It's obviously dependent on many factors, but on reasonable hardware, I'd
expect gigabits per second.
yes, hardware is the first factor, but note also that without further
details on your test setup it is difficult to understand what are you
actually measuring: the bottleneck could be external to open vswitch
for example if you are using tap (with tunneling in user space) you are
typically spending lots of your CPU cycles in tunneling rather than
switching
see some results in the following paper

Mininet and on distributed SDN testbeds)”, 3rd European Workshop on
Software Defined Networks, EWSDN 2014, 1-3 September 2014, Budapest, Hungary
I have connected 2 VMs to an OVS switch using Tap interface which are on the
same network. When I sent packets(using PcktGen application) from 1 VM to
another, I get very low performance.
For 64byte packet size, the throughput is ~5Mbps, 128B packet size it is 9Mbps
and 254b packet size it is 16Mbps.
What is the maximum throughput that can be achieved with an OVS switch.
Thanks in advance.

Sharmila
