Dear Gordon,

With such large data set, and presumably many regressors, quantile regression
will always be slow; bootstrapping  makes it even slower. So, you just have to wait 
a bit longer... 

Alternatively, instead of bsqreg you can use qreg2 (available from ssc). It won't do
the simultaneous quantile estimator but there may be a way to avoid it. Feel free 
to contact me directly if you want to discuss this further.

With best regards,

Joao
