Why is creating snapshots using elastio-snap much slower than using dattobd?

[sshipanoo]

While creating a snapshot for a 4TB LV volume, I noticed that using dattobd completes very quickly, but using elastio-snap is extremely, extremely slow.

I tried it on a 6TB volume and the snapshot command takes over 20 minutes to finish.

The symptom that it takes a long time to take a snapshot occurs in release 0.12.2, and it no longer occurs in the latest source code.
