When you don't use the software don't complain that it is buggy, because you won't find the bugs. You cannot always tell the others to make everything perfect. I don't want to have everything compiled on $COMPILER. I want that there is a reasonable quality. And for me quality is not only stability, but also speed. > Many suggested that the Linux binaries be run via the FreeBSD Linux=20 > emulation.

I (any many people) want efficient servers and eventually desktops. You should not expect people to tune the system for speed, when it's clear that default setting does not make any sense. People will use default settings, because they trust developers that they thought about balanced stability, security and performance. > FreeBSD has safe default. This is what I am talking about.

But if you don't tweak, you get a fair result in a benchmark. This is what you will see as a user of the system. These are the default settings, that means developers chose them as the BEST choice for the system. =20 > If your installation is pre-optimized, chances are it will crash all > the time on you and there will be no easy way for you to fix, short > of installing another "distribution". Sorry, no. If optimization makes bugs appear, there are bugs in the code (somewhere). And you will never find them when you hide them like this. You will also never see many advances in performance. -- Martin --Sig_/3wOr79UdKqdOz/Px5Xh3l2d Content-Type: application/pgp-signature; name=signature.asc Content-Disposition: attachment; filename=signature.asc -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.18 (FreeBSD) iQIcBAEBAgAGBQJO9JSMAAoJEF8wvLx/5p/7B70QAKjhEOblVtgDInsp7eHvvHWH FxrbRUjA+5XZywGs7qAbys2uEljX0CQ0Oe3s/pk56f0euyTyhQextYUnb9AiupG8 dPMz2e86oDhgeeIKJy2fNSZ3mh//7W1+JWU6VlaloExKNBIz/wXcMHiCI1gXtE0y opMGWIKHxyvcbrvWRI9fOyM6q7KZP1ygsbC/T3L7+jzr4SXOXVWHcOz35yh+tyBs XbUtZhu1EmkTNzpJOCmUfBm/bqY1RevNmMCOzBDsafB/opnJ9zqx5vagTmpxktfp G1e0V0pXoV22e3XDSAo0mMxR1pHqwegexdbUk2LZ9OnE/yz7NZhmjpSdjeoaE2fV 4o4LjAEaExkj2m96+neDDcbOh//2QJC76ijCIC0rA3Smjz+HPTlE0/o115S2mlCR MK0J6xWbTfQPl85kv9kZzJeGLQodjr6ttRgjXOQYLK1Lb2IZoqGAwrjv2qZj9r9h awosYg2tsMgsRQXNFV6/3oLpgPSamHCFoC4jlIA/7mLeemDS+EVcqUNf9h9JA9ey IgAG22RumA6XCPHyQ0TY+VtlJIJX0mdGk/5NWncPQKNHDr9ciWCogLFMPdIr8FE8 EPqTV6kk06FORReI6xNV/UVOZnKa2JfOazBiBdXPJwyJKgdN8eCAqNkZHAZC4Dd8 OoUoTI2t6q3+hYzc58rV =35Is -----END PGP SIGNATURE----- --Sig_/3wOr79UdKqdOz/Px5Xh3l2d--
