This is not what you would call every 10 - 15 minutes. Nothing special here, just some pool probably. I don't want to waste time investigating who the owner of this address is.
Update:
You already investigated it ages ago and found out it's the address from BTCChina Pool. It's been nine months since you wrote about it.
Apparently I did. Time is limited compared to back then.
