Memory Leak upon creating a new post. Dial-up speeds to create a post.

    You have an AJAX, Gravator.com-related memory leak on your site. It’s causing perpetual performance problems. It happens when you click the “New Post” button on one’s blog. When I open Chrome Dev Tools and click on the Network tab, I notice that random gravatar images keep loading on a second-to-second basis to my browser, even though I have stopped typing and interacting with the browser. It is causing my typing to lag to a turtling pace. These images are random, too — of stock photos, logos, etc. that I don’t recognize. Please fix this. I’m ready to just create my own blogging CMS instead.

    The blog I need help with is: (visible only to logged in users)

    I think these photos that keep getting loaded into my browser are real-time uploads from other users of gravatar.com… in which case, you have thread-unsafe code somewhere.

    Good luck fixing it.

    Hi,

    I’m investigating this issue for you. My initial investigation indicates that these gravatars may be of users being featured on the page that you’re on. Which page were you on when capturing this response?

    For example, the http://wordpress.com/#!/read/fresh/ page will return the gravatars of everyone who has been featured on the page, and if you have scrolled down, it will return a new set of featured sites.

    Is that consistent with what you’re seeing?

    In addition to WordPress.com, you may want to check out WordPress.org, which is the software that is the core behind WordPress.com and you can host on your own server. If would save a lot of time from building something from scratch!

    Please let me know if you have any other questions or need anything else. Thanks!
