Performance Discrepancy: Lower FPS on RTX 3090 Compared to Reported Results

## Environment
GPU: NVIDIA RTX 3090
VRAM: 24GB
Operating System: Ubuntu 20.04
Model: sam2.1_hiera_tiny.pt

## Issue Description
I'm experiencing significantly lower inference performance compared to the paper's reported results. While the paper mentions achieving 47.2 FPS on a single A100 GPU, I only get around 25-26 FPS on an RTX 3090. And I do the inference with prompting only one object for the first frame.

## Questions
Is this performance difference expected given the hardware differences (RTX 3090 vs A100)?
How many objects are selected for the first frame?

I would greatly appreciate any guidance on optimizing the performance for my setup.
