Quantreg `summary.rq` takes too long to give results

Question

I have a data set (joined) of 730,099 observations and 16 variables, to which I applied a quantile regression model using the following code:

library(quantreg)

taus <- c(0.1, 0.25, 0.5, 0.75, 0.9)

res <- rq(Deprivation~Age+Education+Gender+Size+Employed+Children+Condition+Milieu+DwellingSize+Ownership+
            DwellingType+Region, tau = taus, data=joined, method = "fn")

However, when I try to create the summary using the summary function, it takes a very long time to give results (this is my second day waiting for results). I tried different options; se = "nid", se = "iid", se = "boot", se = "conquer", and bsmethod = "BLB", but they either don't work, or keep running indefinitely. Any suggestions as to how to make summary run faster would be much appreciated. Thank you in advance.
