High CPU usage

    Several months ago after installing MailPoet 3 I have experienced high CPU usage. Problem was solved with installing MailPoet 2.

    Yesterday I had again high CPU usage problems and the problem was in MP2 cron job.

    I have installed MailPoet 3 and manually configured cron job to once in 2 hours in the cPanel since I’m not sending mails very often.

    But I have just experienced CPU problems again. As soon I have disabled MP3 plugin the problem was solved.

    How to fix this?
    What is optimal frequency for the cron job?

    Thank you.

    EDIT:
    I’m also on SIteground. Is it better to manually setup cron job or use “Visitors…”? My site have aroud 1000 unique visits per day.

    Can support give me an advice how to solve CPU issue. Becasue my only solution was to unsitall the plugin.

    Hey guys,

    We now offer the option to set up a server-side cron (Linux cron), which may help you with the high CPU usage issue.

    Like Pedro mentioned, SiteGround has a documentation to guide you: https://www.siteground.com/tutorials/cpanel/cron-jobs/#Adding_a_cron_job

    You should go to MailPoet > Settings > Advanced and select the option “Server side cron (Linux cron)” as your Newsletter task scheduler (cron). Then just follow the on screen instructions.

    We hope it helps!

    Thank you for the reply.

    I have done that as soon as I have activated the plugin.
    I used path from the settings and created a cron job in the cPanel. Frequency was set to once in 2 hours, like I have explained in my post.

    I had to deactivate plugin last night. After 24h I have reactivated it and processor went up. As soon I have deactivated it CPU went to normal:

    So what is the solution?
    I will migrate from Siteground soon. Are you experiencing the same issues on other hostings? I want to migrate to cloudey.net. Will I experience same CPU abuse with them also?

    Is solution to downgrate to MP2?

    Thank you.

    @pedro-magnifico
    What path did you use? I have copied the path that I get in the settings but it seems it is not working.

    Used wrong path in cron job.

    Now it is OK, thanks.

    @amedic, you have sorted your issue, correct?

    @mailpoet, I thought that I have, but after reactivating the plugin I had spikes in CPU and RAM usage. They lasts for about 5 minutes and after it everything is back to normal.

    I had to deactivate the plugin.

    Do you have problems only with Siteground?
