Blockchain download is confusing fast

[Emilstud]

Hi, I started a full node 20 minutes ago. I forwarded port 8333 tcp and the download is very fast. After 20 minutes I was at block 135100  
I download around 300 blocks per second is this normal with a 400Mb/s Down and 40Mbs Up connection ?

Yeah. I think it's very fast to sync up to the moment when blocks start to get full.
Maybe in a few 10's of thousands of blocks, maybe even in 100's thousands of blocks, but at some point it's gonna get slower.
Good luck and be patient.

Yes, It goes amazingly fast to start with and then botttlenecks from about the time I starated (2015). The last years' worth of blocks are really slow also.
Your computer is fairly fast though as it seems so it shouldn't take you longer than a few days to get the entire blockchain.

That's not surprising considering your fast internet bandwidth unless, your PC got some bottlenecks like Low Ram and Slow Disk I/O which can potentially slow it down by half to quarter.

If you're using a SSD, you might wanna move the data.dir to a Hard Disk since it looks like a waste of space for a premium storage.

This is not that fast.
The first 120,000 blocks are contained in a single blk file (128M) because most of them are empty: Most do not include any transaction beside coinbase. In fact, at this point, you downloaded the 2 first blk file at this point, which is 0.1% of the whole blockchain (there is ~1300 block files as of today). As you'll meet bigger & bigger blocks, the process will go slower & slower.
