DESCRIPTION ----------- benchmarking tool for HTTP/2 and SPDY server .. describe:: Specify URI to access. Multiple URIs can be specified. URIs are used in this order for each client. All URIs are used, then first URI is used and then 2nd URI, and so on. The scheme, host and port in the subsequent URIs, if present, are ignored. Those in the first URI are used solely. OPTIONS ------- .. option:: -n, --requests= Number of requests. Default: ``1`` .. option:: -c, --clients= Number of concurrent clients. Default: ``1`` .. option:: -t, --threads= Number of native threads. Default: ``1`` .. option:: -i, --input-file= Path of a file with multiple URIs are separated by EOLs. This option will disable URIs getting from command-line. If '-' is given as , URIs will be read from stdin. URIs are used in this order for each client. All URIs are used, then first URI is used and then 2nd URI, and so on. The scheme, host and port in the subsequent URIs, if present, are ignored. Those in the first URI are used solely. .. option:: -m, --max-concurrent-streams=(auto|) Max concurrent streams to issue per session. If "auto" is given, the number of given URIs is used. Default: ``auto`` .. option:: -w, --window-bits= Sets the stream level initial window size to (2\*\*)-1. For SPDY, 2** is used instead. Default: ``30`` .. option:: -W, --connection-window-bits= Sets the connection level initial window size to (2**)-1. For SPDY, if is strictly less than 16, this option is ignored. Otherwise 2\*\* is used for SPDY. Default: ``30`` .. option:: -H, --header=
Add/Override a header to the requests. .. option:: -p, --no-tls-proto= Specify ALPN identifier of the protocol to be used when accessing http URI without SSL/TLS. Available protocols: spdy/2, spdy/3, spdy/3.1 and h2c-14 Default: ``h2c-14`` .. option:: -d, --data= Post FILE to server. The request method is changed to POST. .. option:: -v, --verbose Output debug information. .. option:: --version Display version information and exit. .. option:: -h, --help Display this help and exit. OUTPUT ------ requests total The number of requests h2load was instructed to make. started The number of requests h2load has started. done The number of requests completed. succeeded The number of requests completed successfully. Only HTTP status code 2xx or3xx are considered as success. failed The number of requests failed, including HTTP level failures (non-successful HTTP status code). errored The number of requests failed, except for HTTP level failures. status code. This is the subset of the number reported in ``failed`` and most likely the network level failures or stream was reset by RST_STREAM. status codes The number of status code h2load received. traffic total The number of bytes received from the server "on the wire". If requests were made via TLS, this value is the number of decrpyted bytes. headers The number of response header bytes from the server without decompression. For HTTP/2, this is the sum of the payload of HEADERS frame. For SPDY, this is the sum of the payload of SYN_REPLY frame. data The number of response body bytes received from the server. time for request min The minimum time taken for request and response. max The maximum time taken for request and response. mean The mean time taken for request and response. sd The standard deviation of the time taken for request and response. +/- sd The fraction of the number of requests within standard deviation range (mean +/- sd) against total number of successful requests. time for connect min The minimum time taken to connect to a server. max The maximum time taken to connect to a server. mean The mean time taken to connect to a server. sd The standard deviation of the time taken to connect to a server. +/- sd The fraction of the number of connections within standard deviation range (mean +/- sd) against total number of successful connections. time for 1st byte (of (decrypted in case of TLS) application data) min The minimum time taken to get 1st byte from a server. max The maximum time taken to get 1st byte from a server. mean The mean time taken to get 1st byte from a server. sd The standard deviation of the time taken to get 1st byte from a server. +/- sd The fraction of the number of connections within standard deviation range (mean +/- sd) against total number of successful connections. FLOW CONTROL ------------ h2load sets large flow control window by default, and effectively disables flow control to avoid under utilization of server performance. To set smaller flow control window, use :option:`-w` and :option:`-W` options. For example, use ``-w16 -W16`` to set default window size described in HTTP/2 and SPDY protocol specification.
