I currently run on a VPS that is running the latest version of Ubuntu, PHP 5.5.9, and WP 4.0, and have been running my plugin upgrades through
libssh2 via a configuration in
wp-config.php ever since I started working on this VPS, as WordPress is unable to open a connection automatically.
However, within the past week or so, I've noticed plugin installs and WordPress upgrades have become increasingly slow, with the browser hanging for almost 1-2 minutes before confirming that my plugin is installed. (Jetpack takes an extremely long time to update, as an example.) One side effect that I've noticed is that PHP often exits before the
.maintenance file is removed. Problematic, as I then have to go and remove it myself by connecting to the server.
Is there a way I can speed things up and get PHP to run faster?
