Eclipse very sluggish with large java file [message #87377]

windows task manager is a solid green box in the system tray! I tried
adjusting the Workbench preferences to not 'perform automatic builds on
resource modification' but that doesn't seem to help.

Any suggestions!

Automatic build only takes place if you perform save action. Maybe you
can turn of linked with editor for your outliner (option
is it called somehow diffrent). The option I mean turnes off the outliner
updating if you change cursor location. Maybe that will bring you some
more speed.

Take a notepad/simple editor and split it. Then use the fragments and
edit em. By the way is it a autogenerated file (like JavaCC etc.) maybe
you should work on it. Gosh 13,000 lines - that's totally crazy!!!

Especially when you have such a nice refactoring-tool as Eclipse.

Perhaps it helps to give more memory to the jvm?

I can try that. I already start it with -Xmx256m.

Take a look at (top/taskmgr) to see the memory usage.

Add some crazy plugins and 256MBs are nothing ;)

Does this file contains more then one class?
Yes? Then split it! ;)

I think there are some O(n)>=n

Sure thing. Biggest hitter is a measurement plugin I guess. It's
measuring code quality in the background and connects to a
database server to store the stuff. Seams that it caches most
of the calculates to instantly react on build command.

Well another one is a profiler which gives me a footshot
everytime I profile a plugin collection under development.

Currently I have 1024MB installed and every eclipse session
gets max 512 as memory setting and I have two eclipse sessions
+ one debugsession constantly open. Also a tomcat is meowing
in the background.

Now I guess you know what I mean by crazy plugins ;)

It appears that no one knows why Eclipse is so sluggish. I started on Mac
OS X with Eclipse 2.0 and performance was okay. Migrated to 2.1.1 and
performance was obviously slower, but not too bad. The project has gotten
bigger (50 classes, maybe 3k lines in largest) and Eclipse has gotten
slower. I tried various option settings to no avail. On a whim I
downloaded and installed 2.1.1 again, into a new directory. Performance was
back to the 2.1.1 starting level, but deteriorated again over a couple of
days. It's gotten so that now I can go for coffee while the debugger
single-steps. As you can imagine, this isn't acceptable, so I can either
find a fix (any ideas?) or find another tool. IntelliJ seems to handle this
same project okay, so I suspect there is some Eclipse background activity
that needs to be curtailed to get performance back to an acceptable level.

Sound like you need a new maximum memory setting ;) Performance normaly
decreases over the time you are using eclipse because of histories and more
complex programms to keep in memory. I have a max memory setting of 512mb
and everything works smooth within a project containing a couple of mbs of
source and a lot more libraries attached with it.

So my reflex advice would be: Check your memory setting ;)

I've set the memory setting in the Eclipse 3.0 Mac package,
setting -Xmx512M. Performance improved slightly, but not enough to really
be useful. I'm seeing long delays on single stepping in JDT, long delays in
response to clicking on icons (Resume, Terminate, etc),. Code execution
between breakpoints is very slow as well (it's much faster when running
under control of another IDE like IntelliJ, so it isn't my code ;-) .
