IPS\IDS Horrible Performance

[ElectroStaticD]

Hi, I have a 1Gig bi directional wan and When I enable IPS\IDS my throughoutput drops from 980Mbps down to like 200 bidirectional.  I've gone through all of the tuning threads and nothing helped.  Any ideas why the latest version of OpnSense would do this or how to fix?  I was previously using PFSense with the same hardware + Snort and no issues at all.  This is the hardware I'm using.  Anyone have any ideas?

From your link, do you have 4GB or 8GB? The latter is recommended for use with Suricata or Snort. A J3160 is not high-powered though it is ample where an IDS/IPS is not used. What are your load factors on the Dashboard?
