Are you comparing apples to apples here?

What is the bandwidth of your resampler?

>From the comments in the code it seems that your resampler is not an 
abritrary resampler like mine but an 2 times upsampler. Its not really
a fair comparison to compare a general time varying resampler like
mine to a 2 times upsampler.
