    I would evaluate alternatives to EC2 before committing. For example, I have found that Linode performs significantly better for my purposes.

  2. handsoffsam added a post in a topic: Very Slow posting in topics with Followers   

    It looks like this has been covered, but just to relay my experience (pun intended...), if you're using an external mail service, it is a good idea to use a local spooler (ie postfix) that is then configured to relay through whatever service you're using. Otherwise you can definitely see performance issues when posts are made to topics with lots of followers.

    +1 on the nginx+php-fpm combination. Very flexible. Separation of duties is almost always a good thing.

    FWIW, I use Amazon SES, but I found that having a local postfix instance queue the mail improved posting performance dramatically. My mail flow goes: forum->postfix->amazon->[etcetc].
     
    As a side benefit, I can see nice mail logs now. And if there is a problem with Amazon, the mail is nicely queued up.

    Nice writeup. That's about all I do to secure my systems, as well. I recently started running denyhosts and it seems to work well.
     
    One other comment: there's no reason to make the username obvious, either. I use KeePass' password generator to generate my login names when I really, really care. Pretty much nobody is going to be trying to log in as "gT1JKouF", for example.

    Varnish isn't a real good fit for IPB, given that just about every page is unique for each visitor. It is much more interesting in situations where you're serving the same resources for many people.

    Without seeing your nginx configuration, it is hard to know for sure, but I would start by suggesting that you look at your gzip_types directive.

  8. handsoffsam added a post in a topic: Thoughts on Content Delivery Networks (CDN), Google PageSpeed   

    I have played with Amazon's CloudFront and PageSpeed. Both are "okay", but in my opinion not necessary.
     
    My site, at least, utilizes the browser cache very well. If you're using the browser cache, then the CDN is irrelevant except for the first, uncached hit. In my opinion, it added more complexity that wasn't really gaining me anything.
     
    PageSpeed is similar: more complexity that wasn't really gaining me much. It's a neat concept and there are probably sites where it would genuinely be useful, but my IPB forum isn't one of them. You should try it and determine that for yourself, of course.

    Hello,
     
    I'm not sure if this is the right place for this, but I have a strange issue with Safari. Basically, when I browse some threads on my forum, I get the "With x checked posts" popup. I am not using a moderator account. It doesn't happen consistently, but it happens a lot. For example, this link triggers the behavior maybe 50% of the time:

    I don't see this with Chrome or Firefox.
     
    It's not a showstopper or anything, but it is pretty darn annoying!
     
    Thanks,

    Yes, the sheer number of requests that you are making guarantees the page load time to be awful. Here's a WebPagetest run of it: http://www.webpagetest.org/result/131213_2K_FTR/
     
    As Grumpy noted, the worst part is the number of third party resources. And many of those are not cached at the browser. Yikes. You should _NOT_ have 58 requests on the "repeat view".

    My favorite tool for this sort of testing is WebPagetest: http://www.webpagetest.org/result/131213_9B_475/
     
    Something seems wacky, I've had the initial load under 1s in the past. Not that the result there is terrible.

    Amazon SES is another option:  http://aws.amazon.com/ses/

    Start by using strong passwords. Use a tool such as KeePass to generate and store them.

    The only way to know is to measure. IMHO, one of the better tools for measuring is Web Page Test:  http://www.webpagetest.org/

    Other than making things a little bit more complex, correct, you generally are not going to hurt anything by using a CDN. I really recommend that you understand caching as it relates to HTTP protocol before introducing a CDN to the picture. As I tried to mention above, there are several layers of caches that exist. The best and fastest cache is the browser cache, and in general, IPB does a great job of utilizing it. This makes a CDN less likely to be useful.
