How do I know how long I need for a cron job to execute? I was with mediatemple as a host and their cron job didn't work properly because of their cron job limitations. So is there a way to find out how long it will take? It imports roughly 6000 products.
You may sign up a free account first, add the cron job, and then test it (After you add the cron job, you will find the test link). Then check out how long it takes to run. If it takes longer than 5 seconds, you can upgrade your plan to paid plan.
If you're handling thousands of products, an advanced plan should be more reliable to avoid cron timeout.
