• Install BigProject Generator. Generate a 10000 assets project ([https://github.cds.internal.unity3d.com/unity/com.unity.bigprojectgenerator)]
• Install Search performance package ([https://github.cds.internal.unity3d.com/sebastienp/com.search.unity.performance)]
• Run Menu Tools / ProviderBenchmarks/ adbEnumerateAssets. It takes about 40ms
• Run Menu Tool / Provider Benchmars/ adbPRoviderAllAssets. It takes 30s.

Expected Results: even though the ADB prorvider is doing more than simple ADB enumeration it shouldn't take that much time to execute. Also memory seems to increase a lot. It seems the ADB provider is actually loading the assets.
