How to speed up your Lotus Notes performance by tuning the Java Virtual Machine (JVM )

Lotus Notes uses Java Virtual Machine (JVM) for processing of Lotus Notes applications and plugins.
The Lotues Notes client configuration usually has a standard value that defines how much megabytes of RAM Lotus Notes can maximally use for the JVM.
The value for PCs with more than 2 GB RAM is often set too low, as it should be approximately 1/3 of the amount of PC RAM (default value = 256 MB, but should be 768 MB).

How to change this:

Step 1:
Shut down Lotus Notes.
Make sure no processes are running in the background, run this command from Start -> Run
Type C:\notes\nsd.exe -kill (use the path Lotus Notes is installed in)

Step 2:
Find the file "jvm.properties" file (its location depends on your Lotus Notes version):
In Lotus Notes version 8.5.x it's C:\Notes\framework\rcp\deploy\ (use the path Lotus Notes is installed in)

Step 3:
Open the "jvm.properties" file in a texteditor like notepad.

Step 4:
You will now see a text surrounded by a lot of pound signs ####
The first 'property' after the last # sign is:
vmarg.Xmx=-Xmx256m
This is where you must change 256m to 768m (i.e. 256MB RAM to 768MB RAM)
vmarg.Xmx=-Xmx768m

Step 5:
Save your changes and close the file.
Now start Lotus Notes and should now load a lot faster already at password prompt and afterwards for opening workspace, mailbox etc.
