cron jobs. What are the mandatory ones?

[Fabrizio Lazzaretti]

Hi All !
i noticed some cron job is very cpu expensive because of some complex sql query.
in particular:

* * * * * www-data /usr/share/nginx/html/cake2/rd_cake/Console/cake -app /usr/share/nginx/html/cake2/rd_cake Accounting >> /dev/null 2>&1
* 
*/15 * * * * www-data /usr/share/nginx/html/cake2/rd_cake/Console/cake -app /usr/share/nginx/html/cake2/rd_cake Voucher >> /dev/null 2>&1

#Every two minutes; you ma want to increase it on bigger deployments
*/2 * * * * www-data /usr/share/nginx/html/cake2/rd_cake/Console/cake -app /usr/share/nginx/html/cake2/rd_cake Removeduplicates >> /dev/null 2>&1

in terms of radius only functions, which of these are mandatory ?

Thank you
Best Regards
