- 📋 The video provides a step-by-step guide on how to install a new version of KY, including unzipping and placing it into a designated folder.
- 🌟 An important tip is given to add '--verbose' at the end of the Nvidia GPU bat file to help with debugging and understanding what KY is doing.
- 📂 Instructions are given to modify the 'extra model path.yml' file to point the new KY install to the folder containing the existing models.
- 🔄 After starting the server with the new setup, it is noted that the load times are significantly improved, with the interface loading in microseconds.
- 🖼️ The video demonstrates the use of SDXS (an imaging technology) to generate images quickly, with the new setup allowing for faster rendering of images.
- 📈 Comparing the old and new installs, the video shows that the new install with fewer folders and a clean setup can generate images in 0.09 to 0.10 seconds, a notable improvement.
- 🚀 The video concludes by encouraging viewers to experiment with the new workflow, even on less powerful computers, for improved performance and faster render times.
Q & A
What is the main issue discussed in the transcript?
-The main issue discussed is the slow loading time and performance problems of an existing Confy UI installation, specifically in the browser, which takes up to 5 seconds to load the GUI.
What is the suggested solution to the performance problem?
-The suggested solution is to kill the current server instance, download a fresh copy of Ky, and properly configure the new installation to use the existing model files from the old installation.
How can one identify the function causing performance issues?
-One can use developer tools to select the function that's currently causing trouble, which can help identify the source of the performance issues.
What is the role of SDXS in the transcript?
-SDXS is used as an example of a technology that can quickly generate images, albeit with a lower quality. It demonstrates the potential speed improvements after resolving the performance issues.
What is the significance of disabling previews in the manager?
-Disabling previews can be a temporary workaround to improve performance, but it is not a permanent solution as the previews are still useful for users.
How does the speaker propose to find the path for the models used by Ky?
-The speaker suggests using the command line parameter '--verbose' to have Ky output the paths it's using for models, which can help in troubleshooting path-related issues.
What changes were made to the 'extra model path.yml.example' file?
-The '.example' part of the file extension was removed to convert it into a regular yaml file. The speaker then uncommented lines of code and specified the correct base path where the existing models are located.
What was the result of the new Ky installation after the changes?
-The new Ky installation loaded instantaneously compared to the regular version, and it was able to find and use the specified model paths, resulting in improved performance and rendering times.
How much faster is the new Ky installation compared to the old one?
-The new Ky installation reduced the image generation time from an average of 0.19 to 0.20 seconds in the old version to 0.09 to 0.10 seconds in the new version, achieving nearly 10 frames per second.
What is the benefit of using an empty latent image batch?
-Using an empty latent image batch allows for processing 100 images at once, which can significantly increase the speed of image generation, although the quality may still be compromised.
What is the final recommendation for users with performance issues?
-The final recommendation is to follow the outlined workflow, which involves a fresh installation of Ky and proper configuration to utilize existing model files, ensuring improved performance and usability.
