T2600G-28TS - Problem with LACP and Jumbo Frame

Hi guys,
I'm writing here because I need your precious help.
I think to probably have a little problem of configuration on my network and I'llI try to explain in simple way the problem and my network's configuration. Thanks to all for support and patience !
I have an ASUS AC87U Router, a T2600G-28TS and two identical client with AMD FX 8350 processor, 32 Gb of ram and a SSD as primary disk.
In each of these two clients I have installed aHP 331T Quad Port 1GbE Network Adapter (which is moved by a Bradcom chipset and which is managed using Bradcom Advanced Control Suite 4).
Using Broadcom Control Suite I create a Team using all 4 lan port and on my T2600G-28TS I did a link aggregation (4 lan port of the switch for the first pc and other 4 lan port of the switch for the second PC).
The cables are CAT6A FTP,
The problem is that when I try to transfer data from PC1 to PC2 (form a source folder that on PC1 is on SSD to a target folder that on PC2 is always on a SSD) I don't see throughput of the Team adpater which I can see regularly working under lan device of my Windows 10.
Team device show 4Gbit connection while data transfer is of 130 Mbyte (so more near to a 1Gbit connection).
In my idea I think to reach 300-400 Mbyte of speed but it isn't. There is something wrong in my idea?
I did some test using iperf and i decide to work on the same pc as server and as client infact from a DOS command line I launched this command :
iperf3.exe -s -i 5
and from a second DOS command line :
iperf3.exe -c ipserver -t 60 -i 5
and this is the result:
[ ID] Interval Transfer Bandwidth
[ 5] 0.00-60.00 sec 0.00 Bytes 0.00 bits/sec sender
[ 5] 0.00-60.00 sec 26.2 GBytes 3.74 Gbits/sec receiver
It seem to be correctly aggregated but I can see this speed when I move data from PC1 to PC2. Can be a reason? Could I check something on the switch?
The second problem is jumbo frame.
I set MTU 9000 to all 4 lan adapter of the HP 331T Quad Port 1GbE Network Adapter, so Team adapter has 9000 MTU.
I try this command “ping IP address –f –l 9000" but the answer is that packet need to be fragmented and I don't undestand the reason.
On the switch (for the first PC) in LAG session I have
Hash Algorithm SRC IP + DST IP
Detail info :
I don't know reason why bps field are blank.
I hope to be sufficiently clear in the exposition. If you need more info please tell me .
Thanks you very much for time and support that you will dedicated to me.
