 Hi there and welcome to WordPress Trac!

 `admin-ajax.php` isn't a single file with a fixed file size. It's a way
 for WordPress core, plugins, and themes to perform Ajax requests to
 perform certain actions. Since you haven't logged in to the admin and
 WordPress itself doesn't do any Ajax requests on the front end, it sounds
 like your theme or one of your plugins is responsible for this.

 To find out which one exactly is responsible, try opening the developer
 tools in your browser by pressing F12 when browsing your website and look
 for `admin-ajax.php` in the Network tab of these developer tools. Look for
 "action" in the request headers. There you can see which Ajax request is
 actually performed. Also check the response body to see why 32KB of data
 is sent back.

 Try to disable any plugins and use a default theme like Twenty Seventeen
 to see whether the issues persist.

 To further help you analyse the problem, please open a new thread in the
 support forums at https://wordpress.org/support/. Ideally you use a plugin
 like https://wordpress.org/plugins/health-check/ to provide as much
 information as possible in the support request.

 As I mentioned in the beginning, WordPress itself doesn't do any Ajax
 requests in the front end, so this is not a bug in WordPress. Also, there
 haven't been any changes to `admin-ajax.php` related matters recently, as
 far as I can tell.

 Since WordPress Trac is used for tracking bugs and enhancements in
 WordPress core, this request doesn't really fit into this. That's why the
 forums are a much better place.
