Performance parsing JSON on Android emulator vs physical device

I'm developing an app which needs to parse at least 20.000 objects from JSON to POJOs so I'm testing JSON parsing times according device's hardware.

Because that, I thought to use an emulator to test different specs. The thing is, using Genymotion or Andy or another emulator, parsing times are extremely low compared to parsing time on a physical device with the same specs.

For example:

HoneyWell E70 (1 core @1Ghz / 512 Mb RAM): 2 minutes.
Custom emulator phone (1 core @1Ghz / 512 Mb RAM): 18 seconds.

Parsing on emulator gives you "unreal" performance times? Or emulator times are "real" and it's just that HoneyWell's CPU really sucks parsing?

I don't know which one is the normal parsing time and, for the moment, I don't have a third device to compare HoneyWell and emulator against it.

Solution

  • It was option 2: HoneyWell's CPU really sucks parsing. I could find a third device to compare and emulator was correct.
