Vim is not performant. Try scrolling in Vim, then try scrolling in Sublime.

Seems fine on my >500Go aggregated log file. Scroll line by line with no issues. Sed and matching is near instant.

What's the issue ?

I'm not sure why you would open a log file with vim, but that's besides the issue. The issue is with 500 line files. Open one up in Sublime and one in Vim. If you only use Vim you'll never discover what it to means to have a performant editor (I've used Vim for ~10yrs and still regularly do).

I have no idea what you are talking about. I opened a 26,000 line file (no I don't want to talk about it). In vim it opened instantly and my scrolling was only limited by my key repeat rate. The scrolling isn't as smooth looking because vim doesn't animate the scrolling between lines. Sublime took 2 seconds to open the same file, and scrolling was smooth.

Maybe you are using to many vim plugins? I'll admit vim plugins are a real problem, the gui rendering desperately needs to be moved to its own thread.

i tried but sublime doesn't work in SSH :(

You're right. Editing a large file with syntax coloring and vim slows to a crawl. I just can't get away from Vim though as it works so well in terminals.

This is mostly to do with the syntax matching, the regexes used for that, and thus ultimately also the implementation of the regex engine (which was more or less swapped in Vim 7.4). It bother me a bit too (but not too much). Perhaps it can be mended, we'll see :).

Vim itself is fine, but the plethora of plugins that a lot of people install can drag it down. Firefox has the same problem with extensions. And it's really not the fault of the base package. It's the plugin developers not doing due diligence, and it's the shear number of plugins making it impossible to test all combinations.

Vim can be blazingly fast and maddeningly slow — it all depends on the plugins you have activated.
