If your main system is substantially faster at building, yes, I'd |
| 9 |
consider building everything on it and not bothering with distcc. |
| 10 |
|
| 11 |
BTW, you've not mentioned (nor asked about, but since it might speed |
| 12 |
things up for you...) what sort of emerge environment you use on either |
| 13 |
of your systems. |
| 14 |
|
| 15 |
If you've a decent amount of memory, with 4 gig it'll be very noticeable, |
| 16 |
in theory it could be down to a gig as well, but I honestly don't know |
| 17 |
what the results under 2 gig would be and whether it might have more |
| 18 |
negative effects than positive... |
| 19 |
|
| 20 |
Consider pointing PORTAGE_TMPDIR at a tmpfs. |
| 21 |
|
| 22 |
The idea is based on the fact that everything portage does in its tmpdir |
| 23 |
(/var/tmp by default) is temporary, erased as soon as it's done emerging |
| 24 |
that package. Since tmpfs uses swap backed memory, worst-case, it has to |
| 25 |
write to swap -- that is, to disk, which is where it would otherwise be |
| 26 |
writing ALL the temporary files. With memory access so much faster than |
| 27 |
disk access, every file that's erased before it hits disk saves time, and |
| 28 |
it can make a BIG difference in emerge times. |
| 29 |
|
| 30 |
So if you're not already doing it on your main machine and it has the |
| 31 |
memory, try it. And on the slower machine, with memory as cheap as it |
| 32 |
is, if it's possible to upgrade memory, consider doing so. You may then |
| 33 |
just find that emerges are fast enough that for packages not already on |
| 34 |
the main machine anyway, it's fast enough to merge them locally that it's |
| 35 |
not worth the hassle of doing the pkgonly thing on the main machine. |
