Re: s...l...o...w... ppp xfers
Quoting Rick Hayter ([EMAIL PROTECTED]): Slink is working like a champ in all aspects but ppp connection speed. Actually, I connect at high speeds, but my sustained throughput runs from only 200-400 bps! When first downloading, I get a burst of speed, but in seconds all activity seems to stop then another short transfer burst... A totally unrelated approach... Have you looked at the traffic? Eg, with tcpdump -l ppp0 or somesuch. I had this problem when I took a box from work home with me, and it had been set up to run iplogger. Throughput was lousy because of a huge amount of nameserver traffic. dpkg --remove iplogger at the home end fixed the problem instantly. (The majority of the traffic all had the same port number in it, and fuser linked it to the pid which was iplogger's.)

RE: s...l...o...w... ppp xfers
I'm looking for some troubleshooting help. Slink is working like a champ in all aspects but ppp connection speed. Actually, I connect at high speeds, but my sustained throughput runs from only 200-400 bps! When first downloading, I get a burst of speed, but in seconds all activity seems to stop then another short transfer burst... then another pause... etc. (I am using an external modem that works fine in windoze98). Am I looking at a buffer overflow or handshake problem? What should I do to help diagnose this? Thanks! Me, again... this is still unsolved. I've tried the two solutions offered: 1. echo 0 /proc/sys/net/ipv4/tcp_timestamps 2. try turning off all compression by ppp Neither one helped (though by turning off compression my throughput MAY have gone up to 500-600 bps.) I've attached my ppp.log and debug.log for any kind sole that wants to dive in! :-) - Rick

try: echo 0 /proc/sys/net/ipv4/tcp_timestamps If that does not help, try turning off all compression by ppp (header compression and the like) and let only the modem do the compression.

My current connection is to a modem-pool and once in a while the throughput is fairly good, but average is around .3K/sec. I thought it was something with the way the modems work on their end. Previously I was connected to the university here (also a modem pool) and throughput was consistantly 2 - 3 K/sec. Same modem on my end, same system. Interesting question...
