Hi Team Calculate

On Calculate MATE, on HDD with 2Go RAM CPU Quad Core 2GHz:

time emerge -pv vlc

real    1m29.395s
user    0m50.782s
sys     0m1.359s

For an update :

 time emerge -pvUDN --with-bdeps=y @world

real    0m37.917s
user    0m37.470s
sys     0m0.444s

On CLD, on HDD with 4Go RAM CPU Quad Core 2,3GHz:

time emerge -pv vlc

real    0m4.870s
user    0m4.755s
sys     0m0.112s

For an update :

 time emerge -pvUDN --with-bdeps=y @world

real    4m27.318s
user    3m50.672s
sys     0m4.617s

Is it possible to accelerate emerge?

Thanks !

In portage there is a problem with http binhost.

Try to use ftp binhost (write in /var/lib/calculate/calculate.env):

[update]
cl_update_binhost_list = ftp://mirror.yandex.ru/calculate

And re-scan cl-update --scan -s. After this try running the command twice:

time emerge -pv

Updated by Adrien Duck almost 3 years ago

With HTTP mirror (emerge -pv vlc)

real 0m11.205s
user 0m11.028s
sys 0m0.169s

With FTP mirror :
real 0m14.031s
user 0m11.134s
sys 0m0.178s

3 days ago, with http mirror, before These are the packages that would be merged, in order message, we waited 30 seconds. Not today.
