The bottleneck is how many the operating system and hardware can handle.
:)IIS is quirky if it simply limits the number of connections arbitrarily.
POF users spend, on average, about 10 minutes creating their profile, but those who spend about 20 minutes are twice as likely to leave the site in a relationship.
And POF users who add detail and photos to their profile are four times more likely to meet someone on the site than users who have minimal detail and no pictures.
The discussion in the comments is as interesting as the article.
My guess is Markus doesn't want to rewrite his software to work across a scale out cluster so even if it's more expensive scale up works better for his needs.
all u need is a reliable site and no interference and the lottery word of mouth ie someone won a million here and there "IIS arbitrarily limits the total connections to 64,000 so a load balancer was added to handle the large number of simultaneous connections."I'm glad that was cleared up.
When the author of plentyoffish made the original post about his setup, there was a lot of vagueness.
Update 5: Plenty Of Fish Update - 6 Billion Pageviews And 32 Billion Images A Month Update 4: Jeff Atwood costs out Markus' scale up approach against a scale out approach and finds scale up wanting.It probably enjoys the benefit of kernel-space IO which is much faster than user-space. Maybe you can use different table types, caching policies, and other read optimizations as well. NAT only supports 64,000 connections per Source IP address.It's hard to believe that no caching is being used at all; but it's not impossible. Its nothing to do with IIS its TCP/IP related. SI supports a maximum of 64,000 simultaneous connections on each source IP address.Update 3: POF now has 200 million images and serves 10,000 images served per second.They'll be moving to a 250,000 IOPS Ram San to handle the load.
