RAG API taking extremely long to process documents over 1mb?

[ggomp2885]

What happened?

When I upload a 1.3mb pdf file as a test, Its taking over 1 hour or more to get into the rag database. And its not letting me cancel the upload once it starts, so the file is just stuck sitting there for 1 hour, blocking any other file from being uploaded in the UI.
I have to force-kill the enitre LibreChat app and restart it to have this reset.

This makes uploading any kind of decent length document, just not usable at all,
is there a setting that I am missing?

Steps to Reproduce

1. Open LibreChat
2. Set embedding model to: Azure, "text-embedding-3-small"
3. Attempt to upload a 1mb or larger pdf file into the rag_api

What browsers are you seeing the problem on?

Chrome

This is not the expected experience at all, I can upload 10+ mb PDFs rather quickly. Really the main thing that affects upload time is the amount of text content from the files, no matter what size or file type it is.

Is this a text "heavy" PDF you are trying to upload? Are there any other files that work for you?

First be sure everything else is configured right, too: https://www.librechat.ai/docs/configuration/rag_api

Hey Danny,
Thanks so much for your response!
Here is the example we are working with,

Even with just the first 5 pages of this document, It is taking 3min 30 seconds to get into the rag_api,
Example here: first_5_pages.pdf

Whereas, Chatgpt.com (as a reference point) can upload the same 5 pages in 1 second.

Attaching my both my LibreChat .env file and my rag_api .env file here,
librechat_env.txt
rag_api_env.txt

We are running this locally on a very large server, using the "npm run backend" command,
Would you expect this to make any difference in the rag_api speed versus running it as a docker container?
Is 3min 30sec for 5 pages of text the expected experience?

No it's not expected at all, watch my video, it takes approx. 1 second as well with the pdf you attached. No clue what the bottleneck is for you
