#SQL-Benchmark
A synthetic benchmark to compare the performance of various sql-drivers for Go's database/sql package
- March 19, 2013 // OS X 10.8.3 / MySQL 5.6.10 by Arne Hormann
- March 19, 2013 // Linux / MySQL 5.5.27 by Arne Hormann
- Intel Core i5-2500K (4x 3.30 GHz), 8 GB RAM
- MySQL 5.5.34
- Ubuntu 13.10 x64 (Linux)
- Go 1.2rc2 linux/amd64
- Go-MySQL-Driver v1.1 and v1.0.2 and MyMySQL v1.5.3
- fresh & clean install via
apt-get install mysql-server - server version: 5.5.34-0ubuntu0.13.10.1
- connected via Unix Domain Socket (
/var/run/mysqld/mysqld.sock) - additional config:
thread_cache_size = 16
query_cache_limit = 2M
query_cache_size = 128M
- CPU frequency governor set to 'performance'
- We did a complete rewrite of the benchmark suite for this round. The results are not comparable to previous rounds.
- The results should now be much more accurate and vary less.
- The benchmark suite now includes concurrent tests. These are probably the most interesting tests.
- The memory footprint (per query) is now also measured.
- Before each test the Garbage Collector is manually run to eliminate influence of garbage from previous tests.
- The benchmarks are designed to minimize response latency from the server. We try to compare driver performance here and not to benchmark the MySQL Server ;)
- The memory footprint includes allocations by the database/sql package. In fact, for Go-MySQL-Driver 1.1 this is the large part, as you can see in this memory profile. The
mysql-rows.(*mysqlRows).Columnsblock will hopefully eliminated after the Go 1.2 release with this patch.
