The post Benchmarking MySQL 8.0 Performance on Amazon EC2 appeared first on The WebScale Database Infrastructure Operations Experts.
]]>The scope of performance benchmarking
The core objective of this benchmarking exercise is to measure MySQL 8.0 performance, This include INSERTs , SELECTs and complex transaction processing (both INSERTs and SELECTs) without any tuning of MySQL 8 instance’s my.cnf. We agree tuning my.cnf will greatly improve performance but in this activity we wanted to benchmark MySQL 8 transaction processing capabilities and technically in MinervaDB we measure performance by Response Time and believe you can build high performance MySQL applications by writing optimal SQL. We have used Sysbench (https://github.com/MinervaDB/MinervaDB-Sysbench release 1.0.20) for this benchmarking activity. This is not a paid / sponsored benchmarking effort by any of the software or hardware vendors, We will remain forever an vendor neutral and independent web-scale database infrastructure operations company with core expertise in performance, scalability, high availability and database reliability engineering.

Benchmarking the memory workload
When we use sysbench to benchmark memory, sysbench allocate a memory buffer and then read or write from/on it, each time for the size of a pointer (32 bit or 64 bit) and until the total buffer size has been read from or written to. This activity will be continued till the provided volume (–memory-total-size) is reached. The load can be increased or reduced by providing multiple threads (–num-threads), size of buffer (–memory-block-size) and request type (read / write / sequential / random)
[root@localhost shiv]# sysbench --test=memory --num-threads=140 --memory-total-size=10G run

Benchmarking file system I/O with Sysbench
You can use multiple scenarios for benchmarking file system I/O but here we have used rndrw (combined random read / write) for more complex I/O and production similar I/O operations, This happens in three steps explained below:
- Prepare – Creates the files for testing
- Run – Performs the benchmarking and reporting
- Cleanup – Clean the system by deleting the files
Prepare

In the file system I/O benchmarking, We spend time annotating and interpreting only throughput (both reads and writes) under varying loads, Here in the test above read throughput is 40.89 MB/s and the write throughput is 27.26 MB/s

]]>The post Benchmarking MySQL 5.7 using Sysbench 1.1 appeared first on The WebScale Database Infrastructure Operations Experts.
]]>CPU – How long it takes for CPU to compute maximum primary number ? You may as well add how many threads are participating in this benchmarking process . This is very direct and easy way to benchmark the CPU performance.
File I/O – Benchmarking disk I/O performance considering all possible scenarios like direct io, sync, async etc. testing sequential reads / writes and random reads / writes , This makes an very scalable disk I/O benchmarking possible.
OLTP – Benchmarking MySQL under all possible workloads, like SELECT only queries (random / sequential SELECT) , INSERT / UPDATE / DELETE operations on multiple use case scenarios like bulk data loading, range-based updates, high volume data deletes (both random and sequential) etc. There is no MySQL benchmarking complete without Sysbench
Installing Sysbench
There are several ways to install Sysbench, It’s very well documented here – https://github.com/akopytov/sysbench#linux so we are not repeating it here again but we personally prefer installing Sysbench from source for many reasons so I have shared my method of installing Sysbench on CentOS

Benchmarking Disk I/O
The following I/O operations can be benchmarked using Sysbench :
- Sequential write – seqwr
- Sequential rewrite – seqrewr
- Sequential read – seqrd
- Random read – rndrd
- Random write – rndwr
- Combined random read/write – rndrw
Examples
Step 1 – Create a file , define total number of threads and file test mode. In the example below, we have selected combined random read/write (rndrw)
[root@localhost sysbench]# sysbench --num-threads=16 --test=fileio --file-total-size=2G --file-test-mode=rndrw prepare sysbench 1.1.0-651e7fd (using bundled LuaJIT 2.1.0-beta3) 128 files, 16384Kb each, 2048Mb total Creating files for the test... Extra file open flags: (none) Creating file test_file.0 Creating file test_file.1 Creating file test_file.2 Creating file test_file.3 Creating file test_file.4 Creating file test_file.5 Creating file test_file.6 Creating file test_file.7 Creating file test_file.8 Creating file test_file.9 Creating file test_file.10 Creating file test_file.11 Creating file test_file.12 Creating file test_file.13 Creating file test_file.14 Creating file test_file.15 ......... ............ Creating file test_file.125 Creating file test_file.126 Creating file test_file.127 2147483648 bytes written in 3.21 seconds (637.65 MiB/sec).
Step 2 – Run benchmarking test on file created above
[root@localhost sysbench]# sysbench --num-threads=16 --test=fileio --file-total-size=2G --file-test-mode=rndrw run
sysbench 1.1.0-651e7fd (using bundled LuaJIT 2.1.0-beta3)
128 files, 16MiB each
2GiB total file size
Block size 16KiB
Number of IO requests: 0
Read/Write ratio for combined random IO test: 1.50
Periodic FSYNC enabled, calling fsync() each 100 requests.
Calling fsync() at the end of test, Enabled.

