When compressing a 2GB file using Gzip compression under a 32-bit environment the times were effectively the same. However, when it came to the 64-bit tests, Debian GNU/Linux was one second (or about 6%) faster than Debian GNU/kFreeBSD.
The LZMA compression results were similar to that of Gzip with the 32-bit numbers being close to the same, but 64-bit wise the Debian GNU/Linux with EXT3 was the frontrunner.
Next we turned to look at the encryption performance of Debian GNU/Linux and GNU/kFreeBSD. The 32-bit version of kFreeBSD was about the same speed as Linux, but when it came to 64-bit computing the Debian GNU/Linux was in front.
Continuing with the encryption theme we next turned to the Gcrypt library directly where we ran a test using the CAMELLIA256-ECB cipher. Both the 32-bit and 64-bit versions of Debian GNU/kFreeBSD slaughtered Debian GNU/Linux in terms of overall performance. Debian GNU/kFreeBSD was about 40% faster than Debian GNU/Linux when dealing with the Gcrypt library.
