Hey all. It's been awhile since I last posted - sorry about that. Just want to give a status update...

Perhaps you've been noticing some intermittent slowness when using Quizlet. I've been noticing it too - 30 second load times for each page are no fun. Sometimes it's nice and snappy, sometimes it's agonizingly slow. I believe this is an issue with Quizlet's host, and not any "growing pains" within Quizlet. Their site is slow at the same times that Quizlet is slow.

Apart from that, I've been making changes here and there to improve performance and fix bugs. There was a fiasco with smileys a few days ago, but they're back up and usable again. There's nothing epic to say here in this post...Sorry :)

[UPDATE May 29th, 2007] I just twiddled with some settings a bit and improved some mysql settings - these slowness problems should be fixed. You should notice some extra snap in the page loads now. I especially helped out the Quizmarklet, which is AT LEAST 15x faster now. It's now very enjoyable to use. Yay.

    One problem that came up is that your private messages don't delete right away. You have to go to another page then go back to your private messages for the message to be deleted.

    I'd suggest you to change host and go for WebNX. Search "WebNX" on webhostingtalk.com and check out their offers. I have been with them for two years already and never experienced any slow time or network problems.

    yeah i can tell when i reply to messages it takes 34 minutes!!! ok, im used to slow, but 34 minutes???? that's quite a lot

  10. sam

    I can not spot the difference, its not slow on my computer, or maybe its just me but whatever.

  11. Katie

    I have something to tell you...
    when i am "learning" something on Quizlet, if i mistype and write
    Wyomingg instead of Wyoming, it is marked wrong. I think that you should be able o go back, since on your browser it says that the page has expired.

    Thank you!

  12. alana

    omg i totally agree katie! i have to keep track of how many i have wrong and right on my own.i say that when we make sets, we can put variations of the answer. just an idea.

  13. Katie

    Just curious -- what exactly fixed the problem? Inefficient queries? Or did you enable query caching or something like that?

    Love Quizlet :)

  18. Andrew

    Michael, a couple of things:

    First, my hosting company had a few problems with some hacking activity, which they've now contained.

    Second, last night I boosted some of the query caching and key buffer size vars in my mysql configuration. And I added a couple of extra indices on key tables - one index especially helped the quizmarklet response time go from about 800ms to 140ms. That's good :)

    geez my computer is just as slow as my brother's

  20. genova

  21. Michael


    Ah, yes, indices help a LOT in cutting down common SQL queries. Thanks for the info!

    I just registered on quizlet.com.
    I'm planning to go looking round somewhat and make contact with interesting people and learn a few alternate viewpoints.

    Hopefully this message is not in the wrong category. I'm sorry if it does.
