Back in March I blogged about replacing the standard ClasicPress cron job with a system cron running on a schedule. The reason I did this was to improve the efficiency of my sites by having cron called on a schedule rather than every time a page was loaded.
However, I’ve recently been adding new functionality to my To Twitter plugin and found that scheduled tweets containing images were not working. I did some exploring and discovered that the problem was that cron jobs timeout after 30 seconds and processing one large, or several smaller, image would exceed this timeout.
I then found that an alternative method of calling cron seemed to run much faster and I was no longer having problems with the cron job timing out. This alternative method uses wget:
wget -q -O - https://{your domain}/wp-cron.php?doing_wp_cron >/dev/null 2>&1
The highlighted section should be replaced with your domain.
What should we write about next?
