Lots of times we could see different benchmarks performed by tpcc-mysql. So today I want to tell you about how to use tpcc-mysql and how to build graphs with gnuplot in a few easy steps.
As an example I’ll compare Percona Server 5.5 (latest version: 5.5.31) performance by changing InnoDB buffer pool size: innodb_buffer_pool_size = 256M / innodb_buffer_pool_size = 768M on my old test machine
System Info
- CPU: Intel(R) Pentium(R) 4 CPU 1.80GHz
- MemTotal: 1543732 kB
- OS: LinuxMint 15 (based on Ubuntu 13.04)
Files
You can find the source code of all files at the end of this post
Installation
- Install latest Percona Server
- Install tpcc-mysql
sudo apt-get install bzr
bzr branch lp:~percona-dev/perconatools/tpcc-mysql
make all
In this case it’s installed to ~/tpcc-mysql/ directory
- Install gnuplot
sudo apt-get install gnuplot
DB Config
First test will be running with innodb_buffer_pool_size = 256M option enabled and second one with innodb_buffer_pool_size = 768M
Test for innodb_buffer_pool_size = 256M
Create DB
Assuming that Percona Server 5.5.31 installed and configured
cd ~/tpcc-mysql
mysql -u root -p -e "CREATE DATABASE tpcc1000;"
mysql -u root -p tpcc1000 < create_table.sql
mysql -u root -p tpcc1000 < add_fkey_idx.sql
Load Data
./tpcc_load 127.0.0.1 tpcc1000 root "root-password" 20
Where:
- Host: 127.0.0.1
- DB: tpcc1000
- User: root
- Password: root-password
- Warehouse: 20
...DATA LOADING COMPLETED SUCCESSFULLY.
In this case DB size is 1.9GB
Run tpcc-mysql test
./tpcc_start -h127.0.0.1 -dtpcc1000 -uroot -p -w20 -c16 -r10 -l1200 > ~/tpcc-output-ps-55-bpool-256.log
Where:
- Host: 127.0.0.1
- DB: tpcc1000
- User: root
- Warehouse: 20
- Connection: 16
- Rampup time: 10 (sec)
- Measure: 1200 (sec)
The most interesting part in the output is:
MEASURING START.
10, 25(17):9.005|9.221, 21(0):1.866|1.869, 3(0):0.647|0.840, 1(0):0.000|10.614, 2(2):19.999|29.490
20, 22(14):9.419|9.555, 26(0):1.591|1.593, 2(0):0.593|0.788, 4(0):10.453|10.688, 3(3):19.999|22.962
30, 41(32):8.703|9.057, 32(0):1.615|1.662, 3(0):0.588|0.777, 2(0):9.530|10.495, 3(2):19.999|22.983
The first two values are “time range” and “transactions”, so you can read it as:
0-10 sec, 25 transactions
10-20 sec, 22 transactions
20-30 sec, 41 transactions
Test for innodb_buffer_pool_size = 768M
Repeat following steps for innodb_buffer_pool_size = 768M (change it in my.cnf) and get results:
- DB Config
- Create DB
- Load Data
- Run tpcc-mysql test
./tpcc_start -h127.0.0.1 -dtpcc1000 -uroot -p -w20 -c16 -r10 -l1200 > ~/tpcc-output-ps-55-bpool-768.log
There are 2 files: tpcc-output-ps-55-bpool-256.log and tpcc-output-ps-55-bpool-768.log which have benchmarking results for both tests.
Generate data file for each test
./tpcc-output-analyze.sh ~/tpcc-output-ps-55-bpool-256.log > tpcc-256-data.txt
./tpcc-output-analyze.sh ~/tpcc-output-ps-55-bpool-768.log > tpcc-768-data.txt
Merge data files
paste tpcc-256-data.txt tpcc-768-data.txt > tpcc-graph-data.txt
Build graph
./tpcc-graph-build.sh tpcc-graph-data.txt tpcc-graph.jpg
In this case tpcc-graph-data.txt is a filename of source datafile and tpcc-graph.jpg filename of graph which will be generated
Graph ready: tpcc-graph.jpg
Note: “using 3:4 … with lines axes x1y1” in tpcc-graph-build.sh means that columns number 3 and 4 in datafile will be used for as axises x and y accordingly while building second line
File listing
tpcc-output-analyze.sh (I got it there and a bit modified)
TIMESLOT=1
if [ -n “$2” ]
then
TIMESLOT=$2
echo “Defined $2″
ficat $1 | grep -v HY000 | grep -v payment | grep -v neword | awk -v timeslot=$TIMESLOT ‘ BEGIN { FS=”[,():]”; s=0; cntr=0; aggr=0 } /MEASURING START/ { s=1} /STOPPING THREADS/ {s=0} /0/ { if (s==1) { cntr++; aggr+=$2; } if ( cntr==timeslot ) { printf (“%d %3dn”,$1,(aggr/’$TIMESLOT’)) ; cntr=0; aggr=0 } } ‘
tpcc-graph-build.sh
#!/bin/bash
### goto user homedir and remove previous file
rm -f ‘$2’gnuplot << EOP
### set data source file
datafile = ‘$1’### set graph type and size
set terminal jpeg size 640,480### set titles
set grid x y
set xlabel “Time (sec)”
set ylabel “Transactions”### set output filename
set output ‘$2’### build graph
# plot datafile with lines
plot datafile title “PS 5.5.1, buffer pool: 256M” with lines,
datafile using 3:4 title “PS 5.5.1, buffer pool: 768M” with lines axes x1y1EOP
Great article Michael. Thank you for sharing.
There is a little problem in analyze file.
printf (“%d =
”,$1,(aggr/’$TIMESLOT’)) ;
should be changed to:
printf (“%d =
”,$0,(aggr/’$TIMESLOT’)) ;
In case of awk with field separator (FS) $1 means a first field of input record so this is exactly what I was looking for and it works just like needed. Is that not a true?
Oh, you were right, yesterday I had a careless mistake in the test. 🙁
Sure, not problem 😉
Thanks for your interest!
Will tpcc-mysql be available in your Yum Repository sometime soon?
Stefan, I’m not sure about these kind of plans, but I’ll check that with our team.

Is it possible to close the foreign key checking?
I want to use this tool to test my sharding cluster, which does not support foreign key.
Adam,
The tool does not perform any actual checking, you can use it as is.
Hello,
I couldn’t find a documentation of the output of tpcc-mysql anywhere 🙁
Can somebody explain the output?
For example:
10, trx: 12920, 95%: 9.483, 99%: 18.738, max_rt: 213.169, 12919|98.778, 1292|101.096, 1293|443.955, 1293|670.842
20, trx: 12666, 95%: 7.074, 99%: 15.578, max_rt: 53.733, 12668|50.420, 1267|35.846, 1266|58.292, 1267|37.421
30, trx: 13269, 95%: 6.806, 99%: 13.126, max_rt: 41.425, 13267|27.968, 1327|32.242, 1327|40.529, 1327|29.580

50, trx: 12573, 95%: 7.185, 99%: 14.624, max_rt: 48.607, 12573|45.345, 1258|41.104, 1258|54.022, 1257|26.626
Thanks

Having some difficulties to build. When I do “make all”, I got this:
cc load.o support.o
mysql_config --libs_r
-lrt -o ../tpcc_loadload.o: In function
main':

collect2: error: ld returned 1 exit status
Makefile:27: recipe for target ‘../tpcc_load’ failed

Am I doing somethin wrong here?
