TCPproxy: Throttle your TCP connections now!
$ npm install -g tcpproxy
The default command will delay each TCP connection one second and redirect port 8080 to 80:
$ tcpproxy -a www.google.com
Finish transfer! -- Time: 150 ms -- Client: 76 bytes -- Server: 18352 bytes
Finish transfer! -- Time: 160 ms -- Client: 76 bytes -- Server: 18310 bytes
You can throttle the connection with many other options, for example with 10 bytes per 100 milliseconds:
$ tcpproxy -a www.google.com --bps 10/100
Other options:
-b, --bindAddress <host> Local address where the proxy should be bind,
default 127.0.0.1
-l, --bindPort <port> Local port where the proxy should be bind,
default 8080
-a, --originAddress <host> Address of the origin server, required
-p, --originPort <port> Port of the origin server, default 80
-d, --delayConnection <ms> Delay in millisecond until the connection will
be established to the origin server,
default 1000ms
--bps, --delayBytesPerSecond <b/ms> Delay bytes per millisecond (bytes/millisecond)
--delayChunkFromClientToOrigin <ms> Delay chunk from client to origin in millisecond
--delayChunkFromOriginToClient <ms> Delay chunk from origin to client in millisecond
