You are here because Lotus Notes is working very slow. Well, this is because the default memory limit is too low. In order to fix this, you have to do the following:

1. Close lotus notes and zap it, to be sure it is closed indeed.

2. Check for jvm.properties in the following path:
- if Lotus Notes 8:/opt/IBM/lotus/notes/framework/rcp/deploy/.
- if Lotus Notes 9:/opt/ibm/notes/framework/rcp/deploy/.

3. Open jvm.properties and search for: vmarg.Xmx=-Xmx256m
Replace it with vmarg.Xmx=-Xmx768m and save the file.

4. Open Lotus Notes and feel the difference.
Of course, you can give more memory if you want. The end!
