Intrusion Prevention causing slow internet speeds

Since upgrading the firmware to the latest version 9.312-8 my internet performance has fallen massively. I have a Gbit connection to the internet and with Intrusion prevention turned on, I get anything from 10mbit to 100mbit depending on number of users. If IP is turned off my internet download speed jumps up to 650-800 Mbit/s.

Can anyone shed some light on what is wrong?

Thanks
