Thanks to David Frey, David Bronaugh and  Lionel Widdifield for their 
discussion. Now David (Bronaugh) I am actually searching for a general 
purpose file system which is fastest . I have a reiserfs file system  
as /dev/hda2 where my home, root etc are located. I also have a XFS partition 
as /dev/hda3 which I use as storage. You have suggested XFS as a best 
general-purpose filesystem. Could you kindly explain why you think it as 
best ? Regarding speed ? definitely I am interested in speed as power failure 
is not a problem as I have UPS which can alive the machine AT-LEAST 20 
minutes. 

EXT-2 file system is no doubt faster as it provides better result than EXT-3 
with my old P-I machine. But as the time progresses I am searching for some 
thing more matured file system. ( for my new AMD PC, not for that old P-I :-) 
definitely )
