How to speed up Lotus Notes client 8.5x

The first time I migrated MS Outlook to Lotus Notes, most users complain about the speed, and they said that MS Outlook is faster in any operations when compare to Lotus Notes.

I had to agreed with them.

I had to live with it, and thought that because it just they way it is, because Lotus Notes is not only an email client, but also a collaborations tool, that why it is slower compare to MS Outlook.

But I was wrong.

When I brought this up to IBM support, they came with a suggestion that I modified a file to increase the performance of Lotus Notes. And they were correct, with it Lotus Notes performance is a faster than before.

These are the steps:

  1. Close lotus notes.
  2. Open the folder/directory where you install lotus notes client, in my case c:\lotus\notes
  3. Find the file “\Lotus\Notes\framework\rcp\deploy\jvm.properties” and edit.
  4. Within the file, find the line “vmarg.Xmx=-Xmx256m” and change it into “vmarg.Xmx=-Xmx512m”
  5. Within the file, find the line “vmarg.Xms=-Xms48m” and change it into “vmarg.Xms=-Xms96m”
  6. Save the file.

Now, try to run Lotus Notes and see the differences. You can also play the setting, depend on your work load and your RAM. If you have more than 2 GB ram, you can try to increase the settings to:

vmarg.Xmx=-Xmx1024m
vmarg.Xms=-Xms256m

This improvement not only affects windows client, but also Linux or maybe Macs.

Please note that, if you apply the fix pack, the setting will be restores, so you need to re-edit it again.

This also come from IBM support

If you feel that you have a network problem while using Windows Vista or Windows 7, you can follow this suggestion.

Run this command (without the quotes) from command prompt from Windows vista or Windows 7, make sure you run it as administrator.

“netsh interface tcp set global autotuninglevel=disabled ”

This command will disable the windows network auto tunning, see here

And better to apply the latest fix pacth, the latest fix pacth  as I’m writing this post for Lotus notes 8.5.2 is FP3.
