Considering you're Linux you could also try xvidcap (which has GUI)

But to be honest I doubt they would make huge differences from
Instabul or recordmydesktop.
I often find the bottle neck on most machines is not the video/audio
encoding but how fast the data is being captured. For that you could try
capturing at a smaller resolution or slower frame rate. I also notice a
better display card does give a better performance, possibly related the
xshm implementation of the driver and other display card specifics like
memory bandwidth.
And also depending on your machine and disk, you can try
capture+encode on the fly versus capture-into-frames (jpg/png/xwd) then
encode later. Though my personal experience is on slower processor they
yield pretty much the same performance, while on a faster processor (say
>2GHz) it is faster to capture+encode on the fly as there is less disk
io.
Another option which I have used at my day job with excellent results is to
get a scan converter that converts your vga signal to NTSC (or PAL) video.
Now pipe that video output into a video capture box that is plugged into a
second computer. It's more expensive than an open source software package,
but the results are full smooth frame rates since you don't have two
applications competing for the same video/memory/disk/cpu resources.
