Windows
Intel i5-4210U @ 1.70GHz 2.40GHz 8Gb ram
Ubuntu
Celeron N3060 @ 1.60GHz x 2 1.8 GB
It looks as if you are right then Carlton
It's not really a problem, but it would be nice to speed it up if I can. What do you think about the extra WiFi traffic? I think I'll try a USB WiFi receiver to see if that helps. I don't think I can add extra ram to the Linux box.

Now that my new Linux machine is working without any apparent problems, I thought I would do a Bitcoin wallet comparison. I'm using the free WiFi at McDonalds, and both machines are running at the moment. I started the Linux machine first thing this morning, and it was 16 hours behind. I started the Windows machine 2 hours later, and it was 19hours behind. The windows machine finished about 10 minutes ago, but the Linux machine is still 2 hours behind.
Transfer stats -
Windows received 139Mb and sent 3Mb
Linux received 170Mb and sent 8Mb (and has just finished )
Machine specs -
Windows - Core i5 notebook with 2Tb hard drive containing all Bitcoin files
Linux Ubuntu - Celeron with internal SSD for core software, and an external USB SSD for the blockchain files
WiFi runs at just under 30Kb for most of the time, but has short bursts up to 1,000Kb or drops to virtually zero. The transfer histograms for the two machines indicate the same 30Kb transfer for most of the time, but variations are unmatched. The WiFi on the core i5 machine seems to have a greater range.
What do you think is likely to be the reason for the difference in sync' times? My first thought was to blame the SSD, but if this was the case, wouldn't it result in lower activity in the WiFi. My next thought was that the Linux machine has an inferior Wifi processor, and this could be the reason for the larger file transfers if it includes many re-tries.

Thanks for that Shorena.  They've both sync'd now, and went fairly quickly towards the end. I'm quite impressed with the new rig. It's ideal as a light full function notebook with up to 11 hours battery life, and the ability to run a full node with the complete blockchain. |

It seems to have speeded up now. I ran both nodes at the same time, and it only appeared to knock about 2Kb off the speed of each.
Something may be going on around here, because my mobile couldn't connect - it said the service was overloaded. ( that's got nothing to do with the WiFi of course ).

I've got 2 core 0.13.2 nodes.

Thanks Danny - I do tend to watch political stuff on YouTube whilst it's sync'ing. But I would have thought that if it's showing 30Kb, then that should be OK. Your point about processing power is valid as well. Windows keeps adding processes, and they may be messing things up.

My new wallet went from 24 hours behind to 25 hours behind. I switched to the old wallet on my main computer, and that doesn't seem to be catching up either. I'm on public WiFi which is reported to be giving me a 30Kb connection. This has been fast enough in the past, but it looks as if it may be struggling at the moment.
If Bitcoin traffic is going to increase, then I may have to rethink my approach to running a node.

On the face of it, I seem to have got this working. I had a bit of a hiccup because I didn't build the blockchain in a sub-directory, but I moved it, and re-started core specifying the new directory structure. It now running after a bit of thinking, and it's synchronising with the network. It says it is 23 hours behind, and that's probably about right. Lets see if that moves before the end of my coffee. |

Well this has certainly been an interesting experiment. I started the ftp, but that looked as if it was going to take too long over public wifi, and, of course, it's a double operation.
I decided to do a bit of research into the ssd recognition problem in Windows, and I've now got it transferring files. I'll wait to see if Ubuntu can read them, but hopefully it shouldn't be a problem as the drive was set up by Ubuntu.

