Hi,

Hi, I use the find version 4.4.0 and have slow problems when use this comand
(it delays 10~15 minutes) in a directory with more than 530.000 files:

find /home/xxx/www -newer /home/xxx/flag

where flag file has the time of the last search.

How can improving ? Sometimes (1 in 10) it's show the results in seconds (why
sometimes), but in generally delays more than ten minutes.

I testing in two servers, one with two SATAII in RAID software mode and the
other one SATAII. Both are Debian 2.6.2x i386 and EXT3 and the times it's
similar in both.

Here four results running the find command with time:

real    6m11.324s
user    0m1.236s
sys     0m16.513s

real    12m56.431s
user    0m1.620s
sys     0m19.421s

real    13m38.488s
user    0m1.512s
sys     0m19.869s

real    13m27.678s
user    0m1.652s
sys     0m19.417s 

Thanks, Bernardo.
