FramePack性能优化方案
基于NVIDIA 4090测试数据，通过以下组合方法可将生成速度从2.5秒/帧提升至1.5秒/帧：
- 启用teacache：在demo_gradio.py启动参数中添加–use_teacache=true
- 选择高效注意力机制：安装xformers并设置USE_XFORMERS=1环境变量
- 优化硬件设置：在NVIDIA控制面板中开启GPU高性能模式，设置电源管理模式为”最高性能优先”
- Adjustment of generation parameters：降低潜在空间分辨率(latent_resolution=128)，牺牲少量画质换取速度提升
进阶方案：可使用Sage Attention（约提升15%速度），但需注意其对生成质量的潜在影响。推荐测试生成质量后决定是否采用。
