Database in a simple ascii file

[Rafael Mentz Aquino]

Hi,

How many lines can I have in a simple ascii file before
I start to loose performance when I open this file and
put all the lines in a dict, turning the first column into the key
and the rest of the line into a list associated to that key.

(my file has just 100 lines, but that question starts to bother me ;-)

Thanks!
