Re: optimising tcpwindowsize and tcpbuffsizes

Chris,
TCPWINDOWSIZE should be set to 63 on Win2k.
apart from that ,have you tried
TxnGroupMax 256
TxnByteLimit 2097152(for BU direct to LTO or DLT)
TcpNoDelay yes
and maybe you can take an instr_client_detail trace and take a look at the
DataVerb figure, see if it's high.

Hi,
Does any one know a calculation or method for setting/optimising
tcpwindowsize and tcpbuffsize on Windows 2K machines?
I have currently set them to :
TCPBUFFSIZE 32
TCPWINDOWSIZE 61
But am still getting very slow speeds. Named pipes on the server gives me
about 13M a second where as TCP gives me about 3M
Any ideas would be greatly appreciated,
Cheers
Chris
