Here are some logs from a withdrawal from bank.test.taler.net that contains timestamps and useful info. |
|
|
Christian will provide Ivan with a slow Android tablet for testing. |
|
|
I've put an unlocked (just swipe) Android tablet with a horribly slow Taler wallet installed on your desk at the office. |

`getWithdrawalDetailsForAmount` seems to be particularly slow in this tablet, taking a whopping of 3 seconds and 661 milliseconds. (This is the request that runs every time the amount in the field is modified) getWithdrawalDetailsForAmount.logcat (5,457 bytes)

The slow function is the DB transaction in `updateWithdrawalDenomsForExchange`, where there's this TODO: // FIXME: Use denom groups to speed this up. |
|
|
Please also (re)try the initial denominations import, that was also super slow. |
|
|
Importing the database you mean? |
|
|
No, *initial* scan of the withdraw-exchange QR code when we add the TOPS-exchange for the very first time. You'll need to delete the exchange first. |
|
|
Yes, that's exactly what I did. It's in the withdrawal screen where this request is called both at startup and every time the input amount is edited by the user. As per the logs, it's the slow request, all the other ones only taking a few milliseconds. |
|
|
Ok, but in that case it took like 30s, not the 3s for the withdraw calculation... So that should be a different code path that is also slow. |
|
|
It's certainly not 30s, I tested with your slow tablet. |
|
|
It was >> 3s though... |

Here's the full log file for an initial withdraw-exchange: worse.logcat (30,771 bytes)

Analysing the full logs, it can be observed that: 1) Fetching the keys takes 1 second 569 milliseconds. 2) Fetching the contract terms takes no more than 541 milliseconds. 3) updateExchangeFromUrlHandler takes a monstruous 5 seconds 553 milliseconds. 4) updateWithdrawalDenomsForExchange/doAutoRefresh takes 1 second 619 milliseconds. 5) getWithdrawalDetailsForAmount takes a whopping 3 seconds 123 milliseconds. 6) Everything else is negligible. Notably, (1) is much slower than (2). |
