ну так-то фен с 3 ядрами и видимо 6 потоками(?), это очень даже ничего.
Linux® users are often surprised to find that Bash is not the default shell in FreeBSD. In fact, Bash is not included in the default installation. Instead, FreeBSD uses tcsh(1) as the default root shell, and the Bourne shell-compatible sh(1) as the default user shell. sh(1) is very similar to Bash but with a much smaller feature-set. Generally shell scripts written for sh(1) will run in Bash, but the reverse is not always true.
