# Scan Schedule

 * I know that you can only schedule a scan with the premium version of the plugin
   but how does Wordfence decide when to scan? It seems to do it in the middle of
   the work day all the time and if it’s on a lot of sites on one server it can 
   cripple access. Why wouldn’t it automatically pick an after hours scan time? 
   Thanks.

 * Hey [@zorlac](https://wordpress.org/support/users/zorlac/),
 * The schedule is triggered by a cron job that’s initiated when you install Wordfence.
   It doesn’t have a way to know your optimal hours to scan. If you do seem to be
   running into resource issues you might try reinstalling to try and adjust the
   scan timing.
 * With that said, it really shouldn’t cripple the server if you have ample resources.
   If you do run into resource issues, please let us know and we can take a closer
   look.
 * Thanks,

 * I have just over 100 websites with the plugin on 1 server and it appeared that
   the majority of them were scanning at the same time. Unfortunately the time was
   a late morning/just before lunch scanning time.
