I got a RB532 with 2 wireless links using vlans connected to a linux box.I dont use any filters or packages in RB I use it only for the wireless connection. Although signals are perfect and I have tried all possible channels speed is low. I cant get total more than 30mbps in/out. I have even overclocked cpu to 399mhz. Configuration is very simple just the links and I bridge vlan and wlan nothing else. I dont use tracking firewall. i use it like a bridge device. CPu is always 100% when total bandwidth is over 15-20 mbps. I expected to get better speeds even with 1 wireless link I cant pass over 25mbps with turbo (signal -50). Seems like hardware cant handle more.
I would love any tweaks or advice what to do to improve perfomance as this is too low I dont expect much from RB but these speeds are too low.
If I use filter firewall queues then RB is dead

(now i use version 2.9.38 in any case there are known issues with some versions)
Thank you
