Graphical representation of OLTP READ-WRITE transactions performance in TokuDB, RocksDB and InnoDB:
Conclusion
The results of benchmarking concluded RocksDB the most ideal candidate for SSD based storage infrastructure compared to InnoDB and TokuDB, The most compelling reasons for using RocksDB on SSD are performance, storage efficiency/compression and much smaller write amplification compared to InnoDB or TokuDB.
The post Comparing TokuDB, RocksDB and InnoDB Performance on Intel(R) Xeon(R) Gold 6140 CPU appeared first on The WebScale Database Infrastructure Operations Experts.

“time elapsed” is the variable we seriously look for to measure CPU performance, In this case it is 174.1418 seconds.
Benchmarking threads performance using sysbench
When we increase the threads workload, each worker thread will be allocated a mutex (a sort of lock) and will, for each execution, loop a number of times (documented as the number of yields) in which it takes the lock, yields (meaning it asks the scheduler to stop itself from running and put it back and the end of the runqueue) and then, when it is scheduled again for execution, unlock.

Threads fairness:

To conclude the interpretation of thread performance benchmarking, we annotate time elapsed (actual time for the completion of the activity), in this case it “60.0003” seconds.
Benchmarking mutex workload
When benchmarking mutex workload, sysbench will run a single request per thread. This request generates load on the CPU (using a simple incremental loop, through the –mutex-loops parameter), after that it makes a random mutex, increments a global variable and release the lock again. This process is continued till the number of locks mentioned (–mutex-locks). The random mutex is generated by –mutex-num parameter.
[root@localhost shiv]# sysbench --test=mutex --num-threads=130 run

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)

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

Benchmarking CPU with just 1 thread , we look for time elapsed value majorly (In this case it is 10.0457s)
[root@localhost sysbench]# sysbench --test=cpu --cpu-max-prime=300000 run
sysbench 1.1.0-651e7fd (using bundled LuaJIT 2.1.0-beta3)
Running the test with following options:
Number of threads: 1
Initializing random number generator from current time
Prime numbers limit: 300000
Initializing worker threads...
Threads started!

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.

Initializing worker threads...
Threads started!
Throughput:
read: IOPS=2111.56 32.99 MiB/s (34.60 MB/s)
write: IOPS=1407.37 21.99 MiB/s (23.06 MB/s)
fsync: IOPS=4500.34
Latency (ms):
min: 0.00
avg: 1.99
max: 621.12
95th percentile: 4.10
sum: 159899.55
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 ***************************

Rows: 1921969
Avg_row_length: 233
Data_length: 449724416
Max_data_length: 0
Index_length: 0
Data_free: 5242880
Auto_increment: 2000001

Comment:

ERROR:
No query specified
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:
queries performed:
read: 28214
write: 0
other: 0
total: 28214
transactions: 28214 (2799.30 per sec.)
queries: 28214 (2799.30 per sec.)
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.
