VSX Performance issue on r80.30 take 219 (3.10)

Hi CheckMates,

 

I'm encountering an issue since 4 months, after a migration from old 14000 boxes running on r77.30 to 15000series on r80.30.

 

CPU cores were saturation could be seen imediatly after the migration, 4 Months of investigation with TAC, first issue identified was a bug that most of tcp 443/445 tarfic was taking the medium path, we used fast accel feature to staticly accelerate it, this bug should have been fixed in JHF 219, and indeed it seems to as we dont use fast accel today.

 

But the performance is still an issue,  our FWKs are maxed out, and thus all Cores related during bussiness day.

 

Technical infos  :

VSX cluster running r80.30 take 219 new kernel.

Blades : FW + IPS

Main VS  runing 18 fwk instances.

 

All cpu cores handeling VS traffics are on avg 80% usage, and most of them maxing out during bussiness hours.

 

We have no lead atm with TAC (prety slow response, and knowledge to be honest).
