Hello, I upgraded our our Pix's OS from 6.3(4) to 6.3(5). We have a 14 site VPN Meshed network with 506s at remote sites and a 515 at the main site. After the upgrade we have been exipiriencing throughput issues at the main site (through the 515). Interface, bandwidth, CPU, and Memory stats are reading normal. Anyone have any thoughts on this?
