Xqt Soft Float
« on: June 09, 2005, 05:12:31 pm »
XQT has always struck me as sluggish in sharprom.
In OZ, is XQT recompiled with softfloat? Can it be? Should it be?
Wouldn't this give opie XQT better performance? Allow the use of soft float enabled gpe apps? better use of pocketworkstation,if wanted, etc?

I am betting that this has been thought of before, But I couldn't find it in a search, and so, I thought it might be worth a discussion.

The whole OpenZaurus feed is compiled with soft-float.

I know opie is gernerally snappier than sharprom.. has anyone compared xqt/opie with xqt/sharp... running pocketworkstation, a gpe and a pdax app? I would assume opie/xqt would turn out better, but it would be interesting to see.

I had thought maybe compat libs were used, though 3.5.3 seemed to be getting further away from using compat

hmm, performance is allways relative to the kind of measurement you use. ..

Softfloat is one thing that can make some applications faster, but then running pocket workstation app in a chrooted environement you will not use   softfloat.

Softfloat will make an application significantly faster if a lot of floating point operations are used.

For display, hardware graphics acceleration is another thing to take into account...I don't know if, on the 6000, there is a distribution that offers  this besides the sharp rom. (pdaxrom does not) so X/qt might be "faster" on sharp rom than on OZ despite softfloat.

I think as OZ is able to run opie and gpe (X), not at the same time thus you don't have the 2 environements competing for resources,  might be the best way to have the best of the 2 world.
