Lots of INSERT in oracle 10g

Question

Hello,
I have a table with 10 columns, with PK on first column.
I have a script with 3000 lines only INSERTs e.g. :
Line1: INSERT INTO table VALUES(...);
Line2: INSERT INTO table VALUES(...);
Line n: ...
Line 3000: INSERT INTO table VALUES(...);
I get this problem now: First 200th-300th INSERTs are made very quickly, but from 300th to the end (3000'th insert) it become more slower.
How do i solve this problem in order that every INSERT line will take the same time ?
Thank you.
