EIDE Conner 850 MB drive. PCI NE2000 compatible network adapter Machine B: AMD K5-90 ASUS T2P4 motherboard 32 MB EDO AHA 1542 C SCSI host adapter Quantum Maverick 500 MB hard drive Toshiba 3701B CD-ROM Wangtek 5099 60MB QIC tape drive ISA NE0000 compatible network adapter A and B are connected via standard coax cable (3m). Termination resistors are properly used. I have checked the resistance with my OHM-meter and all is fine. No the problem: On B I am running the samba server. Sometimes it is necessary for me to run Winloose NT 4 on the Pro and it is nice when I can access files from B. But the samba performance is very bad. When the Pentium Pro machine (A) copies files from B than only 200 KB/s are achived. FTP from A to B and vice versa as well as the TCP benchmark tcpblast show the almost full performance of 1.1 MB/s. But when I run smbclient I only get 330 KB/s. smbclient locally on B delivers 5 MB/s or more. Therefore my question: Why is samba so slow when the network connections between the two machines are ok? What's going on there? On A I'm running 3.0-current, on B 2.2.2. TIA Robert
