To give you an idea what we gain here, I compiled some numbers. GNU |
8 |
Emacs live ebuild (app-editors/emacs-cvs) will be the biggest consumer |
9 |
once they switch from CVS. |
10 |
|
11 |
First we will compare timings |
12 |
|
13 |
$ time bzr checkout --lightweight |
14 |
real 7m37.044s |
15 |
user 1m2.789s |
16 |
sys 0m2.807s |
17 |
|
18 |
$ time bzr checkout |
19 |
|
20 |
real 40m47.371s |
21 |
user 3m57.881s |
22 |
sys 0m8.586s |
23 |
|
24 |
So the normal initial checkout will be more than five times slower than |
25 |
the lightweight one. If this were 1s to 6s it would be neglectable, |
26 |
but we are talking about half an hour difference just for an emerge. |
27 |
|
28 |
Next ist the update function. |
29 |
|
30 |
$ time bzr update |
31 |
|
32 |
real 0m11.457s |
33 |
user 0m0.544s |
34 |
sys 0m0.092s |
35 |
|
36 |
$ time bzr update |
37 |
|
38 |
real 0m2.710s |
39 |
user 0m0.237s |
40 |
sys 0m0.053s |
41 |
|
42 |
Clearly the normal checkout wins by factor five, but we are in the |
43 |
second range, while the space gain is enormous: |
44 |
|
45 |
$ du -sch Emacs-lw/ Emacs |
46 |
106M Emacs-lw/ |
47 |
427M Emacs |
48 |
533M total |
49 |
