I've been working for HFT firms since I moved to NYC over a decade ago. The article looks like a good summation HugePage benefits (I'm a sysadmin, not a programmer so I understand it on a topical level only).

What I do find fascinating is that HRT is actively blogging about this stuff. Ten years ago, everyone in the biz was super secretive and never made any public announcement about what we did - even stuff that I would take from HPE and RHEL low latency manuals (which were public knowledge). You never said anything publicly because protecting the "secret ingredients" of the trading system was paramount and any disclosure was one step towards breaking that barrier.

Now, I'm seeing HFT companies post articles like this and I'm thinking it has to be for recruiting. Why else would they do it?.

Anyway, as a side note, if you liked this article, you'd also probably like this:

It was one of my favorite reads because it was written by someone going thru the journey of low latency exploration - before everything was taken over by FPGAs.
