- =============================================================================
-
- This might be relevant to Client Tuning. 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.
