Don't close Emacs every time you want to use the shell. Use Ctrl-Z to move Emacs to the background and the <code>fg</code> command in Bash to move it back to the foreground.

blocks|key|1576589|text|检查您的.emacs文件，看看是否加载了不必要的包。加载包可能会花费大量的时间。例如，您可能只想在编辑php-mode文件时加载PHP包。你可以通过安装一个钩子程序来做到这一点，尽管我不确定细节。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1576590|还要确保您正在加载的所有包都已编译(.elc文件)。可以通过运行以下命令编译elisp文件|1576591|emacs+-batch+-f+batch-byte-compile+thefile.el|code-block|syntax|javascript|1576592|编译包的加载速度比未编译包快得多。|1576593|entityMap^0|4|6|1F|8|0|I|4|12|5|0|0|0^^$0|@$1|2|3|4|5|6|7|Q|8|@$9|R|A|S|B|C]|$9|T|A|U|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|V|8|@$9|W|A|X|B|C]|$9|Y|A|Z|B|C]]|D|@]|E|$]]|$1|H|3|I|5|J|7|10|8|@]|D|@]|E|$K|L]]|$1|M|3|N|5|6|7|11|8|@]|D|@]|E|$]]|$1|O|3|-4|5|6|7|12|8|@]|D|@]|E|$]]]|P|$]]

Check your <code>.emacs</code> file to see if you're loading unnecessary packages. Loading packages can take a significant amount of time. For example, you might only want to load the <code>php-mode</code> package if you're editing a PHP file. You can do that by installing a hook procedure, although I'm not certain of the details.

Also make sure that any packages you're loading are compiled (<code>.elc</code> files). You can compile an <code>elisp</code> file by running

<pre><code>emacs -batch -f batch-byte-compile thefile.el
</code></pre>

Compiled packages load much faster than uncompiled packages.

Emacs is designed to run "all the time" (or at least for long periods of time), thus starting and stopping Emacs several times during a day is not recommended.

I would suggest using screen. Screen is a terminal multiplexer, giving you an unlimited virtual terminals in one terminal. 

After installing simply write "screen emacs" in your terminal. Emacs will start as usual, but pressing "c-a c" (that is press ctrl-a and then c) will open a new virtual terminal. You can get back to emacs by pressing "c-a c-a" (that's two times ctrl-a).

You can even detach from the running screen session, the key sequence is "c-a d".

Re-attach to the session by issuing "screen -R" and you will be back where you left. This enables you to start an emacs session at work, detach, go home, and re-attach from home.

I've been running Emacs like this for months in a row.

Here's the official web site: <a href="http://www.gnu.org/software/screen/" rel="noreferrer">http://www.gnu.org/software/screen/</a> but try googling for screen tutorials and howtos

One thing that others haven't mentioned is to include the elisp libraries you use as part of the <a href="http://www.gnu.org/software/emacs/elisp/html_node/Building-Emacs.html" rel="nofollow noreferrer">dumped Emacs</a> to move the library loading time from Emacs startup to Emacs build. It is not for the faint-hearted, but if you load several libraries in <code>.emacs</code> it could win you a few seconds of startup time.

Try using the <a href="https://github.com/jwiegley/use-package" rel="nofollow">https://github.com/jwiegley/use-package</a> macro to define your package loads and customizations. It handles deferred loading of packages for you, making it relatively easy to get good startup times even in the presence of large numbers of configured packages. I have almost 100 packages referenced in my .emacs, but my startup time is under 2 seconds on Linux, and 2.2s on the Mac.

I was trying to solve the same problem, when I came across this question here. I just wanted to add that the problem for me was not because of the load time of emacs lisp packages, but the fact that the host did not have a fully resolved hostname

To check your package load time do 

<pre><code>M-x emacs-init-time
</code></pre>

For me it was 0.3 seconds, and yet the load time was extremely high.
After changing my hostname correctly, it fixed the problem.

To configure your fully resolved hostname edit /etc/hostname, and /etc/hostsfile with:

<pre><code>127.0.0.1 localhost localhost.localdomain
192.168.0.2 hostname hostname.domain
</code></pre>

I would have to check my customization, but there is a package called gnuserve or emacsclient. It migrates a lot so you will have to google for it.

It runs one emacs session in the background. Any further sessions of emacs are essentially just new frames of that session. One advatage is quick startup times for your later sessions.

I use <a href="http://en.wikipedia.org/wiki/Emacs" rel="noreferrer">Emacs</a> v. 22 (the console version, either remotely with <a href="http://en.wikipedia.org/wiki/PuTTY" rel="noreferrer">PuTTY</a> or locally with <a href="http://en.wikipedia.org/wiki/Konsole" rel="noreferrer">Konsole</a>) as my primary text editor on Linux. It takes a while to load up each time I start it though, probably almost a second, although I never timed it. I tend to open and close Emacs a lot, because I'm more comfortable using the <a href="http://en.wikipedia.org/wiki/Bash_%28Unix_shell%29" rel="noreferrer">Bash</a> command-line for file/directory manipulation and compiling.

How can I speed up the start-up time?

How can I make Emacs start-up faster?

Linux

我使用Linuxv22(控制台版本，远程使用或本地使用)作为我在上的主要文本编辑器。我每次启动它都需要一段时间来加载，可能几乎是一秒钟，尽管我从来没有对它进行计时。我倾向于打开和关闭，因为我更喜欢使用Emacs命令行进行文件/目录操作和编译。如何加快启动时间？
