Dear Ccache community,
I have an amd64 kaveri box with 8GB RAM and run Gentoo stable on it.
I have just installed ccache with 2GB memory allocated to it.
I have tried some repeat compilations to see if there would be any speed
So far I have not seen much change but I am not skilled enough to improve
I tried compiling gcc, glibc and imagemagick but did not see much
My cache data looks like this:
djt /home/mikef # CCACHE_DIR="/var/tmp/ccache" ccache -s
cache directory /var/tmp/ccache
primary config /var/tmp/ccache/ccache.conf
secondary config (readonly) /etc/ccache.conf
cache hit (direct) 12997
cache hit (preprocessed) 517
cache miss 16291
called for link 2141
called for preprocessing 1709
multiple source files 4
compile failed 197
preprocessor error 62
bad compiler arguments 79
unsupported source language 2275
autoconf compile/link 1399
unsupported compiler option 8
no input file 2617
files in cache 44633
cache size 891.9 MB
max cache size 2.0 GB
Could you recommend a gentoo package that I could recompile twice that you
think is one that is ideally suited to benefit from ccache being installed?
