Importing accounts

I am in the process of importing a csv with accounts. There are about 40 columns counting the existing fields and additional fields that were added. The csv contains about 700 accounts.

It has taken several hours and still says processing. During this time the system is unresponsive to other requests or just really slow. The browser just spins and says connecting. It is using less than 5% of the cpu and about 1.3 out of 8 gigs of ram.

I am running 8315 32bit on Windows server 2012 and a SQL server.

How long should it take? Is there a way to know that it is actually still working?

**Update: 4 Hours have passed and it is still processing. I am able to get to it now from another web browser. The system does not show any additional accounts. Is that normal?
