SP 2010 concurrent delete action

Hello,      

This is regarding SharePoint simultaneous deletion of a list item. Actually, we have a custom webpart which allows some authorized users to delete sharepoint list item. So, my question is that if no. of simultaneous user is between 4-100, will there be any issue with the operation in SP2010?? Is there any limitation in terms of simultaneous user actions on a particular list?

Please revert as i did not find anything on this.

Thank You
