Numerous admin-ajax.php processes slow down server

    I’m running into a big problem upon updating both my wordpress installation (3.9.1) and this plugin (1.0.35). It appears it is causing multiple instances of the admin-ajax.php process to run on my server (the issue is more noticeable during peak hours) and this processes end up clogging the server and slowing everything down. I have narrowed it down to this plugin as it seems that as soon as I disable it, the processes are killed and site performance goes back to normal.

    Does anyone have an insight or a solution to this?

    Lively hits admin-ajax.php in a couple places:
    – once on every page load to grab info (this is to avoid caching)
    – when someone starts a chat, it is hit every 3 seconds to see if there are new messages
    – when someone deletes their conversation history
    – when a message is sent

    My guess is that the bottleneck is polling for new messages. For a simple test, you can just find every place of “3000” in the code and change it to “6000” and see if that makes a difference (changes polling time from 3 seconds to 6 seconds). This is on line 81 and line 423 of chatbox/js/chatbox.js.

    When you say peak hours, how many chats would be happening at that time?
    Are you using Triggers or Surveys?

    Resolved.

    Hi, I am also having this issue. Basically it’s slowing page load time by around 8 secs when using Pingdom to test the speed. Note that the site does not have any visitors yet.

    8 secs is obviously an unacceptable page loading time. What can I do?

    Thanks, Simon

    Were releasing a new version in the coming week or two that should fix the issue. Thanks!

    Yes please, the sooner the better.

    Hi, could you let me know when you anticipate this update being ready?
