Hello, could anyone help me out with this?

The problem I'm having is the wallet taking too long to refresh the blockchain.... Since I like to make new wallets for each significant transaction, and each time I do and need to import the new generated paper wallet into the Cli wallet, the block refresh for the new wallet takes over 52 minutes. As you can imagine this is taking up a fair amount of time when I have to do it for every major transaction I make.

There must be some way to speed up the Refresh sync in the electroneum/monero simplewallet

Here's an example with a testing purposes wallet, check the time in windows...

I'm wondering what the bottle neck is here that's causing it to take so long, My Ryzen 1600 cpu is only at around 14%, and it's not even pegging one core at 100% so it's not a CPU or singlethread bottleneck..

I have a Samsung 850 pro 256gb SSD, and it's using hardly any disk speed so it's not a disk access bottleneck..

It's only using about 170ish MB of ram....

So all I can think of is it's a network/internet bottleneck of some kind.....

There should be a way to download the entire Electroneum blockchain and have the wallet scan that for transactions upon creating a new recovered wallet using keys , using the fast SSD rather than slow network....?

I've read a little on this subject concerning monero, which electroneum is a fork of, anything that works for monero should also work for electroneum.

Here for example it mentions downloading the blockchain...
https://www.monero.how/tutorial-how-to-speed-up-initial-blockchain-sync
However, I've not yet found how to download Electroneums .raw blockchain data from a trusted source as is available for monero...
And this seems for the most part only be for speeding up the Daemons initial Synchronization with the blockchain rather than the blockchain refresh upon creating a new wallet....

Anyone have any ideas? Thankyou in advance :-)

The bottleneck is the offline wallet. Because an offline wallet does not know on which height of the blockchain it was created. So a wallet needs to sync all blocks on the first time (this is not the sync of the blockchain).
You can use the simplewallet for your wallet creation it should be much quicker. Or try out my GUI wallet, which is also based on the simplewallet and wallet-rpc: https://github.com/XzenTorXz/ElectroneumGUIWallet
If you want to throw hardware on it its cpu power you need.

I disagree that it's a bottleneck. No sure where you get your info, but new wallet did sync in 7 minutes to the while blockchain. If you know when you generated the wallet you can custom sync it from your time or from 0. No problem with that.

I'm not sure what information you mean. Anyway you're right you can sync it from a specific point in the blockchain if you know the creation time, but in a normal generated cli wallet its saved automaticly (on the exact height). Based on the screenshots its starting to sync at 0. I'm not saying its a bottleneck in general, but since he asked for a bottleneck in his specific situation I would say thats it. And the easiest solution to fix it, is to use another wallet then the offline wallet. If you want to have the full security, you need it to run the offline wallet on a computer who never sees the internet anyway. In this case the time needed to sync the wallet should be the least hustle.

Btw. I just synced a offline wallet and it took around 15min.

The next optimization is to use a remote rpc node (so you dont have to sync the blockchain yourself). But I would wait with this till an official trust-worthy node is online.
