Problem
without qdisc 100mbit LAN (Sis900 AMD Duron 850 128RAM)-server
Realtek 8139 PIII-450 192RAN-client
I try ftp and ssh(scp)
upload ~7.5Mbyte/s
download ~8.5Mbyte/s
with tbf
tc qdisc add dev eth0 root tbf rate 1mbit burst 10k latency 50ms
download ~124kbyte/s
upload ~1500kbyte/s Why !!! (I try htb - the same problem)
if I change 1mbit to 100kbit upload ~150kbyte/s ???
if rate > 4mbit upload ~6.5Mbyte/s
i.e. if rate < 5mbit upload~\x10*download ???????
Any ideas !

And where do you execute that command? On the server?

You ceil the download to 1Mbit ( = 125 kbyte/s) and use all that bandwidth to
download. But when you upload at the same time, there are also packets going
in the download direction (confirmation packets and others). But your
download is full, so they can't get thru. That's why upload is also slow and
that's why you have to shape in both directions.
Or be clever, and give more bandwidth in the download direction for the
packets needed for upload

and do not use any ingress police

I shape only download from server where i use tbf or htb (I don't try cbq red and other )
and i find that the upload speed also down
when I delete qdisc or if the shaping speed > 5mbit/sd0kbyte/s
upload speed up to hardware limit ( in other case upload_speed~10*download_speed
download_speed < 2mbit/s furthure upload_speed approach to hardware limit)
I don't upload and download at the same time
I understand difference between bit and byte
I understand difference between egress and ingress
But I wonder when I detect it problem
It may be only my problem hardware, software etc.
I try to recompile kernel with patches, without patches and some different combination
of it(2.4.18 htb-3.4 patch imq-2.4.18.diff-9 patch
and some of patch-o-matic from iptables-1.2.6a - qouta,multiport,time,ttl,psd ....)
but nothing changed
It's impossible that the egress influence on upload speed of any way ???
Thank you for advance !!
(sorry from my English)

on 20.05.2002 I ask question about Upload rate also down
I think answer is that the TCP protocol issue when i upload to server
packets with answer from the server shaping and upload speed also down
I'm right ???
