Redis benchmark shows unix domain socket can be significant faster than TCP loopback. … Depending on the platform, unix domain sockets can achieve around 50% more throughput than the TCP/IP loopback (on Linux for instance). The default behavior of redis-benchmark is to use the TCP/IP loopback.
Are UNIX sockets fast?
“Unix sockets. They are faster.”, they’ll say. … Unix sockets are a form of inter-process communication (IPC) that allows data exchange between processes in the same machine.
What is the difference between Unix socket and TCP port?
A UNIX socket is an inter-process communication mechanism that allows bidirectional data exchange between processes running on the same machine. … A TCP/IP socket is used for communication across TCP/IP networks. A connected TCP socket is identified by the combination of local IP, local port, remote IP and remote port.
Is TCP a UNIX socket?
Socket Use In Practice
Unix sockets are usually used as an alternative to network-based TCP connections when processes are running on the same machine.
What are UNIX sockets used for?
A Unix domain socket or IPC socket (inter-process communication socket) is a data communications endpoint for exchanging data between processes executing on the same host operating system.
Do Unix sockets use ports?
When the host is “localhost”, MySQL Unix clients use a Unix socket, AKA Unix Domain Socket, rather than a TCP/IP socket for the connection, thus the TCP port doesn’t matter.
Do Unix sockets have ports?
For our purpose, a port will be defined as an integer number between 1024 and 65535. … This is because all port numbers smaller than 1024 are considered well-known — for example, telnet uses port 23, http uses 80, ftp uses 21, and so on.
What is TCP UNIX socket?
A UNIX socket is an inter-process communication mechanism that allows bidirectional data exchange between processes running on the same machine. IP sockets (especially TCP/IP sockets) are a mechanism allowing communication between processes over the network.
What is UNIX socket path?
UNIX domain sockets are named with UNIX paths. For example, a socket might be named /tmp/foo. UNIX domain sockets communicate only between processes on a single host. … Socket types define the communication properties visible to a user. The Internet domain sockets provide access to the TCP/IP transport protocols.
