Very slow processing many transactions

[sashazykov]

Opening a big wallet containing many transactions, as well as doing any action like switching tabs, opening transaction preview, closing it, changing transaction amount etc freezes Electrum for several minutes. It now takes about 10 minutes to open a wallet, create a transaction and broadcast it. It was fast before.

Electrum 3.0.5, MacOS

Can you be a bit more specific about the number of transactions?

Upgrade to 3.1 There have been performance improvements since 3.0.5

How can I get the number of transaction using console? I only know how to get the number of addresses which is about 6000.

@AbdussamadA Thank you, it's faster now. It still takes some time to open the wallet though, and it slower than it used to be. I downloaded 3.1.1 two weeks ago, and forget to install.

You can create a new wallet via file > new/restore and move your coins there. Then once that transaction has confirmed perhaps you can share your old wallet with the developers so that they can look at optimizing Electrum for large wallets? I know @SomberNight was looking for a large wallet. I think even a watch only wallet will suffice i.e. if you shared just the master public key of your old wallet that may be enough (wallet menu > information). Of course only do this if you don't expect to receive any coins there in the future.

@AbdussamadA I can share a master public key to some developers. @SomberNight are you interested?

[SomberNight]

Yes I am. An xpub would be welcome. See email in my github profile.
