with the new processor architecture, VSP ports no longer follow the 2 to 1 ration to the processor. previously in USPV 1 processor take care 2 FA ports. now the MP0/1/2/3... are not mapped to the ports but to the LUNs.
what do you think about the good/bad of this change? looks like we got some performance issues that is indirectly related to this architecture change.
