This is a fri through mon inclusive. The sat was actually the day of startup school.
Orange = requests/sec; black = memory used; red = % time spent in gc; blue = median msec to serve an item page; green = median msec to serve the frontpage. The last two are unnaturally spiky because I use a very narrow window (because we use the same data to to drive our Leftronic screen at YC). So the blue spikes don't represent anything that would have been observable to users.
The slowly rising gc percentage (red) is a sign of memory leaks. They used to be a lot worse before Rtm finally tracked down the main culprit this summer.
We're now getting a bit over 900k page views per day.
- pama 16y agoHow much did HN grow in the last year or so?
- pg 16y agoA bit under 2x.
- derwiki 16y agoHow many unique visitors?
- pg 16y agoWe now get around 75k uniques on a weekday.
- dzlobin 16y agohttp://news.ycombinator.com/item?id=1152389 http://news.ycombinator.com/item?id=1152389 Looks like we're getting close to doubling in uniques, compared to 45K 8 months ago.
- pygy_ 16y agoThis isn't very surprising. See [1]. Also of interest, HN vs Clojure vs Common Lisp [2]. 1. http://www.google.com/trends?q=hacker+news&ctab=0&geo=all&date=all&sort=0 http://www.google.com/trends?q=hacker+news&ctab=0&ge... 2. http://www.google.com/trends?q=common+lisp%2C+hacker+news%2C+clojure&ctab=0&geo=all&date=all&sort=0 http://www.google.com/trends?q=common+lisp%2C+hacker+news%2C...
- skbohra123 16y agoany plans for monetizing ?
- siculars 16y agoHN is sort of a loss leader for ycombinator. Free advertising for all the YC comings and goings. HN is the leader in mindshare amongst those interested in startups, startup technology and startup culture and (obviously) startup news.
- pclark 16y agoalso job postings
- fharper1961 16y agoHN is already monetized, albeit indirectly, through discrete and relevant references to YC products. For example the reference to Leftronic in this post.
- BrandonM 16y agoI'm not usually one to correct grammar, but discrete and discreet mean very different things.
- fharper1961 16y agoOops, thanks for pointing that one out!
- smanek 16y agoIt's already monetizing, by getting YC amazing deal flow
- seldo 16y agoThe slowly rising gc percentage (red) is a sign of memory leaks. So do you reboot regularly, or what?
- pg 16y agoI'd have to restart the server once a week or so if I didn't end up doing it more often anyway because of releases.
- roadnottaken 16y agoDoes HN run on a single machine??
- charlief 16y agoFrom http://news.ycombinator.com/item?id=1721105 http://news.ycombinator.com/item?id=1721105 "Conservative, I know, but we're serving 800k pages a day off one server"
- ericflo 16y agoI don't see yellow, but I do see an orange. Was that a typo, or is my monitor seriously mis-calibrated?
- pg 16y agoOops, fixed. For some reason I think of it as yellow, but it is in fact ff7700.
- fierarul 16y agoGoogle Charts also allows you to set a legend. It really should be part of the graph.
- pg 16y agoThese graphs are just to tell me if anything is going wrong with the server. They're not really intended for anyone else to see. E.g. this is the graph at this moment: http://chart.apis.google.com/chart?cht=ls&chco=ff7700,000000,ff0000,008800,444499&chs=155x300&chd=t:51,50,53,58,61,68,73,80,86,83,84,91,89,88,93,91,92,91,86,85,82,74,76,77,73,72,68,66,67,63,58,57|17,21,19,23,22,24,23,27,29,24,26,23,26,30,28,28,28,26,27,28,27,28,28,26,27,29,26,30,28,24,25,27|21,23,24,25,25,25,26,26,26,27,27,27,27,27,27,27,27,27,28,28,28,28,29,29,29,29,29,30,30,30,30,30|16,14,1,14,14,14,15,0,15,1,0,16,45,16,51,16,16,16,64,26,27,15,18,16,17,16,17,15,16,20,16,24|5,5,3,5,4,7,12,3,23,3,441,705,68,3,6,4,6,6,14,3,2,4,5,4,5,11,5,3,21,6,5,4 http://chart.apis.google.com/chart?cht=ls&chco=ff7700,00...
- aralib 16y agoThough fierarul's comment leads to a natural question. The original comment explaining the graph is really necessary for the link to make sense. Explaining the graph in a comment seems to break the (apparent) convention of submissions being self-contained. I thought the reason for disallowing both a URL and text in a submission was to avoid this. Though, if a submission that requires a comment is acceptable, why not allow submitting both a URL and text?

- pg 16y agoThere is a difference. A comment is voted up at the discretion of the users, while text associated with the url would be displayed at the top no matter what. Which would mean the first person who submitted a link could essentially make their comment upon it always be the top one, and define the discussion.

- dabent 16y agoI really liked the flat-screen monitor up in the YC offices to track the site. I want one for my site. It seemed the site wasn't getting much traffic, but then I realized most of the users were in the room at the time.
- catshirt 16y agoWhat was the original memory leak?
- pg 16y agoIt was in something I added quickly to fix a hole someone discovered. I made the mistake of memoizing the function that generated authentication keys for vote links.
