Crontab frequency

[brettbaker]

Hi When Installing your app I get to the end and it want me to add the following to my crontab file

"* * * * * /opt/alt/php54/usr/bin/php -f /var/www/vhosts/xxx/httpdocs/crm/cron.php > /dev/null 2>&1"

Firstly why does this need to run every minute of every day? Is this not excessive on my web server?

if not what would be your suggested frequency And could you pls clarify what this is doing for the system each time it runs?

It's recommended frequency to run crontab. No, it's not excessive for the server.
Every time when crontab runs, script executes Scheduled Jobs. Their list you can find in Administration -> Scheduled Jobs.
Also, if you want you can set every 5 minutes as well. So, in this case if you have active "check inbound emails" job, it will have some delay in receiving incoming email.
