It depends.  If the graphics card is very fast, the limiting factor 
may be the unpacker/crserver, or it may be the network.

One easy thing to do is run 'top' on the crserver host while 
Chromium's running to see how busy the CPU is.

I don't think function calls are too big of deal there; we're doing 
just about as good as we can.  On Linux (and other platforms) we're 
using assembly code for dispatching GL functions (see 
opengl_stub/Linux_i386_exports.s).  And if a SPU doesn't 
implement/override a particular GL function there's no undue cost.

With all the different possible Chromium configs, it's hard to be 
specific.

Do you have a certain configuration in mind?
