You don't have any ToughSwitches in there anyplace do you?

While running from R1 to R4 (maxing at only 10 Mbps), I can also run from R1 to R3 an additional 15+. Also, while running from R1 to R4 (again, maxing at 10 Mbps), I can also run from R3 to R4 an additional 60+. Aggregation on the M5 link is defaulted to 32 frames / 50,000 bytes. Could this be causing such issues on a good link?

I'm looking for any thoughts / suggestions. 4x MikroTik routers Link speeds: R1 -- (30 Mbps IP / Transport) -- R2 -- (100 Mbps Eth) -- R3 -- (75 Mbps UBNT M5) -- R4 The limiting factor for traffic should be the Transport, and I expect to be able to get 30 Mbps across the system (one-way). Testing from R1 to R3 runs 30 Mbps. Testing from R2 to R4 runs 75 Mbps. Testing from R1 to R4 only runs 10 Mbps (instead of 30). Tests were one-way btest with 20 TCP streams. Any ideas for something that would cause this?
