This is a command-line tool that will run a predefined set of benchmark tests on CPU and memory, the file system, and a SQL Server database. This allows you to get a comparative summary between different servers. CPU and memory tests are always run locally. File and SQL tests can be run locally or remotely (UNC path for file and remote SQL Server respectively).
Bill moved his SQL Server from a regular computer to a VM. His users complain their apps run slower.
- From a client machine, run the SQL test to the old SQL Server and the new SQL Server and compare.
- From a client machine, run the file test to both SQL Servers and compare. Maybe the virtual network is slower?
- Run the CPU test on both SQL Servers. Are the CPU stats significantly different?
Jane upgraded from SQL 2012 to SQL 2019 on a new machine. Users complain it’s slower on the new machine.
- From a client machine, run the SQL test to the old SQL Server and the new SQL Server and compare.
- From a client machine, run the file test to both SQL Servers and compare. Maybe the network card is slower?
- Run the CPU test on both SQL Servers. Are the CPU stats significantly different?
SQLBENCH.EXE [-n timestorun] [-cpu] [[-file "folderpath"]...] [[-sql "connectionstring"]...] [-output "folderpath"]
-n the number of times to run the test(s)
-cpu starts the CPU test
-file starts the I/O test
-sql starts the SQL Server test
-output the output path where various output files are written (MathTests.csv, Database.csv, File.csv). The path must already exist.
- Download SQL_BENCH.ZIP v1.0.240.0
- Extract SQLBENCH.EXE to a folder of your choice. It is ready to use.
This is a C# application that requires the full .NET 4x framework on Windows.
SQLBENCH does not require Administrative permissions, but you must have permission to the folder, file share, or SQL Server database that you are benchmarking.
- All tests write to the Console Window and a file called TestLog.txt
- CPU/memory test writes a file called MathTests.csv to the current folder or a folder of your choice
- File test creates a file called test123.bin in the specified folder (-file switch) and reads and writes to it. It writes to a file called File.csv
- The SQL test creates a TABLE called P1 in the server and database specified and reads and writes to it. It writes to a file called Database.csv (the specified database must already exist before the test)
Important: This tool does not communicate with any external systems other than a SQL Server or File Server as specified in the command line and to write the three log files to the current folder or the folder specified. It does not modify the system in any way other than as described above. The test table is removed at the end of the run.
