Dbench
Install
apt install dbench
Run
dbench [options]numclients tbench [options]numclientsserver tbench_srv [options]
Option
-c client.txt
Use this as the full path name of the client.txt file (the default is
/usr/share/dbench/client.txt).
-s Use synchronous file IO on all file operations.
-t TIME
set the runtime of the benchmark in seconds (default 600)
-D DIR set the base directory to run the filesystem operations in
-x enable xattr support, simulating the xattr operations Samba4 would need to perform
to run the load
-S Use synchronous IO for all directory operations (unlink, rmdir, mkdir and rename).
The tbench program takes a number, which indicates the number of clients to run
simultaneously, and a server name: tbench_srv should be invoked on that server
before invoking tbench. tbench can also take the following options:
-T option[,...]
This sets the socket options for the connection to the server. The options are a
comma-separated list of one or more of the following: SO_KEEPALIVE, SO_REUSEADDR,
SO_BROADCAST, SO_NODELAY, SO_LOWDELAY, SO_THROUGHPUT, SO_SNDBUF=number,
SO_RCVBUF=number, SO_SNDLOWAT=number, SO_RCVLOWAT=number, SO_SNDTIMEO=number,and
SO_RCVTIMEO=number. See socket(7) for details about these options.
The tbench_srv can only take one option: -T option[,...] as documented above.
