I'll give it a spin. I am running on a quad-core Xeon system: Intel(R) Xeon(R) CPU E3-1220 V2 @ 3.10GHz, with 8GB of RAM, and the tests on a 3TB SATA III drive. My loop image files are like this: -rw-r--r--. 1 root root 268435456 Mar 12 09:53 img0 -rw-r--r--. 1 root root 268435456 Mar 12 09:53 img1 -rw-r--r--. 1 root root 268435456 Mar 12 09:53 img2 -rw-r--r--. 1 root root 268435456 Mar 12 09:26 img3 I've tried storing them both on ext4 and xfs, didn't seem to make a difference for the test results.
