I use 1GB as well. It would be helpful if you provide me with a script
that does these random timings between reads. Also, I noted that after
one read, no I/O is going any more on the target side, as this 1GB
probably gets cached. My backing store is an sdb block device and I
wasn't sure what's your and if you have caching at all, maybe this
influences something.
