You're wrong on the performance front. That is a sparc |
| 2 |
myth, and only applies to sparc. It is true that executables |
| 3 |
will generally consume more memory, and therefore have longer |
| 4 |
startup times, so for small apps that get run very often but |
| 5 |
rarely do anything at all, it could theorhetically be slower. |
| 6 |
But the fact is the performance numbers as a whole far outweigh |
| 7 |
the statistically few apps that would be penalized. Things like |
| 8 |
JAVA, SQL DBs, Mozilla, KDE/Gnome, POVRay, compilations, are |
| 9 |
all considerably faster in 64bit mode from my experience. |
| 10 |
|
| 11 |
Also, with that same argument you made, why do we have a amd64 |
| 12 |
port ?? Why don't we have just the stanard x86 port, that compiles |
| 13 |
a 64bit kernel, and has a 32bit userland. Oh and yes, I am also |
| 14 |
the lead for amd64 ... |
| 15 |
|
| 16 |
Basically trust me on this one, unless you have a machine that can |
| 17 |
prove it. Like I said, sparc's are different beasts (too many poor |
| 18 |
design choices IMHO) |
