I am removing it also. All sites are almost unresponsive. After deactivated Jetpack everything back to normal

I am also searching for same. I figured that logged in user can call: WP_Optimize_Page_Cache_Preloader::instance()->run('manual'); But from cronjob script is not executed as it need.

It also works with bash script, but it’s not good solution for me:

#!/usr/bin/env bash

site="https://www.web.com/"
login_address="$site/wp-login.php"
log="user"
pwd="pass"
cookies="/tmp/cookies.txt"
agent="Mozilla/5.0"

# authenticate and save cookies
wget \
    --user-agent="$agent" \
    --save-cookies $cookies \
    --keep-session-cookies \
    --delete-after \
    --post-data="log=$log&pwd=$pwd&testcookie=1" \
    "$login_address"

# access home page with authenticated cookies
wget \
    --user-agent="$agent" \
    --load-cookies $cookies \
    "www.web.com/test.php"
