--0000000000006acd8305d2418be2 Content-Type: text/plain; charset="UTF-8" Pretty close to two years ago, we tripped across conditions where heavily used FreeBSD 11.x packet-filter firewalls would slow to a crawl and load would go crazy. In a fit of hopefulness with our upgrade to FreeBSD 13.0, I removed the hw.cxgbe.largest_rx_cluster settings we put in place -- only to have our hardest hit firewall experience high load and plummeting bandwidth within a few hours. So, I have two questions -- is there a better fix for this? Or, is the approach to set largest_rx_cluster to 4k and move on? Thanks in advance! --0000000000006acd8305d2418be2--
