Is it better to have one table with many entries
Example
----------
Email
Name
Address
City
....

or to have multiple tables with fewer entries
Example
----------
Table1

Email
Name

Table2

Address
City

Basicly, i'm looking at designing one table with about 25+ entries or spliting them up in to 3-4 categores and creating a table for each, and i'm looking for the better option, the option that will give me better performance. To me either one doesn't matter, but if one will performe better, obviously i'd like to use that one.
