u...@dude.ptx:/ptx/src/git/linux.git$ sudo sh -c "echo 3 >
/proc/sys/vm/drop_caches"; time git --no-pager show v5.2
tag v5.2
...
real 0m13.225s
user 0m0.355s
sys 0m0.336s
So this doesn't seem to be the problem. Also the local configuration
can be ruled out:
u...@dude.ptx:/ptx/src/git/linux.git$ sudo sh -c "echo 3 >
/proc/sys/vm/drop_caches"; time env GIT_CONFIG_NOSYSTEM=1 HOME=/nonexistant
XDG_CONFIG_HOME=/nonexistant git --no-pager show --no-color v5.2
tag v5.2
...
real 0m13.587s
user 0m0.335s
sys 0m0.336s
Thanks
Uwe
