CPU Increase when enabling AES-GCM

Supposedly AES-GCM should be the "best" cipher right now in terms of efficiency, however I noticed when enabling it on the F5, CPU goes up significantly. This is on a Viprion 2100 blade, 11.5.1 HF6....

Adding !SHA256 and !SHA384 will do the trick too. If SHA256 and SHA384 are an issue, that makes AES-GCM ciphers unusable until its fixed.

Nitass, are those published BugIDs? I can't find them on askf5.com.
