And I thought it was my imagination!
I have noticed a similar problem with the diald / ISDN setup we have here.
I have a P90 16Mb with an external USR Courier I configured to run at
64kbps. Connections go through OK but quite often (not always) and
especially using ftp on that machine I'll get a fast transfer rate (7-8
k/s) which then drops down to about 3.6k/s and stays fairly constant. I'm
dialling into Demon and getting this response on the test files on their
local ftp server so I don't see that there should be much network lag
involved.
One problem I did have was that I attempted to set the serial port to run
at 230400 (it's supposed to be capable) using spd_cust and a custom
divisor. This seemed to make things even slower! When I dropped it back to
115200 (spd_vhi) , things sped up but I still get this strange slowing-down
effect with constant volumes of data.
I'm running kernel 2.0.29

Subject: DialD, External ISDN, and really slow connections.
Hello all.
Im at the pulling my hair out stage now! Could someone try to shed some
light on what I might be doing wrong here.
Heres the problem.
I have a Linux Box (P2 233 / 128Mb ram Kernel 2.0.33) with an external
Hayes
ISDN 128K Modem. I'm dialing into Easynet as the ISP but I have the same
problem with almost every other ISP I try as well.
The connection goes through really well, the ip-up script is run and all
seems to be working well, until I try to use the connection. The instant I
start to use the connection it slows down to a crawl. FTPing from the
Linux
machine to an ftp server at the ISP gives me a through put of about 1.5 K
maximum.
I would guess there might be something set wrong in the kernel, but its
only
a guess.
I have tried everything I can think of but I still have the same problems.
Just to confuse the issue even more, if I use an external 56K Hayes modem
instead it runs really quick and all is fine.
Thanks in advance for your help
