I have not really searched for such benchmarks for a while. I would |
| 19 |
take any such things with a grain of salt, if I did. Unless I want to |
| 20 |
devote the time to set up a series of application specific tests, and |
| 21 |
test them on multiple platforms on MY hardware, such results would be |
| 22 |
almost useless to me. I am sure that there are such tests out there - |
| 23 |
Computer Science and Engineering departments at Universities have |
| 24 |
certainly run such tests - whether they are public or not, is another |
| 25 |
story. |
| 26 |

Also, if you could specifically define "efficient", it would be |
| 28 |
helpful, at least to narrow down what you're looking for. If you mean, |
| 29 |
accomplishing the same task with the fewest instructions, that is |
| 30 |
difficult to test, and very dependent on Kernel, library and compiler |
| 31 |
versions. If you mean faster, that is more hardware dependent, unless |
| 32 |
you're dealing with some very poorly written code. |
| 33 |
|
| 34 |
Efficient does not always mean faster - as others have pointed out, |
| 35 |
binary distos are faster to install than source based distros. FreeBSD |
| 36 |
is faster than GNU/Linux on some tasks, and overall is more UNIX-like, |
| 37 |
since it was a Berkeley developed version of UNIX. This has been |
| 38 |
tested on other people's hardware. Would that necessarily compare to |
| 39 |
mine or yours? We don't know that, since we have NOT tested them on |
| 40 |
each of our sets of hardware. |
| 41 |
|
| 42 |
E.g. FreeBSD uses an older version of just about everything, so I |
| 43 |
cannot optimize the compiler for my Core-i7-avx processor. I can do |
| 44 |
this with Gentoo (or any other GNU/Linux distro that I choose to |
| 45 |
'optimize' by compiling from source). |

Just my $0.02, |
