> Is iperf affected by IPoIB MTU size when used with librspreload.so ?

Another strange issue:

$ sudo LD_PRELOAD=/usr/local/lib/rsocket/librspreload.so iperf -c 172.17.0.2
------------------------------------------------------------
Client connecting to 172.17.0.2, TCP port 5001
TCP window size:  128 KByte (default)
------------------------------------------------------------
[  3] local 172.17.0.1 port 57926 connected with 172.17.0.2 port 5001
[ ID] Interval       Transfer     Bandwidth
[  3]  0.0-10.0 sec  12.2 GBytes  10.4 Gbits/sec

$ iperf -c 172.17.0.2
------------------------------------------------------------

rsocket slower than IPoIB ?
