He used to post on webmasterworld as he was developing the site. Some interesting stuff. And it's on IIS which blew my mind. webmasterworld.com/profilev4.cgi?action=view&member=markus007

I could be mistaken but I am pretty sure Stack Overflow also runs on IIS.

Does anyone know the technology stack used for front and backend by POF?

It used to be based on IIS and ASP.NET (one of the biggest Microsoft success stories on those technologies). Edit: from http://en.wikipedia.org/wiki/PlentyofFish they used ASP.NET 2.0 and Microsoft SQL Server 2005 in 2007.

Thanks. I just checked their pages are .aspx which is Microsoft ASP.Net.

Another point in function over design, just like Craigslist.

Not really. Contrast the cluttered mess that is PoF to OkCupid, which has decent usability and reasonable information architecture. OkC's design is also better at extracting the right information from more users more consistently, meaning the resulting corpus of data is more complete. Which makes for a better product, since it's easier to find the sort of people you'd be into. PoF is successful in spite of its questi…

too bad both sites use the old stereotypical pictures+profiles approach to dating unlike flirtrs which actually makes you go meet people (cause you know, if you are trying to meet people it helps to go meet them)

> And it's on IIS which blew my mind. I think that says a lot more about you than about IIS. It's mature software, why wouldn't it perform on par with other mature webservers?

It isn't to say a lot of people thought it was impossible, but it is just very unheard of. Anecdotally, most of the people I know hadn't heard of it either. Slashdot, Facebook, Wikipedia, etc were the very large sites talking about what they used over the years and it was all about the open source stuff like Apache, PHP, etc. Then I found out, on HN, that POF used IIS and it was mind blowing. You would think even Mic…

Hotmail, for one, moved to IIS from its bought-in FreeBSD roots many years ago.

Sounds like a worse is better case study.

Or an example of the network effect overriding other condsiderations. PoF got big before OKC did, so that's where the people are.

Even with that factor though, I found PoF borderline unusable after a little experimentation and stopped using them in favour of OKC. I can't believe I'm the only one like that, or that there aren't some who simply dropped off PoF into nothing.

If that crappy site can extract value at such a high level, I'm sure a few reasonably small tweaks could extract significantly more.

Here's another mind-blower: enom runs the largest IIS server farm in the world (at least they did up to a few years ago)

Can't find a direct link but I remember that little factoid because it surprised me.

I don't mean customer servers sold as services, this was before then, it's their own server network.

If you are thinking of modern IIS (v7+) it is a complete rewrite so technically not "mature" software at all.

IIS 5.x was horrible which is what most people who have been around think about when we hear "IIS".

So around 2.3k HPS monthly average. Assuming an average peak is 10 times that, 23k HPS seems a little little high but doable for a handful of servers (after load balancing and caching come into play). One note says "everything is dynamic, nothing is static" which sounds weird if they're using Akamai for anything but images. Images are claimed to be served at 100K HPS, which would be difficult for a handful of servers…

You can do a lot more than asset caching with Akamai; they have stuff from "edge-side includes" all the way up to your own J2EE at the edge.
