Network problem

(ticket 897715704)
My customers complain for lags and slow network.
I try debug it => get traceroute (client <==> server) but its look good.

Then I check network speed.
Code:
wget http://rbx.proof.ovh.net/files/1Gio.dat -O /dev/null
wget http://bhs.proof.ovh.net/files/1Gio.dat -O /dev/null
wget http://sbg.proof.ovh.net/files/1Gio.dat -O /dev/null
wget http://gra.proof.ovh.net/files/1Gio.dat -O /dev/null
wget http://speed.hetzner.de/1GB.bin -O /dev/null
wget http://mirror.leaseweb.com/speedtest/1000mb.bin -O /dev/null
wget http://speedtest-fra1.digitalocean.com/100mb.test -O /dev/null
== slow network ==
Some strange => if you try a few times wget => get very slow.
