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