Performance Issue: Logseq Freezes When Loading Notes with Multiple Web Images

I created a new Markdown note in Logseq and pasted a block of Markdown code into it. The original code contains 10 web links to images. Ever since pasting it, every time I open this note, it becomes extremely laggy! I cannot scroll up or down, let alone edit the note.

In the Task Manager, Logseq’s

CPU usage is hovering around 15%, and its power usage is marked as “Very high.”

Here are my PC specs:

  • Device name: DESKTOP-B3N8ICK
  • Processor: Intel(R) Core™ i7-6700 CPU @ 3.40GHz 3.40 GHz
  • Installed RAM: 8.00 GB
  • Storage: 238 GB SSD SAMSUNG MZNTY256HDHP-00000
  • Graphics Card: NVIDIA GeForce GTX 1070 (8 GB)
  • System type: 64-bit operating system, x64-based processor
  • Pen and touch: No pen or touch input is available for this display

A screenshot of the Task Manager is in the attachments.

Given the current situation, what methods can I use to replace the web images in the note with image files stored locally on my computer’s hard drive? I want to test if replacing the web images will solve the Logseq lag issue!

Just to add, the .md file is 685KB in size. I am currently not sure how to upload this file directly to the forum. If this file would be helpful for troubleshooting the issue, I would be happy to provide it to the developers for analysis. Please let me know the best way to send the file to the development team!

Update (July 12, 2026):

  • OS: Windows 10 Home China, Version 22H2 (Build 19045.7417)

I have deleted the problematic note from Logseq (including the corresponding Markdown file in the pages directory). I then removed all URL links from the source Markdown code and pasted the cleaned code back into Logseq. However, the lag persists. This suggests that the performance issue is unrelated to the hyperlinks in the Markdown.The Markdown file contains a total of 3,671 lines.

I hope this information is helpful for debugging.
