How can I improve the question How well is the Raspberry Pi's performance?
I do not want to delete it if it can be made better.
At the time it was closed your question was:
Is the Raspberry Pi too good to be true?
The Raspberry Pi motherboard is $25-35 depending on the model purchased. It seems like the Raspberry Pi would be provide poor performance for that price. For such a low price, does the Raspberry Pi work well or does the device have many issues?
There are several problems here.
Firstly, it isn't actually about robotics so it really should have been closed as off-topic and migrated to Raspberry Pi stack exchange.
Sadly if we had done this, it would still have been put on hold due to the other problems. It is simply just too broad. Does the Raspberry Pi work well for what? Does it have many issues when doing what? There is a huge difference between doing some light web browsing or python coding and trying to implement a SLAM system for controlling a mobile robot.
That is why all stack exchange sites prefer practical, answerable questions based on actual problems that you face since Chatty, open-ended questions diminish the usefulness of our site and push other questions off the front page.
Your question is currently:
How well is the Raspberry Pi's performance?
Primarily this still it isn't actually about robotics, so at best it should be migrated.
This is still asking for opinions without any practical focus. As such it would almost certainly be closed over on Raspberry Pi stack exchange for these same reasons. Since I don't want to migrate a question which they would close anyway, I would rather leave it closed here until you have decided whether you can make it into a viable question.
Thanks for your eagerness to improve your question, I hope this answer helps you understand what you need to do to ask practical questions in the future.
