找了网上多个修改配置都不生效，最后在安装目录C:\Program Files\JetBrains\GoLand 2021.3.3\bin下看到goland.bat如下代码，直接复制出来保存为bat文件，在代码最后加一条echo %VM_OPTIONS_FILE%查看他的真实配置文件是在哪，再根据echo的文件路径去修改-Xms2048m -Xmx10240m 这2个值
SET BITS=64
SET VM_OPTIONS_FILE=
SET USER_VM_OPTIONS_FILE=
IF NOT "%GOLAND_VM_OPTIONS%" == "" (
:: 1. %<IDE_NAME>_VM_OPTIONS%
IF EXIST "%GOLAND_VM_OPTIONS%" SET "VM_OPTIONS_FILE=%GOLAND_VM_OPTIONS%"
)
IF "%VM_OPTIONS_FILE%" == "" (
:: 2. <IDE_HOME>\bin\[win\]<exe_name>.vmoptions ...
IF EXIST "%IDE_BIN_DIR%\goland%BITS%.exe.vmoptions" (
SET "VM_OPTIONS_FILE=%IDE_BIN_DIR%\goland%BITS%.exe.vmoptions"
) ELSE IF EXIST "%IDE_BIN_DIR%\win\goland%BITS%.exe.vmoptions" (
SET "VM_OPTIONS_FILE=%IDE_BIN_DIR%\win\goland%BITS%.exe.vmoptions"
)
:: ... [+ <IDE_HOME>.vmoptions (Toolbox) || <config_directory>\<exe_name>.vmoptions]
IF EXIST "%IDE_HOME%.vmoptions" (
SET "USER_VM_OPTIONS_FILE=%IDE_HOME%.vmoptions"
) ELSE IF EXIST "%APPDATA%\JetBrains\GoLand2021.3\goland%BITS%.exe.vmoptions" (
SET "USER_VM_OPTIONS_FILE=%APPDATA%\JetBrains\GoLand2021.3\goland%BITS%.exe.vmoptions"
)
)
echo %VM_OPTIONS_FILE%
