bulk save action performance

[delanym]

Performance is very slow doing a bulk save action on around 18000 java files. The IDE is completely unresponsive.

Triggered via ctrl+shift+a > "Execute Save Actions on multiple files" > "Whole project"

I can see via git console that the plugin is doing the refactorings and saving them. So I guess if I left it alone for a month it would get done.

If its possible to invoke this from the command line like I do with eclipse to format the code - that would be a bonus
(eclipse -nosplash -data /home/delany/eclipse-workspace -vm java -application org.eclipse.jdt.core.JavaCodeFormatter -verbose -config /git/org.eclipse.jdt.core.prefs /git/myprojectdir)
