The problem is solved now. It turned out *not* to be the fault of pfsense. Upgrading the firmware of my switches solved the problem - mostly. Now the throughput fluktuates (instead of being steady at a high rate): Peaks go up to 45MB/s, average is around 25-30MB/s (measured over ca. 5 minutes) through the firewall (compared to 117MB/s with a direct link). I observe some switching over to the slave CARP device when peak speed is reached, which is the cause for the much lower average.
The settings of Base and Skew values ("Virtual IP Address: Edit") of the slave device seem to be very delicate. Setting the base value too high kills practically the CARP switching, a good value for the skew I don't know. It seems to me that switching works good and fast with base=3 (around 3 seconds delay, intentionally?). For skew I set it to 50. What are your experiences with this? If you flood your pfsense with traffic, does it stay on the master or do you also see a switching to the slave? What are your skew settings? Is your throughput at a steady rate? Best regards, Adrian.
