As Victor told you in another post that you submit

Actually ext3 filesystem is quite complex and mounting it takes some time.

It may take some significant time even on PC:

root@tecno:~# time mount /dev/sdb1 /mnt/sd

real    0m0.402s

user    0m0.008s

sys     0m0.016s

root@tecno:~#

Here /dev/sdb1 is quite small and fast SD card (4GB class 10 one).

If mounting time is very critical for you you can use other filesystem instead.

However it may cause some compatibility issues.
