ccache

<< < (2/2)

Jason W:
Thanks, it is done.  For those not familiar with ccache here is a comparison between a fresh compile, or second compile without ccache, and a recompile with ccache:

First run - time ./configure --prefix=/usr/local && time make:


--- Code: ---(this is time ./configure --prefix=/usr/local first time)
CMake has bootstrapped.  Now run make.

real    16m5.336s
user    11m48.634s
sys     0m54.403s
root@box:/mnt/hda2/cmake/cmake-2.6.4#

(this is amke first time)
[100%] Built target documentation

real    26m33.680s
user    20m56.428s
sys     1m11.649s
root@box:/mnt/hda2/cmake/cmake-2.6.4#     


--- End code ---

Recompiling with same options using ccache:


--- Code: ---(./configure --prefix=/usr/local)
CMake has bootstrapped.  Now run make.

real    2m16.557s
user    1m36.454s
sys     0m25.858s

(make)
[100%] Built target documentation

real    2m28.569s
user    1m45.390s
sys     0m21.255s
root@box:/mnt/hda2/cmake/cmake-2.6.4#


--- End code ---

The reason I mention this comparison is that ccache is a way to make better use of older pentium 2 and 3 for compiling, as we know tweaking and recompiling is a common procedure with extension builds and this extension can save a lot of time.
