thanks for the clarification.
For the record; On the tests I made the income seems to have noticibly improved after I applied the changes indicated in the first post of this thread.
Unless your node is the one submitting the blocks, the changes in the first post have no bearing on your mining income, since it is somebody else's node that has created and submitted the block, and you have no control over whether or not that node has followed the recommendations.
What the first post states is simply that if you increase the transaction fee minimum for any transactions you include in blocks you create, and also increase the size of the blocks you create will translate into blocks containing more transactions with higher fees. Again... just because you're doing it, doesn't mean anyone else is.
What really matters to you as a miner is that your shares are submitted and not DOA or orphaned. That means having a well connected peer. The faster you can get your shares out to the network, the less of a chance you have of them being orphaned. The faster your own node processes shares, the less chance you have of them being DOA.
