Performance issue between maui and xamarin - liteDB

[LukasKuchta]

Hello, we are porting Xamarin app into Maui/.net7 and we have issue with performance. Code is same "only" platfrom is different.

Db has 30K records.
xamarin - read all => 20s
maui - read all -> 80s
windows - xUnit test -> super fast

I tested it on Android. iOS will be later.

What can be problem with it any .net7 features ... ? Or any advice for debuging this behaviour ?

they are all test at release? net7.0-android still use mono, i don't think it's performance is lower than xamarin.android, you can create a simple sample to test, if it is lower, create issue at xamarin-android or litedb, not maui

@xtuzy

We made small sample apps. Empty no unnecessary code here.

And result is:
MAUI (net7.0-ios):
Upserted 25000 items in 50.0988223
Selected 25000 items as TeamItemDto in 30.6884797
Selected 25000 items as Bson in 14.0719025

Xamarin.iOS:
Upserted 25000 items in 32.9143934
Selected 25000 items as TeamItemDto in 6.9651505
Selected 25000 items as Bson in 4.4160259

Can you someone explain me what is wrong? Any optimization settings? It seems MAUI problem no liteDB.

@xtuzy there is the source code: https://github.com/LukasKuchta/XamarinMauiDbTest simple maui and xamarin app.

and there are some numbers
https://github.com/LukasKuchta/XamarinMauiDbTest/wiki

We added the SQLite for comparsion and issue in performance is visible too. Seems no db engine problem.

MAUI performnance is very bad against the xamarin. Thanks for check.
