在上网本上 PhpStorm 非常缓慢和迟缓，优化 IDE 的响应能力？

我最近从 PhpStorm 6升级到了 PhpStorm 7。很高兴看到所有的改进，但它运行速度非常慢，在我的低功耗上网本。输入和查看文本之间的延迟通常为5-6秒，并且随着行数的增加而变得更糟。现阶段无法使用。

如何提高 IDE 的一般速度和响应能力？

Edit 2017: You may first want to try experimenting with allocating PhpStorm some more RAM if available. Do this by

  1. Going to Help -> Edit Custom VM Options
  2. Change -Xms and -Xmx to be something reasonable for your hardware. I have -Xms512m and -Xmx2048m on an 8GB RAM laptop.
  3. Restart PhpStorm.
  4. If you want to see how much RAM PhpStorm is currently using, you can go to File -> Settings and search for and enable show memory indicator.

Original answer: I made some changes to increase the responsiveness of the IDE. I'm sure there are more things one could do, but I found these to improve the performance to well within usable margins. From most effective to least:

  1. Disable language injections: File -> Settings -> Language injections. Untick as many boxes as you're comfortable with. HTML was the real killer for me.
  2. Disable inspections: File -> Settings -> Inspections. Untick as many as you don't need.
  3. Disable unused plugins: File -> Settings -> Plugins. Untick unused.

These changes brought down both the startup time and significantly increased responsiveness of the IDE in general.

Add these to your phpstorm.exe.vmoptions or phpstorm64.exe.vmoptions file, at the bottom:

-Dawt.useSystemAAFontSettings=lcd
-Dawt.java2d.opengl=true

Solid speedup to the point that the editor is now actually usable.

I will for the life of me just never understand why people create editors in Java.

If you need to speed up PhpStorm right away, turn on Power Save mode. (File > Power Save Mode or using "Hector the Inspector" icon in the IDE status bar). This mode turns off on-the-fly code inspections This way you can finish what you have started, and later decide what code inspections to deactivate.

Try removing unnecessary files from your project. I had 3k+ *.html log files inside my project and that slowed down typing terribly when the 'Project' tab was open. (Hiding the project tab or turning off the PHP Plugin does also speeds up PHPStorm, but obviously those are not viable trade-offs.) (I'm using PHPStorm 2016)

OUTDATED IF YOU USE A VERSION MORE RECENT THAN 2017.1 :

The most effective way to speed up new phpstorm version is an experimental feature that is going to be shipped by default in phpstorm 2017.1. Until that you can activate it on jetbrains products (webstorm, phpstorm etc.)

Click on Help => Edit custom properties
Add editor.zero.latency.typing=true
Close and open again the application.

For me the change typing is not laggy anymore. Other tricks didn't helped me or not in a noticeable way.

In my case, PhpStorm wasn't slow at all - a bug in my monitor driver introduced severe lag, and it just happened that I dedicated that monitor to PhpStorm. If you've read this far, try PhpStorm on a different monitor, it would've saved me a lot of time.

It is possible that it will help to increase the maximum memory allocation for PhpStorm beyond its default.

For mine, it was capped at 2GB. I know you asked about a windows machine, but for mac users reading this, you can change this by opening PhpStorm without opening a project. Then hit Configure > Edit Custom Properties and change the xmx value to a higher limit.

Try to exclude the C:\Program Files\JetBrains\PhpStorm 2020.1\plugins\ folder to the windows firewall exclude directories, that will make the phpstorm run faster and indexing will be quick.
Windows firewall thinks that malicious software has been installed with lot of jar files. This solution has worked for me. But I have excluded my project laravel folder too

Possible Solutions

  • Use and older version of phpstorm that your machine fully supports
  • Disable the unwanted plugins
  • Disable the unwanted inspections and intentions
  • Disable the unwanted browser support by pressing ctrl + alt + s then Tools > Web Browsers >
