On one thing only no more than 15m. Multi tasking I can stay indefinitely but degrading in overall performance.
Optimal? 45m + 15m break

I feel very much the same way. I find it difficult to stay highly concentrated for longer than 45 or 60 minutes. Sometimes with complex questions, however, only 20-30 minutes. I like to leave the screen during the break. Walk a little. Drinking water is also good.
