Finally, when looking at the 7-Zip compression performance did Ubuntu Linux not secure a first place finish. Ubuntu 10.04.1 LTS was faster than Nexenta / OpenSolaris, but PC-BSD 8.1 was 4% faster than the Linux number.
PC-BSD 8.1 also overtook Ubuntu and the OpenSolaris operating systems when it came to compressing a 256MB file using LZMA on this AMD Opteron workstation.
Ubuntu's Lucid Lynx returned to producing a strong first place finish when it came to encrypting a 1GB file using GnuPG where it was 43% faster than the vanilla OpenSolaris b134. With GnuPG under Nexenta Core Platform 3.0, its performance was better than that of upstream OpenSolaris, and at the same speed as PC-BSD.
