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