I have just migrated from a Dell T105/UTM8 (2.3ghz Althlon 64x2) to a SuperMicro SYS-5015A-EHF-D525/UTM9 (Atom D525 1.8ghz, quad core), and have FiOS 150/150mbps service.
On the old system, I was able to "speedtest" at 80-90bps consistently (and higher than that consistently upload). On the new system, I'm seeing a pretty hard limit at around 25mbps down, 40mbps up.
If is SSH into the UTM9, I can wget a 100MB file across the internet at 18.1MB/s (~144Mbps). If I transfer the same file from a client computer, I get about 3MB/s (~24Mbps). If I do two clients at the same time fetching the same file, the sum of the two data rates is about 4MB/s (~32Mbps). When this is happening, I see a CPU usage of about 50% on the fw machine.
Is there any tuning I can do? The hardware and network are clearly capable of doing ~144Mbps, but nowhere near that is passing through the fw to clients. I think I can do better with this hardware -- i've seen pfsense benchmarks using this hardware that is capable of doing as high as 400-500Mbps.
Help?