It's fairly simple. I want to run a full node over public wifi on this cheap notebook. I've removed windows 10 and replaced it with Ubuntu. As it's only got a small internal ssd, I've added an external 256Gb SSD, and I want to copy the blockchain from my other computer onto the external SSD a pain in the exit port, so I'm looking for an easy way to copy the blockchain without introducing Windows restrictiuons on the SSd. I might give up the transfer to the USB stick, and try using Bluetooth tomorrow. The problem with Bluetoth is that it will only transfer files and not directories. Actually, I've just had another thought. I might use ftp to put it on a server, and pull it back from there. |

It isn't the Ubuntu that's the problem. It took about a minute to run the sudo to install the drivers. I'm not sure why they aren't in the basic installation, but they are easy to add, and they seem to work perfectly. Windows 10 is a different matter. It seems to be deliberately difficult if you want to communicate with a different world. I might dump it from the main computer when this one is stable.

Well this was going well, and I bought the Samsung SSD drive. It's preformatted for exfat, and I gather that is the best format for an external ssd. Ubuntu didn't like that, but a quick run of a sudo command soon fixed it, and now it likes the drive. Windows 10 is a different matter - it wants to reformat the drive. I gather that I may be able to get windows to recognise it if I reformat under Ubuntu, and set a partition flag (I forget which one). I'm inclined to forget the idea of using the drive to switch machines, and I'll just use it with the Linux book. Already I prefer the Ubuntu, and I haven't started to customise anything.
The plan now is to copy the blockchain onto a memory stick, and to copy that onto the SSD. Then I can install the Bitcoin core. I'll just check to see if I need to move anything else with the blockchain.

I've got Ubuntu running with everything working, including the WiFi.
I can't use a convential HDD because of the power requirements. If I added one, I'd be no better off than with the other notebook, that has got a 2Tb drive in it. I've got a 128Gb Sandisk stick, and I used that to do the installation. I was going to use that for the blockchain, but I think it's too small. and wouldn't give me any room for growth. I'm interested to see how I get on with the SSD, and how much power it will need.

Thanks, but I'm not going to use 3rd party solutions for this project.
This is going quite well. I had a bit of a hiccup yesterday, as I couldn't download the Ubuntu software. This morning was a different world, and it downloaded in about 15 mins over public WiFi. I tried to install Ubuntu using Yumi, and that was a mistake, as I couldn't get it working, even after messing around with the BIOS. After resetting the BIOS, and rebuilding the USB stick with the standard pendrive installer, everything ran smoothly, and the machine is running well under Ubuntu with no trace of Windows or its spyware.
I'll probably buy the SSD drive later and play with that.

I don't know why you guys don't accept that Satoshi is not a person, it is a dominant family of computers. Bitcoin is part of their attempt to take over the world.

OK here we go with the project. I'm creating the recovery disk at the moment - what a slow process this is, but then I guess it's Windows. I've got a 128GB Sandisk USB drive, and I'm going to try this for the Linux install. It's got a blockchain backup from last January (2016), so I guess I can overwrite that. My next post in this thread will be to say that Ubuntu is up and running hopefully. |

There are some realy good points that have been made. It looks as if the optimum plan is as follows -
- Build the blockchain on a different machine
- Use a memory stick on an USB 3 port rather than an SD card for the blockchain and log files
- Buy a good quality fast memeory stick, I plan to use a 128Gb Sandisk
- Store the wallet and other small files on the notebook hard drive
- Eject the USB stick when core is not running
- Run a pruned node in anticipation of the blocksize increasing to more than 128Gb

OK - a bit more clarification.
With regard to nodes. There seem to be a variety of options, and descriptive names.
1. A node with a complete blockchain and both inbound and outbound connections
2. As above but with only outbound connections
3. A pruned version of 1
4. A pruned version of 2
As I mentioned before, I run a type 2 node on a notebook with a 2Tb hard disk. I plan to copy this blockchain onto a USB stick, and start a new wallet on the Linux computer using the copied blockchain. I have decided to prune this, so I will end up with a type 4 node. I don't have inbound connections because I use public WiFi for this project, and that only allows outbound connections.
Always on is not a possibility because the project is about people on the move or with a mobile lifestyle.

Being a mod id a thankless task. Whatever you do , someone will object and try to trash you.
