I just got a new laptop, with plenty of hard drive space, so have started with bitcoin core 15.1, as per the instrutions at https://bitcoin.org/en/full-node#ubuntu-1610.

It has only been syncing for about 12 hours and already states that the estimated time left as 22 hours, 5 years and 15 weeks behind. I thought syncing was supposed to take at least a week! It took about 10 days last time I did it 2 years ago.

So of course, I'm a wee bit suspicious, and paranoid.



DSL speed test: 1.2Mb/s download, 0.5Mb/s upload
Running Ubuntu 16.04, with 32G RAM,  Intel® Core™ i5-8250U CPU @ 1.60GHz × 8, and a solid state drive. Yes I know that's high spec, but still, thought I should check.

Thanks

If your new laptop has an SSD, a decent processor (i5-i7) and sufficient RAM, ~24 hours sounds about right... IIRC, somewhere around core version ~0.13, there was some kind of rewrite of some of the sourcecode with a result of a speedup while syncing....

OK, thanks. I never would have imagined that running a full node could be so easy. Craig fakesatoshi Wright vibez!

It all depends on the bottlenecks... The io of your disks, the amount of ram, the number of cpu threads, the clockspeed, your internet connection... If you have little or no bottlenecks, the syncing is indeed fast enough...

Anyways, if you downloaded bitcoin core from the official repo and checked the signature and you're connected with enough peers, there is little to worry about in the first place Smiley

The latest core seems to be a lot more efficient.

However, I seem to be having some problems with Windows 10 after the latest upgrade. Sometimes it doesn't find any peers to use, and sometimes it works in burst mode with long gaps between activity. I've more or less decided to revive my old Linux wallet, and move everything into that.

Bring up the Windows Task Manager the next time it seems to be slow.  Each time this happens to me, Bitcoin Core is driving the DASD at 100%.  I suspect it is LevelDB compacting its database.

That happened at version 0.10. Since 0.10, syncing the blockchain has gotten much faster. Of course there are performance improvements that happen with every major version that make syncing the blockchain faster and faster.

Thanks for the suggestion. I've got a netbook running Ubuntu, and an additional external SSD. I ran a second node on it for a few months, but I decided I didn't really need two nodes. I've more or less decided that I'm going to migrate to the netbook for most of my admin and financial work, despite it having a smaller screen. Another incentive is that Brackets ( which I use for web site maintenance ) has released a version which is fully compatible with Linux.

Oh, you're lucky, in my case, the synchronization will take more than a week. One of the disadvantages of storing the database simultaneously for all users.
