user84047: It has taken 9 and half years to mine all blocks averaging 1 per 10 minutes. 
How long would it take to re-mine all current blocks at current hashing power?

user49354: it would take approximately 9,5 years because it does not matter how many hash-power you have. the mining-difficulty will be adjusted so that in average a new block is still mined every 10minutes also if you get much more hash-power.
