We have 10Gb network to our two RGW nodes behind a single ip on

look okay. However, when using a small cosbench cluster I am unable to
get more than ~250Mb of read speed total.
A few thoughts:
i) have you benchmarked your ceph itself (i.e. with rados bench - you'll
want to parameter-sweep with how many clients you run (and/or
threads/client))? That gives you a more useful baseline
ii) what does your RGW node load look like? On our RGW nodes we can
eventually use up all the available CPU, but that required tuning both
cosbench (which you look to have tried) and civetweb - rgw num rados
handles and num_threads in rgw frontends
iii) is haproxy your rate-limiter? We had to significantly increase
nbthread on our haproxy
HTH,
