> vqsort authors found that at 1e8 elements a hybrid of ips4o (samplesort, think many-way partition) beats pure vqsort. Whoa, important caveat there: we did the hybrid with ips4o as an easy way of getting multicore support. We also mention pure scalar ips4o is slower than vqsort until it can use _19 threads_ (vs one for vqsort). It is the combination of multiple threads (to compensate for the much slower scalar code) and bandwidth friendliness that makes this hybrid useful.
