InnoDB, 1 file per table or 1 BIG table?

[Ow Mun Heng]

Hi All,

Just wanted to know if it would be faster/better to implement this
option into my.cnf

innodb_file_per_table = 1 

which would essentially make each table a file on it's own rather than
have it all in 1 file.
My belief is that it would be slightly more advantageous compared to 1
BIG file.

eg: 1 10GB file would perform poorer than 10 1GB files. 

Is this statement true and how far is is true?
