I just took an omnibus and merged it so the text would be split into three parts:

1930s-1960s: ~2.6MBs
1970s: ~3.1MBs
1980s: ~740KBs

When you have the larger HTML files open in Code View, you can feel noticeable slowdown. Definitely opening/closing menus, and anything you click on becomes sluggish.

This is Windows 10, 64-bit, Sigil v0.9.9 (no funny business, just the official download).

The only reason I first jumped to the "large HTML issue" is because there were a handful of times I opened up hideously coded HTML files (think InDesign output), and Sigil was brought to its knees. I tend to open those in Calibre's Editor first, clean it up, then do my finalizing in Sigil.

I've noticed the sluggishness really creep in with HTML files that are >~2MB mark, and once they are split down into more reasonable chunks, Sigil handles them perfectly fine.
