Why robust loess takes so much of time

%%loess
acc=dlmread('acc8.txt');
t=dlmread('time.txt');
[xx,ind] = sort(acc);
yy = smooth(t,acc,0.5,'rloess');
plot(t,yy(ind))

[John D'Errico]

Some computations on large data sets will be computationally intensive. The solution is simple. Use smaller datasets, OR find a different algorithm.
