AIX HMC IBM

IBM HMC client performance

The HMC java client’s performance is painful, especially if there is much latency on your connection. It also requires Windows. IBM had published a workaround for the performance issue using VNC (which should also work for other non-windows OS’s)

Which is OK, but if you have X11 available I prefer this:
Connect to an lpar
run
wsm -host HMC_NAME

This will open an X11 based HMC client window.

You can also just run
wsm
and add hosts from the client
