It looks like Ozcoin is processing all transactions, Bitparking is passing along no transactions, and Deepbit has a transaction fee threshold that prunes lower fee and/or free transactions from their blocks.
The question then, is, does this make a difference to them? Are deepbit (and to a lesser extent bitparking) keeping a low orphan rate or is this barking up the wrong tree? I still get the feeling we're missing the underlying cause for this since it predates the abrupt rise in the number of transactions.
went and dug through the DB
We have had 12 orphans since we went DGM 30/12/2011
2 were our fault when we didnt get the BIP16 updates right
so 10 orphans for over 6.5 months
The last 2 were 15th and 8th of this month, whilst either or both of these may be attributed to current issues, we are not showing an unusually high orphan rate.
We spent quite some time over the last 24hours looking to see what we could do poolside to help the longpolls, stales and big block issues.
We came to the conclusion that apart from optimising some logging and databases some more to reduce load there isnt really much we can do, this is a network issue and the pools will need help from the devs to resolve.
Ozcoin will continue to accept all standard transactions into our blocks, we do not see any advantage to restricting the number of transactions in our blocks.
On a side note, value of txns included with blocks has gone from 0.0x to 0.x with a lot around 0.3 and we had one block with more than 1BTC in txn fees.
