where can i see/check the real mtu/mru size used during the communication ?

i have put in my /etc/ppp/options file these Two lines :

mtu n
mru n

Ï ve made several tests :

default size of mtu/mru -> ~99.0Kbytes/sec.

296 -> ftp: 9128953 bytes sent in 528.71Seconds 17.27Kbytes/sec.
4096 -> ftp: 9128953 bytes sent in 92.44Seconds 98.76Kbytes/sec.
16384 -> ftp: 9128953 bytes sent in 95.79Seconds 95.30Kbytes/sec.

which is the mximum mru/mtu size ? i cannot go over 16384 bytes ...

Why my rate is always so poor ? Why my rate is the same with same default
size (1500) and the max size ? Does the mtu/mru size is important to have
good rating on a clear network (10Mb switched) ? I don't understand whereis
my problem ... :(

Thanks.
