amp throughput
amp-throughput - AMP standalone TCP throughput test
amp-throughput -s [options]
amp-throughput -c server [options]
amp-throughput is the standalone version of the amplet2(8) TCP throughput test. It is very similar in function to iperf(1), except that it can also use a running instance of amplet2(8) as a server, authenticating the connection using SSL.
-p, --port port
Set server control port to connect to/listen on to be port. The
default is 8815.
-I, --interface iface
Specifies the interface (device) that tests should use when sending
packets. By default the interface will be selected according to the
routing table.
-4, --ipv4 a.b.c.d
Specifies the source IPv4 address that tests should use when sending
packets to IPv4 targets. This address must belong to one of the
interfaces. By default the IPv4 address of the outgoing interface will
be used.
-6, --ipv6 a:b:c:d:e:f:g:h
Specifies the source IPv6 address that tests should use when sending
packets to IPv6 targets. This address must belong to one of the
interfaces. By default the IPv6 address of the outgoing interface will
be used.
-s, --server Run in server mode.
-c, --client host
Run in client mode, connecting to host.
-i, --rcvbuf bytes
Set the maximum size of the socket receive (input) buffer to bytes
bytes. The default is set by /proc/sys/net/core/rmem_default.
-M, --mss bytes
Set the TCP maximum segment size to bytes bytes.
-N, --nodelay Disable Nagle's Algorithm (set TCP_NODELAY).
-o, --sndbuf bytes
Set the maximum size of the socket send (output) buffer to bytes
bytes. The default is set by /proc/sys/net/core/wmem_default.
-P, --test-port port
Perform the actual throughput test using port port. The default is
8816.
-Q, --dscp codepoint
IP differentiated services codepoint to set. This should be a string
representing a 6-bit value in binary, octal, decimal or hexadecimal, or the
short name of a predefined, commonly used codepoint. The default is 0.
-r, --randomise Randomise the contents of each test packet sent.
-S, --schedule sequence
Test schedule describing direction and duration of tests (see below). The default is to test for 10 seconds from the client to the server.
-t, --time seconds
Test from client to server for seconds seconds. The default is 10
seconds.
-w, --disable-web10g Don't record Web10G results (if they are available).
-z, --write-size bytes
Use bytes bytes sized writes when writing data to the socket. The
default is 131072 bytes (128KB).
-h, --help Show summary of options.
-v, --version Show version of program.
-x, --debug Enable extra debugging output.
Socket options such as rcvbuf, sndbuf, mss and nodelay will be set on both the client and the server. The client sends the options across the control socket and they will get set on the test socket at both endpoints. Web10G can be used to check these are set correctly.
A schedule is a sequence of tests. Each test starts with a single character representing the type. Tests are separated by a single comma. Valid types are:
s*bytes*
Run a server -> client test, sending data until bytes bytes have
been sent.
S*bytes*
Run a client -> server test, sending data until bytes bytes have
been sent.
t*milliseconds*
Run a server -> client test, sending data for milliseconds
milliseconds.
T*milliseconds*
Run a client -> server test, sending data for milliseconds
milliseconds.
n Make a new test connection (close and reopen it).
p*milliseconds*
Pause sending for milliseconds milliseconds.
amp-thoughput -c <target> -S t10000,T10000 Run a server to client test for 10 seconds, then run a client to server test for 10 seconds across the same connection.
amp-thoughput -c <target> -S s16000,n,S24000 Run a server to client test sending 16,000 bytes, then close and reopen the connection before running a client to server test sending 24,000 bytes.
amplet2(8), amplet2-remote(8), amp-icmp(8), amp-trace(8), amp-dns(8), amp-http(8), amp-tcpping(8), amp-udpstream(8).
