Summary0000223: Upload speed very slow when using fast PPPoE connection and gigabit internal network.
DescriptionUploading to the WAN port gives only 1,5MB/s upload on 100mbit PPPoE connection, when having 1000mbit internal LAN network.
the LAN network is fully operational at all times (1000Mbit/s transfer), the ClearOS machine is able to upload on the WAN port with full 100mbit, the only problem is the lan machine > internet upload.
If the LAN network is 100mbit (or forced to 100mbit) the upload speed from the intenral network to internet is full 100mbit. if both interfaces LAN and WAN operate at 1000mbit the problem still persists.

The solution to this is to set the synchronous option to yes in /etc/sysconfig/network-scripts/ifcfg-ppp0

It would be very good to have this option in the web admin (like the MTU option), because its very useful for faster PPPoE connections. This is not just ClearOS issue, it is explained here:

The same machines, when using static IP instead of PPPoE for WAN connection (same ISP, just another router in front of them) were able to achive full 100mbit upload speed from the lan network to the internet (via ftp upload for example)

I wanted to add another thing:
When using the synchronous="yes" option, for some reason i was getting ALOT of RX errors on the ppp0 interface - like 1000 per second. I didnt had any packet loss during ping, or other problems, but it was very annoying to see them in the ifconfig and the hardware report so i checked around the net and finally resolved the problem by adding this line to /etc/sysconfig/network-scripts/ifcfg-ppp0 :
LINUX_PLUGIN=/usr/lib/pppd/2.4.3/rp-pppoe.so
also to /lib/modules/2.6.18-194.8.1.v5/modules.alias :
alias tty-ldisc-3 ppp_async
alias tty-ldisc-13 n_hdlc
The last two lines may not be needed, but are specified in the KERNEL-MODE-PPPOE file of rp-pppoe so i added them.
----------
I havent tested this on different machines, so i cannot confirm its needed for everyone who use the synchronous mode, but its a good thing to consider.
