Couple of questions about Linux's ability to handle tasks.
I've created a simple cron job (2KB) in Perl that reads a directory on my server every 1 minute, sorts, and deletes the old files. Does this sort of cronjob, one that executes every minute, put a lot of strain on the server? It's a small cronjob, so my assumption is it's no sweat to the server.
If I send a batch of e-mails (no more than 20) at one time using qmail, why does it take some e-mails longer than others to arrive at their destination? Some e-mails arrive in a few minutes -- others can take several hours. Again, using Perl to send the e-mails. Is this most likely a qmail issue or an issue related to the user's inbox?
Thanks in advance!
