Alternatively, you could run cron jobs in Sid Desktop by first installing the cron daemon (sudo dnf -y install cronie) and then creating a crontab (crontab -e), but this will cease to operate when her Sid job is terminated.

Will requesting more resources slow my job's performance?
No. A CPU is a CPU and RAM is RAM. Sid does not allocate cheaper, worse-performing hardware based on request size. Additionally, running multiple jobs will not degrade performance. Sid users can run up to eleven jobs without any performance degradation (as each is allocated dedicated resources from AWS).
