Description

Hello everyone,

For the past few days, when I restart Comfyui after stopping it, generating an image with an SDXL-based checkpoint takes an incredibly long time.
If I restart my computer, the initial launch of Comfyui does not have this issue.
Generating an image from a model based on SD 1.5 does not have this problem either.

Here is the normal result in my console:

`100%|██████████████████████████████████████████████████████████████████████████████████| 25/25 [00:14<00:00, 1.76it/s]`

And here is the same generation after cutting and restarting Comfyui:

`100%|██████████████████████████████████████████████████████████████████████████████████| 25/25 [14:15<00:00, 34.23s/it]`

When Comfyui runs for the first time after a restart, at the time of initiating an image generation, I see the following lines in the console:

```
model_type EPS
adm 2816
Using pytorch attention in VAE
Working with z of shape (1, 4, 32, 32) = 4096 dimensions.

Requested to load SDXLClipModel
Loading 1 new model

```

But after cutting and restarting Comfyui, I only see the following lines:

```
Requested to load SDXLClipModel
Loading 1 new model
Requested to load SDXL
Loading 1 new model
```

Does this indicate any particular issue?
I updated Comfyui today, but the problem persists.

Thank you for your help!
