Description Berthold Gunreben 2005-08-24 15:46:28 UTC 
as root, when doing a grep on a big file with several different tags, it 
happens that the grep is very slow. The reason is, that LC_CTYPE=en_US.UTF-8 
while all other language variables are POSIX. This means, that libc does lots 
of conversions between POSIX and en_US.UTF-8 what costs way more CPU time than 
the grep itself.
Comment 2 Berthold Gunreben 2005-08-31 09:28:14 UTC 
Is there some progress on this issue? I understand that this is a system 
inherent problem, but the performance impact is too big to just ignore.
Comment 3 Andreas Schwab 2007-03-26 15:15:08 UTC 
Should be fixed now.
