The first tests I did where with a routed topology through 2 StarVX routers but these most recent tests is with all interfaces bridged and the StarVX client as a wireless client bridge which I believe is based on WDS.
If your asymmetric performance with the RB532's is between 12 and 18mbps I wouldn't say your seeing similar performance as I am seeing 40mbps and 27.7mbps when transmitting and receiving at the same time using random (uncompressible) tcp based data. The tests are based on default packet sizes however, we run M3P (ip packing) between the Mikrotiks and when testing with small packets (50-100byte) I see the same results. The only problem with M3P is that it adds 15ms of delay in each direction under low loads. This means you see pings with a round trip time of +30ms. This does however improve when more and more traffic is passed over the link as M3P either waits for 1500bytes of traffic or 15ms to expire (which ever comes first). The difference in upload and download speed I have so far put down to one system being a 2.4GHz CPU and the other being a 533MHz CPU. Hopefully I can test with 2 P4's later today.

Hey, as long as you're doubling as my personal IT lab... :) My tests so far have just been traditional AP/client mode, and I'm seeing the same sort of asymmetrical performance you are. With a pair of RB532s, depending on the "random-data" and packet size settings, I'm floating between 12 and 18Mbps. Thing is, I always get better performance with traffic going client-to-AP than AP-to-client. Have you, or will you, test with WDS mode? If you've already done so, are you getting better or worse performance that way? (I may or may not be able to try that particular setup before I leave for vacation on Friday. Probably not, because I've not worked with RouterOS' wireless stuff before and I may not be able to figure out how to set it up. :) Also, are you using the default packet sizes or have you been playing with those too? At least in wired network testing I've done before, the real worst-case scenario involves using the smallest packets you can get away with (because of the extra overhead in packet creation).
