Reference time, on a X200 with a P8700, building from RAM on Tails takes at commit edf97d3:

real    48m53.368s
user    48m4.740s
sys 0m15.344s

On intri’s laptop:

Conclusions

no IA, no Farsi = about 5.5 minutes, and then IA alone adds 7 minutes, Farsi alone adds 5 minutes, and adding both together adds 12 minutes => almost 17.5 minutes

From the same commit after doing rm -r install upgrade I get:

real    30m22.595s
user    29m6.884s
sys 0m11.628s

which is 39% less and matches more or less what intrigeri gets.

Let’s try to reduce the build time by 1/3 then.

#5 Updated by sajolida 2016-02-21 21:21:24

After merging Bug #11135 and Bug #9671 I get:

real    43m19.589s
user    41m47.072s
sys 0m15.312s

which is 11% less already.

#6 Updated by sajolida 2016-02-22 17:45:41

Remove the old installation instructions (/install and /upgrade) also speeds about 4%.

#8 Updated by intrigeri 2016-02-22 20:35:23

At commit:9244ee23feb893aa1bf956b825bf0d0aa225e145 (after merging the branches for Bug #11135, Bug #9671 and Feature #11156) I see:

779.86s user 4.99s system 101% cpu 12:56.60 total

i.e. –25% :)

On my laptop (Intel i7-3520M CPU with the core used by ikiwiki running at 3.2 GHz, and a pretty fast SSD):

current

real    20m23.051s
user    20m39.604s
sys     0m7.780s

old school (no Farsi, no IA)

real    6m18.782s
user    6m20.312s
sys     0m3.664s

current minus Farsi

real    13m2.951s
user    13m19.244s
sys     0m5.444s

current minus IA

real    10m6.676s
user    10m8.244s
sys     0m4.436s

So very comparable figures to what you’ve all seen.

So, in my case the new target (- 1/3) would sill be 20m23s * 2/3 ~= 14m which is still pretty long. :/

In my Thinkpad the current website takes

real    9m18.094s
user    8m58.084s
sys 0m9.280s

I have 7.6 GiB memory, and an Intel® Core™ i5 CPU M 520 @ 2.40GHz × 4 processor

On an X201 with an i3 M350:

real   10m55.939s

#16 Updated by sajolida 2016-05-13 08:17:59

Today I’ve got 36m20.637s on my machine. That’s 26% less than my reference time.
