[Gambas-user] Performance figures for various ways to do reflective method calls

[Martin Fischer]

Hi fellow gambassians,

I was interested in the performance of reflective method calls in
gambas. I tested:
- direct (early bound) method call
- reflective via Object.Call
- reflective via gb.eval
- reflective via Variant

Here are the numbers:

Main.Main.11: Start method direct call...
Main.Main.16: Done in 540ms
Main.Main.18: Start method reflective call...
Main.Main.23: Done in 4135ms
Main.Main.30: Start method eval call...
Main.Main.37: Done in 3469ms
Main.Main.39: Start blind method variant call...
Main.Main.46: Done in 1185ms

The absolute numbers are not relevant. These figures answer the
question: "how much slower is reflective call compared to direct call".

Tiny Project is attached, if you want to reproduce.

Regards
