slow file saving on the network

Hello

when I open a file on the network and want to save the modifications, it s 8 times slower than doing the same localy.

I have tested on linux data server with samba and on a windows server and I come to the same slow result.

i have also tested with different switch and configuration on my network and virtualization (vlan with vswitch) it s the same slow result.

Any ideas ?

Regards,
