Further info:
I minimize fldigi and usage goes down to 2.7% for fldigi and 3% for Xorg
on local monitor.
With a VNC session: fldigi is 2.7% and Xorg is 11%.

I'm seeing about 5% for fldigi 3.10, and about 32% for Xorg while
running a VNC session on the server.
It stays about the same when I kill the VNC session and use the local
monitor.

Upgraded PI4TUE to fldigi-3.11.1
The server was still running with 3.04, because there is an anomaly
in fldigi-3.10, which eats 95% CPU on the server. 3.04 took only 5% CPU.
So I was eager to install fldigi-3.11.1. It turned out that also
3.11.1 eats 95% CPU, resulting in problems to decode a PSk250 stream
which happens if I try to upload an email with an attachment.
Next thing I tried was to run 3.11.1 under Xvfb. CPU load dropped to
under 5%, which means that there is a serious problem with how fldigi
interfaces with the X-server.
I don't get this problem on the desktop, which has a much faster CPU
(the CPU of the server is 2 GHz).
It looks like the problem occurs especially when fldigi runs under a
vnc session.
Anyway, it runs fine now under Xvfb.
To start fldigi under Xvfb do the following in a terminal (use screen
as your display manager):
Xvfb -ac :99
fldigi -display :99 &
fldigi is now running headless and takes only 5% CPU, leading to a
much better
decoding of PSK250

I'm seeing 10% max cpu useage here.
But I'm only running a client and no VNC session.
3.0Ghz with 1 Gig of ram.
