BBEdit is my weapon of choice for reading massive log dumps and database dumps for support at $DAYJOB. It does not seem to ever choke no matter how many hundreds of megabytes if text I need to plow through.
That and random snippets of text that live as
unsaved documents for days to months.
BBEdit is a big misfit for me and how I use editors. It’s great at transforming text and zillion of other features but I get my work done in VSCode or PyCharm. My true preference was Atom. RIP
Even with this all, I still install BBEdit on every device I can.
BBEdit was known for that in the past, but it's a weak point these days. It definitely has an upper limit on filesizes and will "choke" on large files (probably only slightly larger than the log files you're using it for).
Other apps are much better at large files. The APFS filesystem has a maximum file size of 8 Exabytes and plenty of other text editors can handle file sizes that large without any issues.
