Android studio 1.0.2默认最大内存是750M，这样跑起来非常的卡，难以忍受，机器又不是固态硬盘，最后发现，这个默认值是可以修改的，在android studio目录下找到：studio64.exe.vmoptions文件，绿色部分为修改的参数（-Xmx1050m)，将默认参数修改为1050MB，这样跑起来就非常流畅了，如果觉得还是不够流畅，可以改得更高：

默认值：-Xmx750m

#-Xmx750m
#-Xmx4096m
-Xmx2048m

http://stackoverflow.com方案：

studio64.exe.vmoptions文件

-Xms256m -Xmx1024m -XX:MaxPermSize=350m -XX:ReservedCodeCacheSize=96m -XX:+UseCompressedOops

或者

as per suggested from answers in Android Studio - How to increase Allocated Heap Size

Additionally you may want to add

dexOptions { javaMaxHeapSize "4g" }

我本机的文件studio64.exe.vmoptions
