I have been trying various methods +of getting win95 to talk to Samba quicker. The results I have come up with +are: + +1. Install the W2setup.exe file from www.microsoft.com. This is an +update for the winsock stack and utilities which improve performance. + +2. Configure the win95 TCPIP registry settings to give better +perfomance. I use a program called MTUSPEED.exe which I got off the +net. There are various other utilities of this type freely available. +The setting which give the best performance for me are: + +(a) MaxMTU Remove +(b) RWIN Remove +(c) MTUAutoDiscover Disable +(d) MTUBlackHoleDetect Disable +(e) Time To Live Enabled +(f) Time To Live - HOPS 32 +(g) NDI Cache Size 0 + +3. I tried virtually all of the items mentioned in the document and +the only one which made a difference to me was the socket options. It +turned out I was better off without any!!!!! + +In terms of overall speed of transfer, between various win95 clients +and a DX2-66 20MB server with a crappy NE2000 compatible and old IDE +drive (Kernel 2.0.30). The transfer rate was reasonable for 10 baseT. + +The figures are: Put Get +P166 client 3Com card: 420-440kB/s 500-520kB/s +P100 client 3Com card: 390-410kB/s 490-510kB/s +DX4-75 client NE2000: 370-380kB/s 330-350kB/s + +I based these test on transfer two files a 4.5MB text file and a 15MB +textfile. The results arn't bad considering the hardware Samba is +running on. It's a crap machine!!!! + +The updates mentioned in 1 and 2 brought up the transfer rates from +just over 100kB/s in some clients. + +A new client is a P333 connected via a 100MB/s card and hub. The +transfer rates from this were good: 450-500kB/s on put and 600+kB/s +on get. + +Looking at standard FTP throughput, Samba is a bit slower (100kB/s +upwards). I suppose there is more going on in the samba protocol, but +if it could get up to the rate of FTP the perfomance would be quite +staggering. + +Paul Cochrane + |
