A lot of GarbageCollector calls before Firebase query start execution
<p>I found that Firebase performs slowly on some query even if it is on a small set of data.
I set Log Level to Logger.Level.DEBUG to see if i can find some information in the log cat.
Here, in the log cat, i found so many GarbageCollector calls befoe the firebase query started. </p>

<p>It causes a relatively long delay ( > 10 seconds ).
I set the persistence enabled to true and the Firebase verson i use is 9.4.0</p>

<p>How can i fix this issue?</p>
