benchmark that you can try (and I think it has a portable installation option so you don't even have to install it on the system to try it out). My core duo 1.6 GHz laptop gets about 60 MB/s of AES encryption/decryption speeds on battery (which I think reduces the clock to 1 GHz). I consider the impact negligible. However if you have an SSD in your system and do full-disk-encryption you will loose potential TRIM-support which can have a significant performance penalty depending on drive.
- pasbesoin 15y agoThank you for the response. These are both "spinning plates" machines. Part of what would keep their loss a minor financial hit. I wonder whether the dual cores help significantly. (As I'm more inclined to make the P4 the sacrifice.) However, if your observation is that the perceived impact is "negligible", this encourages me that it will be acceptable, if more significant, on the P4. I hadn't noticed the benchmark utility you describe. I'll have a look for/at it. Thanks!
