According to BlockChain.info we seem to have lots of small blocks of
0-50KB and some larger 200-300 KB blocks. So in terms of near term
measure one thing I would like to know is why miners (i.e. no miners at
all) are fully exhausting the available block size despite thousands of
transactions in the memory pool. I'm not too familiar with the default
inclusion rules, so that would certainly be interesting to understand.
There are probably some low hanging fruit here.
The fact that SatoshiDice is able to afford to pay 0.0005 BTC fees and
fill up the memory pool means that either users who care about speedy
confirmation have to pay higher fees, the average actual block size has
to go up or prioritization has to get smarter. If load increases more
then we need more of any of these three tendencies as well. (Note that
the last one is only a very limited fix, because as the high priority
transactions get confirmed faster, the low priority ones take even longer.)
