Large qcow2 performance

Hello,

I am considering creating a VM with a large qcow2, around 6TB in size. This 
Linux VM will be reading and writing a lot of small files to this very large
qcow2 using the VirtIO driver. Are there any concerns or guidance about creating
such a large qcow2, or performance issues with small files on a 6TB qcow2?

Thanks,

Andrew
