If I set up a cron job to run every 15 minutes to update stats for an online game, do you think this would use much bandwidth or cause problems on the server?
Well, i think that is may put a load on your server/ram depending on how big a database of stats there is and such. And how powerful or a server it is.
As running a Cron every 15min for something big may put great strain on the server.
mabey run the cron once and see how the server holds up to it. then decied from there if it is capable of doing it every 15 minutes.
If its only taking 2 seconds i think it would be fine. i would check on your server to make sure it is doing fine though for the first few hours of running it every 15mintures. just to make sure its not gonna make your server crash.
Oh, this is not on your own server. I though it was. Your on a shared hosting account? Yea i think its fine to do then, If you are with a decent hosting comapny they would contact you first and ask you to stop the cron before canceling your account.
Ok, so that means that there servers are in a good datacenter and on a good server. That doesnt mean that the people running it are nice. How has the support been? Has it been good? If so i dont think you need to worry to much.
Mabey you should open a support ticket asking them about running a cron and what they would do.
