ethereum{"title":"We recommend raising gas limit to 4 million or higher now that the hard forks have completed","version":"1.0","encoding":"plain"}The attacks have subsided and recent hard forks have been enacted. The core developers are recommending that miners raise the gas limit to 4 million or higher and resume accepting transactions if you have stopped. It is a more profitable strategy to increase the gas limit and to accept transactions rather than consistently mining empty blocks. Below are the settings to apply if you choose to raise the gas limit to 4.3 million
geth Mining
> --targetgaslimit 4300000 --gasprice 20000000000
Parity Mining
> --gas-floor-target 4300000 --gasprice 20000000000
A blog post by /u/vbuterin describing uncle rates and transaction fees when mining can be found here. It concludes that accepting transactions with a gas price of 20000000000 as suggested in this post is fairly close to optimal.
If you find that your mining software is mining an abnormal amount of empty blocks please file an issue in the appropriate GitHub repo.
