How to set the no of mappers?

I am running a job with input file of 5000 records.but actually it is a
small file for hadoop..but i need to know whether it can be exceuted faster.

when i tried to run my job it took nearly 30 min to complete my job...
why so?

If i set my mappers to a lower count whether any reflection happens to my
job performance?
