What kind of coin is this? How can a pool with more than 3mhs gets only orphans in more than 1 hour?
A pool has the same problems as a solo miner in this situation: Ultra-fast new blocks, barley time to catch up & hash.
Also longer delay for a pool: First, pool has to notice from elacoind that there is a new block, then pool needs to pass this notice onto the miners. By then, new blocks are already there.
I guess it cannot be avoided as long as blocks show up in <10s intervals.
All depends only on good connections to other nodes so YOUR block gets accepted and you know about new blocks first.
Hashing power only comes into play later on.
