Internet stress tools are a set of stress tools for TCP/UDP. It runs under Linux.
tcp_sender can be used to create and handle many concurrent TCP connections divided between a small number of threads.
Usage: bin/tcp_sender [OPTIONS] <address>
<address>: socket address where to connect to. Possible formats:
<host>:<port>: IPv4/IPv6 address and port.
Unix socket: Unix socket as absolute path.
Options:
--connections <count> (range: 1 - 32768, default: 1).
--threads <count> (range: 1 - 32, default: 1).
--receive <count>: number of bytes to receive (range: 0 - 32768, default: 0).
--thread-loops <count>:
Number of iterations per thread
(range: 1 - 18446744073709551615, default: 1).
--connection-loops <count>:
Number of iterations send/receive per connection
(range: 1 - 18446744073709551615, default: 1).
--client-sends-first | --server-sends-first:

--set-read-write-event | --do-not-set-read-write-event:

--processors <processor-list> | "even" | "odd".
<processor-list> ::= <processor>[,<processor>]*
--file <filename>: file to be sent. --file <filename> can be used multiple times.
If not specified, a dummy file of 1400 bytes is sent.
tcp_receiver can be used to handle many concurrent TCP connections divided between a small number of threads.
Usage: bin/tcp_receiver [OPTIONS] <address>
<address>: socket address where to bind to. Possible formats:
<host>:<port>: IPv4/IPv6 address and port.
Unix socket: Unix socket as absolute path.
Options:
--threads <count> (range: 1 - 32, default: 1).
--receive <count>: number of bytes to receive (range: 1 - 32768, default: 1400).
--connection-loops <count>:
Number of iterations send/receive per connection
(range: 1 - 18446744073709551615, default: 1).
--client-sends-first | --server-sends-first:
Who sends data first? (default: --client-sends-first).
--set-read-write-event | --do-not-set-read-write-event:
Should both events be set or only one? (default: --set-read-write-event).
--single-listener | --one-listener-per-thread:
Same listener for all the threads or a listener per thread?
(default: --one-listener-per-thread).
--single-epoll-fd | --one-epoll-fd-per-thread:
Same epoll fd for all the threads or a epoll fd per thread?
(default: --one-epoll-fd-per-thread).
--processors <processor-list> | "even" | "odd".
<processor-list> ::= <processor>[,<processor>]*
--file <filename>: file to be sent. --file <filename> can be used multiple times.
udp_sender can be used to send many UDP messages divided between a small number of threads.
Usage: bin/udp_sender [OPTIONS] <address>
<address>: socket address where to send messages to. Possible formats:
<host>:<port>: IPv4/IPv6 address and port.
Unix socket: Unix socket as absolute path.
Options:
--messages-per-send <count> (range: 1 - 4294967295, default: 1).
--sends <count> (range: 1 - 18446744073709551615, default: 1).
