Summary0008917: Withdrawal process is slow for new exchanges
DescriptionIt has been spotted that withdrawing from new exchanges takes significantly longer in Android when compared to withdrawing from exchanges already known by the wallet. The same is not true for iOS, even in older hardware.

Investigate why is this happening,
- is it the UI not responding to certain notifications?
- is the native cURL client doing something inefficiently?
- is it the spirits playing tricks on us?
TagsNo tags attached.

Apparently, the major bottlenecks are the multiple HTTP requests that result from withdrawing from a new exchange:

Almost seven whole seconds are spent entirely doing HTTP fetches!

Indeed, the speed went from ~7 seconds to ~2, sometimes even less than a second.

As this ticket only covers the investigation part, I will close it now that we have results.
