How to make the Notes 8 client fly under Ubuntu (updated)

This is a rewrite of the same tip for Windows.  All credit to Andrew Pollack and the others who have blogged the Windows version in the past.

To implement the same trick under Ubuntu, make sure you have the Notes client closed down, then open up a terminal console and enter the following:

gksu gedit /opt/ibm/lotus/notes/framework/rcp/deploy/

You'll need to enter your superuser password to edit the and save the file.  Find the vmarg.Xmx parameter, which should be easy enough: it's the first parameter in my file!  Now replace the 256 with 768 if you've got 2 Gig of RAM, or 1028 if you have more than that.  File->Save and you're done..

It makes quite a difference in the speed of the client.  I tested on 8.5.1 under Ubuntu Karmic (9.10).

Update 26/11/2009
Also on Andrew Pollack's post (see link above) was a comment that altering the vmarg.Xms parameter might give an additional speed boost, although the suggestion was that this mainly benefits Sametime.  I changed that parameter from the default of 48 to 768 on my own PC, and yes, I think there was an extra speed boost noticeable.  (Thanks to Lars, for commenting on this post).

And for added speed: add the vmarg.Xms parameter (see comments on Andrew Pollack's blog)

It is the starting size of the heap. Start equals max means no growing to be done.

Also: Do not jack the heap space up too high without testing. My client gets unstable at higher numbers so I just put in 1024.

Thanks, Lars. I've updated the post with your info on the vmarg.Xms parameter.
