I'm syncing the bitcoin 0.17.1 blockchain from the beginning on Ubuntu 18 using Bitcoin Core Qt gui client. Is there a way to see the download speed of the Bitcoin Blockchain and how much time I have left to get it fully synced?

1Do you care about download speed (Mb/s) specifically? Or just 'time until it is synced'? With a fast internet connection, CPU is usually the bottleneck to getting synced.– chytrikJan 1, 2019 at 0:19

If you care about overall sync performance, the download speed is usually not the bottleneck.
If you want to calculate your pure download speed, you can use getnettotals. There is a value totalbytesrecv (amount of bytes received since the Bitcoin Core instance has been started).
You can calculate the speed by reading the sync start time out of your debug.log (or you eventually wrote down the sync start time manually).
But be aware that the CPU intense validation of blocks may have (very likely) throttle your download.

2@Patoshi You should also configure bitcoind to actually use that memory, with the
dbcache=config file entry. Jan 2, 2019 at 15:08
