Vim on an embedded system

Hi,

I am running vim on a Beaglebone Black with Gentoo Linux
(512MB DD3, 1GHZ ARM Cortex A8 CPU). I am connected to the
Beaglebone black via SSH, which is -- for example while
using shell commands -- fast.

Currently I am mainly editing Lua code. Unfortunately this
seems to be damn slow...partly I am waiting for the characters
to appear on the screen or that a movement of the cursor finally
happens.

I had compiled vim natively on the Beaglebone Black with all
features I am using on my PC.

I am using vim exclusively -- NOT gvim -- from the console. I am
currently not using X11 on the Beaglebone Black for vim editing
sessions.

vim --version shows:

Is there anything I can compile differently to give me better
performance by mainly preserve the features?
(Or -- and not meant total seriously -- I dont want to strip off features
until I have a lighning fast ed... :)

The gcc compiles hardfloat using the mpu.

Thank you very much in advance for any speed improvement hint! :)

Best regards,
mcc
