We have two ISP related DNS servers with each behind a pa-3020. During peak time we have seen the number of sessions increase to 150K on each pa-3020 so we were concerned that if one DNS server had to take the whole load then the pa-3020 would go over the 256k session limit. We decided that we needed to move the DNS servers each behind a pa-3050. The pa-3020is were running 4-6% cpu on the dataplane. Much to our surprise when each are behind their own pa-3050, the dataplane cpu running 50-60%. So of instead of the dataplane cpu going down, it went up 10 fold. Has anyone else seen this type of performance issue with the pa-3050. Support does not think that there is an issue.
