Dooglus did this for JD after the old wallet became too large. It helped performance, but he had to manually credit users that deposited to addresses in the previous wallet, which is far from ideal.

I do not quite understand this. Does this mean that it is actually the wallet that keeps track of which customer has how much money, by keeping each customer's btc under a separate unique address? That seems quite a bit of a mess since if I get some money out then the change is by default sent back to a new change address and somehow the wallet has to know that it also belongs to me. So it is hard to maintain a one-to-one correspondence between addresses in the wallet and users.  Or you can set it up to send the change back to the same address where the transaction came from?

I understand from his post that this is the date when he tried to withdraw:

2013-10-22 12:22:33   Withdraw

Which means that the backlog is over 2 weeks  Angry

Anyway, it is good to hear that things are moving at least...

Nah. user balances are typically stored in a database that is completely separate from the wallet. The wallet contains all the deposit address as well as all addresses used internally to use funds around. When a user generates a deposit address, it is added to that users account in the database and when deposits come in, the service queries its database to match the deposit address used to a username and updates the balance accordingly.

If you have thousands of users, many with possibly more than one deposit address generated, as well as addresses used for internal purposes and change addresses, the wallet can become huge and apparently this can slow things down considerably.

But then I still don't get the problem. If user balances are stored separately in a data base then one could just send all the btc from the old wallet to a new wallet and trash the old wallet. The only thing is that deposit addresses should be cleared from the data base and new ones have to be generated. Users then should be explicitly warned not to deposit to their old deposit addresses. This does not look like a serious problem.

The other thing is that I thought that it is not only the too many addresses that clog the wallet but also the many separate small chunks of btc that are generated during the long use of the same wallet. Is this the case?

Quite relieved my bitcoins got sent. My initial transaction was Oct 28th.

I made some nice profits on securities in the past but that's it for me now, I won't be touching them for a while.

Did you actually have to log in to WeEx and send it again or Ukyo sent it by hand to your given address where you wanted to send it on Oct 28th?
