PostgreSQL 性能测试工具

postgresql 自带性能测试工具 pgbench

pgbench 是 postgresql 自带的交互性能测试工具。用于测试postgresql数据库性能。

为了测试postgresql数据库性能，简单测试如下

bash-4.2$ pgbench --help
pgbench is a benchmarking tool for PostgreSQL.

Usage:
pgbench [OPTION]... [DBNAME]

Initialization options:
-i           invokes initialization mode
-F NUM       fill factor
-s NUM       scaling factor
--index-tablespace=TABLESPACE
create indexes in the specified tablespace
--tablespace=TABLESPACE
create tables in the specified tablespace
--unlogged-tables
create tables as unlogged tables

Benchmarking options:
-c NUM       number of concurrent database clients (default: 1)
-C           establish new connection for each transaction
-D VARNAME=VALUE
define variable for use by custom script
-f FILENAME  read transaction script from FILENAME
-j NUM       number of threads (default: 1)
-l           write transaction times to log file
-M simple|extended|prepared
protocol for submitting queries to server (default: simple)
-n           do not run VACUUM before tests
-N           do not update tables "pgbench_tellers" and "pgbench_branches"
-r           report average latency per command
-s NUM       report this scale factor in output
-S           perform SELECT-only transactions
-t NUM       number of transactions each client runs (default: 10)
-T NUM       duration of benchmark test in seconds
-v           vacuum all four standard tables before tests

Common options:
-d             print debugging output
-h HOSTNAME    database server host or socket directory
-p PORT        database server port number
-U USERNAME    connect as specified database user
-V, --version  output version information, then exit
-?, --help     show this help, then exit
