Public bug reported:
Forwarded from bug #605048.
Running "sudo update-software-center" causes an excessive amount of re-
stat()ing for a single translation-related file: it is stat()ing for
'app-install-data.mo' a quarter of a million times during the two-minute
run:
$ time sudo strace update-software-center 2>&1 | grep -c
'^stat64.*app-install-data.mo'
271169
real 2m1.576s
user 1m9.032s
sys 0m49.031s
It is likely that this is indicative of an inefficiency somewhere in the
process and that a good deal of the reported 'sys' time is probably
spend handling those calls.
** Affects: software-center (Ubuntu)
Importance: Undecided
Status: New
