我最近从Eclipse升级到Android Studio，但我并不喜欢这种体验。我比较的是Windows 7 64位终极版，16GB内存，英特尔i7 4770运行NVidia Geforce 780，如果重要的话，我运行的是最新的JDK和最新的Android Studio。
Android Studio在构建项目时非常缓慢，我可以接受，但它也非常消耗资源，有时会使PC速度变慢。
每当我在AS中构建或运行任何东西时，我的PC似乎变得极其缓慢。如果我点击“Gradle build running”旋转器，它也会导致屏幕闪烁，偶尔会让我的第二个显示器空白，我觉得这很奇怪。内存的使用也飙升到3GB，我发现什么都不做就过度了(这是在几次构建后空闲的时候)。
此外，AS底部的面板一直在跳来跳去，这是一种糟糕的用户体验(从Android移动到消息到版本控制或其他任何临时的基础上，这取决于正在发生的事情，这是非常非常恼人的)。
我想知道的基本上是:
1)如何让Android Studio运行得更好?我可能做错了什么，或者错过了一些我不知道的更新，我相信其他人也注意到了这些行为，并找到了一些解决方案。
2)我如何“钉”底部面板，使他们不跳，而是让我，用户，导航到他们当我希望而不是自动切换他们?
非常感谢，如果这不是这些问题的正确位置，我再次道歉。

我使用的是今天最新的稳定版本。这个版本是Android Studio 1.2.2 build # AI-141.1980579，于2015年6月3日发布
这种行为发生在使用Java 7或Java 8时。它似乎与Java版本无关。
我没有使用演示模式。只是普通的观点。
对构建配置进行更改(感谢@Blackbelt和他的回答)似乎对构建有所帮助，但迟缓和一般用户体验等其他问题仍然存在。
建议:
必须说:如果你有任何机会，花一些钱买更好的PC(cpu)，
这是最重要的…
调整:
Some people say, that OS (Operating System) might cause much slowness. For example, XP or LINUX (or etc) was mentioned to perform 70% faster (don't know why..).
Disable VCS by File > Settings > Plugins and disable the following things :
CVS Integration; Git Integration; GitHub; Google Cloud ... things; Subversion Integration; hg4idea;
Editor is a resource eating too (especially on Large Monitors) and slow. Make it much much faster: click Help > Edit custom VM options and add these lines :
-Dsun.java2d.d3d=false
-Dsun.java2d.opengl=true
save it and Restart Android Studio.
If Android Studio has a proxy server setting and can't reach the server then it takes a long time to build and waiting for a timeout. Removing it helps much. File > Settings > Appearance & Behavior > System settings > HTTP Proxy.
Another Useful quote (from article):
Modules are expensive… On my current project I had to build some libraries from scratch and had to fork some that almost fitted my needs but not quite! If that modules are not constantly modified, it’s important to have this into consideration: the time needed to compile them from scratch, or even to check if the previous individual module build is up-to-date, can be up to almost 4x greater than to simply load that dependency as a binary .jar/.aar.
Hint: run the gradle build -profile for an HTML report showing where
the time goes regarding the build process.
Note: keep that “unnecessary” modules in your version control system
for the eventuallity of a quickfix/improvement in that dependency.
In your Gradle build script, use only
specific Google Service, like: compile 'com.google.android.gms:play-services-maps:...'
Instead of full Google Library: compile 'com.google.android.gms:play-services:...'
(Compile time goes from 2 minutes to around 25 seconds).
Gradle configures every project before executing tasks, regardless of whether the project is actually needed for the particular build. In global gradle.properties adding this will help much: org.gradle.configureondemand=true
Surprisingly, some people say , they solved problem by reducing: 1) heapsizes to -Xmx256m (instead of higher values); 2) Emulator Ram-size (from Edit AVD > Advanced Settings);
每天的建议:
不要同时运行多个项目。
使用一次后不要关闭模拟器(每次都使用相同的模拟器运行应用程序;如果你测试大型应用，最好使用真正的手机而不是模拟器)。
每次在模拟器中运行你的应用程序后都清理你的项目-点击构建>清洁项目(或重建)，你可以使用键盘快捷键。

我尝试在相同的硬件上测试Android Studio 3.1.4的速度:Macbook Pro 2011, RAM 4Gb, SSD 240GB三星，Core i5 2.4Ghz。我在这台机器上安装了3个不同的操作系统:Windows 10, MacOS high Sierra 10.13, Ubuntu 18.04。MacOS/Ubuntu上的平均构建时间(运行命令:gradlew clean build, gradlew clean assemblerrelease)比Windows快30%左右。
On my another working machine: Core i5 3.0 Ghz 7400, RAM 16Gb, SSD 250Gb. Build time takes 4.34min on Windows 10 machine. The same project on a little bit slower processor, but with the same RAM and SSD and it is running Ubuntu 16.04 build time takes two times faster!! Well I was shocked with results, but still I choose Windows as development machine, because it's much more comfortable for me to use comfortable and usable keyboard and sotfware than on Unix like systems. And even if I had to choose between MacOS and Ubuntu - mac is really much easier to setup everything, and Ubuntu is too complex to use for usual people. Choise is up to you.
