I need some help from those folks I've seen on this list with the speed problems. I noticed while printing to a smb printer from my Linux box tonight (which I just managed to get running) that the speed is horribly slow. I did some tests - the results follow. Transfer from Win98 to Linux ---------------------------- smb: \> get 1mbyte.txt getting file 1mbyte.txt of size 1024702 as 1mbyte.txt (772.134 kb/s) (average 772.134 kb/s) Transfer from Linux to Win98 ---------------------------- smb: \> put 1mbyte.txt putting file 1mbyte.txt as \1mbyte.txt (10.0143 kb/s) (average 10.0143 kb/s) After adding "socket options = TCP_NODELAY" to smb.conf I got the following: Transfer from Win98 to Linux ---------------------------- smb: \> get 1mbyte.txt getting file 1mbyte.txt of size 1024702 as 1mbyte.txt (814.89 kb/s) (average 814.891 kb/s) Transfer from Linux to Win98 ---------------------------- smb: \> put 1mbyte.txt putting file 1mbyte.txt as \1mbyte.txt (9.99796 kb/s) (average 9.99796 kb/s) As you can see there was a significant improvement in the download (relative to Linux) speed, however the upload speed didn't change much. The same two tests with the same Linux box and an NT4 SP4 machine: smb: \> put 1mbyte.txt putting file 1mbyte.txt as \1mbyte.txt (719.4 kb/s) (average 719.4 kb/s) smb: \> get 1mbyte.txt getting file 1mbyte.txt of size 1024702 as 1mbyte.txt (840.912 kb/s) (average 840.912 kb/s) Obviously no problem here. One oddity - I do see many retransmissions and some "ACK too long (197ms)" messages on the sniffer when I watch the uploads to Win98. All three machines are on a local IP only subnet, 10Mbps HDX shared. Any suggestions would be appreciated! -- John J. LeMay Jr. NJMC, LLC. http://www.njmc.com
Which DUN tweaks does 98 have, or which have you installed? I had a similar problem Linux <-> 95 w/ DUN 1.3 installed. Performance was glacial on reads, and ftps from linux --> W95. I ended up reinstalling all the networking s/w, and have NOT yet reapplied the DUN fix ( I dont need VPN anymore ), and performance is passable (350-400 K/sec). ED

That sounds like a new FAQ to write: if the speed in one direction is 1/10 of the other, immediately check that the setting for speed and duplicity (;-)) on your ethernet cared matches your hub. This is usually a 10/100 half/full-duplex card that's confused... --dave -- David Collier-Brown, | Always do right.
