[EP-tech] Manage deposits page loads very slow



Enable sql logging on mysql and write down the queries it does when 
using Manage Deposits. Then disable logging and you can test directly 
the queries looking for mysql bottlenecks.

Is the disk enough fast in the new vm? Is there any difference if you 
shut down the indexer? Did you migrate also the index database or the 
indexer is still running to reindex everything?
