Why does Bitcoin-Qt takes weeks to sync?

I've been syncing the Blockchain from a bootstrap.dat file over 3 days now...
It's not even from the network, but why is it so slow? I have a Gigabit internet, and the compiled chain just downloaded in 10 minutes

Because the file is too big , and I'am not sure if you are the same person but I guess I told you last time to not use Bootstrap.dat anymore that file is outdated and beside ... new versions of Bitcoin Core now are doing faster so it's better to download using the program itself instead of torrenting.
If you can't handle waiting too much time , then you could simply switch to SPV wallets (e.g Electrum , Multibit HD)

I don't have much experience bootstrapping, but I know that I recently downloaded a fresh install of Core to test how long syncing would take via the traditional network; what I found was on my internet of about 1MB/S it took me about 10-Hours to fully download the blockchain from start to finish. I suggest you just do it the old-fashioned way.

The data must be verified that is why it is no longer suggested to use the bootstrap.dat. You just waste time because you first download and later verify instead of doing both at once.

Anyway. The main bottlenecks besides your internet connection are CPU and HDD. Either is slow.

So I am now downloading from the network, to an SSD drive, Gigabit internet and 4 Cores dedicated to Bitcoin-Qt
