I think it would be interesting to bump it up in 2018.
What is the fastest aligners out there? I have heard (I think Heng Li wrote it somewhere) that with changes in computer architecture, hash-based aligners are coming to be more and more interesting, compared to FM-index based. I am about to try our SNAP, which promises up to 20x increase compared to bowtie2 and bwa.
Like Istvan rightly pointed out, aligner has to be fast for your application. But sometimes speed could be a limiting factor - e.g. when you are teaching a class and want to show something pretty quickly, and not wait for 30 minutes.
