Each uplink is also connected with another OVS switch running on CentOS (S2, S3). Both, S2 and S3, have 2 interfaces each and are connected with 1,1 end host. All links are 1 Gbps.

However, if I run 2 long running flows, one of the flows get full throughput while the other's throughput drops to 400Mbps. I just want to confirm that OVS is not throttling the throughput. I have not changed any setting on OVS.

No, OVS should not be throttling traffic in that case.
