Ability to pause bitcoin miming while running the gui

[ScottDeans]

When i was testing bitcoin i kept running low on physical memory so i was not able to launch the app, so it would be good to have the ability to run bitcoin gui without the need to have its mining running,

You almost certainly do not have a miner running when using the Bitcoin GUI (unless you called the setgenerate RPC, or started with the -gen command-line option).

Bitcoin Core implements a full node, which validates all transactions on the network (including all of history, when it first runs). Likely the load on your system you are seeing is just due to work for this validation.

If you're not willing or not capable of running a full node due to the resources it requires, you can use different Bitcoin software with different security models.

It may simply be that your bitcoin client is downloading the blockchain... which is huge. I doubt that you are trying to solo mine with your cpu lol, if so, please quit that ;)

If the load from catching up is too high for your system, starting with -par=1 may help.
