Comment 24 for bug 1100843

The results of comment 23 suggest that the issue is not 100% reproducible. Can you please run the benchmark 3-4 times (presave/postrestore) and showall 4 results? One benchmark only, e.g. "simple read" will do.

Also please try putting a big file on disk (something like "dd if=/dev/zero of=bigfile count=64K bs=64K") and then doing "cat bigfile > /dev/null" after restoring. Please check if that makes performance more consistent.
