File forwarding capacity is the maximum rate per minute
at which each Palo Alto Networks firewall model can submit files
to the WildFire cloud or a WildFire appliance for analysis. If the
firewall reaches the per-minute limit, it queues any remaining samples.
The Reserved Drive Space column in the following table lists
the amount of drive space on the firewall that is reserved for queuing
files. If the firewall reaches the drive space limit, it cancels
forwarding of new files to WildFire until more space in the queue
The speed at which the firewall can forward files to WildFire
also depends on the bandwidth of the upload link to the WildFire systems.
