View large file more than 300000 lines very slow.

[bitristan]

My macbook has 16G memory and 512G SSD. My emacs was installed by homebrew with --cocoa. I forked your configuration and it's pretty well. But a while ago, when I opened a file which is nearly 9M and
have more than 300000 lines, it's very slow moving around the whole file. I search the Internet and find a library vlf.el but not yet tried. How about your computer and is there any plan to solve this?

1. emacs -nq -Q the-large-file, is it better now?
2. send me the file

[bitristan]

I just use -Q and it's very fluent. But when my emacs was open and use C-x C-f to open the file, can there have some method? I will send you the file.

it's because many major-modes are loaded, send me the file so I can optimize major-modes.

[bitristan]

I couldn't find any way to send the file to you directly. So I put it on my google drive. https://drive.google.com/file/d/0B1QvPWzcQGdqaWt2NElZVDNjNVU/edit?usp=sharing

you can email it to me, gzip it and email to chenbin.sh AT gmail DOT com

[bitristan]

has sent email to you, the file is just a normal log file, please check your email.

[bitristan]

Yeah, it's much better now. But I think it's not perfectly solved. Because the line position on modeline becomes ??. I'll have some try.

it happens when the screen is not big enough to display the line number.

Now you can M-x display-line-number
