Netzwerk-Datendurchsatz messenGeschwindigkeitsermittlung in Microsoft NetzwerkenUm den Datendurchsatz zwischen zwei Rechnern schnell und einfach zu messen, hilft das hier zum Download bereit stehende Tool: http://www.pcausa.com/Utilities/pcattcp.htm Am Empfänger-Rechner das Programm auf Komanndozeilen-Ebene mindestens mit folgendem Parameter starten:
pcattcp -r (receive modus) Nachfolgend noch eine Übersicht der Startparameter: The PCATTCP tool includes several options that are controlled by parameters passed on the command line when the program is started. To see the available options, run the PCATTCP application with the "-h" option. Here is what you would see: pcattcp -h PCAUSA Test TCP Utility V2.01.01.08 Usage: pcattcp -t [-options] host [ < in ] pcattcp -r [-options > out] Common options: -l ## length of bufs read from or written to network (default 8192) -u use UDP instead of TCP -p ## port number to send to or listen at (default 5001) -s toggle sinkmode (enabled by default) sinkmode enabled: -t: source (transmit) fabricated pattern -r: sink (discard) all received data sinkmode disabled: -t: reads data to be transmitted from stdin -r: writes received data to stdout -A align the start of buffers to this modulus (default 16384) -O start buffers at this offset from the modulus (default 0) -v verbose: print more statistics -d set SO_DEBUG socket option -b ## set socket buffer size (if supported) -f X format for rate: k,K = kilo{bit,byte}; m,M = mega; g,G = giga -c -t: send continuously -r: accept multiple connections sequentially -R concurrent TCP/UDP multithreaded receiver Options specific to -t: -n ## number of source bufs written to network (default 2048) -D don't buffer TCP writes (sets TCP_NODELAY socket option) -w ## milliseconds of delay before each write (default 0) -L ## desired transmit data rate in bytes/second Options specific to -r: -B for -s, only output full blocks as specified by -l (for TAR) -T "touch": access each byte as it's read
