eclipseのメモリを増やしたい

Posted at

経緯

デフォルトではメモリの割り当てが少ないので、増やす。

eclipse.iniを編集。

eclipse.ini
-startup
plugins/org.eclipse.equinox.launcher_1.4.0.v20161219-1356.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.551.v20171108-1834
-product
org.eclipse.epp.package.php.product
-showsplash
org.eclipse.epp.package.common
--launcher.defaultAction
openFile
--launcher.defaultAction
openFile
--launcher.appendVmargs
-vmargs
-Dosgi.requiredJavaVersion=1.8
-Dosgi.instance.area.default=@user.home/eclipse-workspace
-XX:+UseG1GC
-XX:+UseStringDeduplication
--add-modules=ALL-SYSTEM
-Dosgi.requiredJavaVersion=1.8
-Xms256m  ★ココと
-Xmx1024m ★ココ
--add-modules=ALL-SYSTEM
-Xverify:none
-javaagent:plugins/jp.sourceforge.mergedoc.pleiades/pleiades.jar
  • -Xms:起動時のヒープサイズ
  • -Xmx:最大ヒープサイズ

この二つの値を大きくする。でも大きくしすぎると起動しなくなっちゃう模様。
