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 Shocked

I download around 300 blocks per second is this normal with a 400Mb/s Down and 40Mbs Up connection ?

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.

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.

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.

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.
