下面的答案建议直接在应用程序安装目录中编辑 .vmoptions 文件.请注意，不推荐这样做，因为它会在补丁更新期间引起冲突.上述方法会在 CONFIG 目录和您的 IDE 安装中创建该文件的副本完好无损.
Answers below suggest to edit .vmoptions file directly inside the application installation directory. Please note that it's not recommended since it will cause conflicts during patch updates. The method above creates a copy of the file in the CONFIG directory and your IDE installation remains intact.
还要注意 Windows 上的 32 位 地址空间限制使得使用大于 750m 的堆大小变得困难.如果您需要使用更大的堆，请确保首先切换到 64 位 JVM，否则IDE可能会在启动时崩溃或在工作中随机启动.
Also be aware of the 32-bit address space limit on Windows which makes it hard to use heap sizes higher than 750m. Should you need to use larger heap, make sure to switch to the 64-bit JVM first, otherwise IDE may crash on start or start to crash randomly during work.
