If your Prisma® Access deployment uses a large number of sessions, and you would like to delete those sessions quickly, you can enable fast session delete, which allows Prisma Access to reuse TCP port numbers before the TCP TIME_WAIT period expires. This reuse of the TCP port numbers can be useful if your deployment has a large number of SSL decrypted sessions that may be short-lived. You can choose to enable this functionality for Prisma Access Remote Networks, Service Connections, and Mobile Users—GlobalProtect®; for Mobile Users—Explicit Proxy deployments, this functionality is enabled by default and you cannot disable it.
