Note: It can also be seen that the `SLOAD` moves towards the top position. The `GASPRICE` opcode has position one which I believe can be optimized away within the client -- which is not the case with `SLOAD`/`BALANCE`.

Here is another chart, showing a full sync with Geth. It represents the blocks `0` to `5.7M`, and highlights what the block processing time is spent on.
