Apex CPU time limit exceeded while updating through Data loader

Hii Nitish,

It seems like you are using nested for loop in your code which is making constant hit to the DB. Since Salesforce has certain limitations such as 100 SOQL queries limit 150 DML statements etc. and similarly it inserts or updates the record 200 at a time for bulk insertion or updation through data loader.

So I would suggest try to optimize your code or share your code.

Thanks.