Step 3 – Remove the files once completed benchmarking
[root@localhost sysbench]# sysbench --num-threads=16 --test=fileio --file-total-size=2G --file-test-mode=rndrw cleanup sysbench 1.1.0-651e7fd (using bundled LuaJIT 2.1.0-beta3) Removing test files...
Benchmarking MySQL using custom Lua scripts available with installation of Sysbench 1.1 (/usr/local/share/sysbench)
We have custom Lua scripts available with Sysbench 1.1 for benchmarking MySQL (I have listed them below)
[root@localhost sysbench]# ls bulk_insert.lua oltp_delete.lua oltp_point_select.lua oltp_read_write.lua oltp_update_non_index.lua select_random_points.lua tests oltp_common.lua oltp_insert.lua oltp_read_only.lua oltp_update_index.lua oltp_write_only.lua select_random_ranges.lua
Step 1 – create a MySQL database for running the benchmarking tests
mysql> create database sysbench; Query OK, 1 row affected (0.00 sec)
We have chosen “select_random_points.lua” script for benchmarking MySQL 5.7(default setting) in the example below :
Step 2 – Prepare sbtest1 table in sysbench database create above with 2M records
[root@localhost sysbench]# sysbench select_random_points.lua --table-size=2000000 --num-threads=1 --rand-type=uniform --db-driver=mysql --mysql-db=sysbench --mysql-user=root --mysql-password=SriLanka/2018 prepare sysbench 1.1.0-651e7fd (using bundled LuaJIT 2.1.0-beta3) Creating table 'sbtest1'... Inserting 2000000 records into 'sbtest1' Creating a secondary index on 'sbtest1'... [root@localhost sysbench]#
mysql> show table status like 'sbtest%' \G;
*************************** 1. row ***************************

Max_data_length: 0

Step 3 – Run the benchmark test using select_random_ponts.lua script , We have selected 100 threads for this test :
[root@localhost sysbench]# sysbench select_random_points.lua --table-size=2000000 --num-threads=100 --rand-type=uniform --db-driver=mysql --mysql-db=sysbench --mysql-user=root --mysql-password=SriLanka/2018 run
sysbench 1.1.0-651e7fd (using bundled LuaJIT 2.1.0-beta3)
Running the test with following options:
Number of threads: 100
Initializing random number generator from current time
Initializing worker threads...
Threads started!
SQL statistics:

ignored errors: 0 (0.00 per sec.)
reconnects: 0 (0.00 per sec.)
Throughput:
events/s (eps): 2799.2957
time elapsed: 10.0790s
total number of events: 28214
Latency (ms):
min: 0.15
avg: 35.50
max: 1727.81
95th percentile: 77.19
sum: 1001542.39
Threads fairness:
events (avg/stddev): 282.1400/13.24
execution time (avg/stddev): 10.0154/0.02
In the above report, time elapsed (at MinervaDB we measure performance by response time ) is most important matrix for me, Though we consider transactions / queries per second equally to measure the load in the system
Step 4 – Please don’t not forget to cleanup MySQL database created (sysbench in this example)
[root@localhost sysbench]# sysbench select_random_points.lua --table-size=2000000 --num-threads=100 --rand-type=uniform --db-driver=mysql --mysql-db=sysbench --mysql-user=root --mysql-password=SriLanka/2018 cleanup sysbench 1.1.0-651e7fd (using bundled LuaJIT 2.1.0-beta3) Dropping table 'sbtest1'... [root@localhost sysbench]#
Conclusion
The only intention of this blog is to help you learn how to install Sysbench 1.1 and benchmark MySQL, We have not tweaked MySQL for performance and the data collected with this exercise is not for publishing MySQL 5.7 performance benchmarking results.
The post Benchmarking MySQL 5.7 using Sysbench 1.1 appeared first on The WebScale Database Infrastructure Operations Experts.
