To further measure the performance of MongoDB, you can run the Yahoo Cloud Serving Benchmark .
YCSB is an open source project which provides the framework and common set of workloads to evaluate the performance of different “key-value” and “cloud” serving stores. Use the steps below to run YCSB to evaluate the performance of MongoDB running on 64-bit Arm machine.
To run YCSB, additional software packages are required.
Install the additional software:
sudo apt install -y maven make gcc
sudo yum check-update
sudo yum install python2
For Ubuntu 22.04 and 24.04, Python 2 is not available using the package manager.
You can install Python 2.7 using:
cd $HOME
wget https://www.python.org/ftp/python/2.7.18/Python-2.7.18.tgz
tar xvf Python-2.7.18.tgz
cd Python-2.7.18
./configure --enable-optimizations
make -j $nproc
sudo make altinstall
sudo ln -s /usr/local/bin/python2.7 /usr/local/bin/python
Download the latest released YCSB zip file and uncompress it.
cd $HOME
mkdir ycsb && cd ycsb
curl -O --location https://github.com/brianfrankcooper/YCSB/releases/download/0.17.0/ycsb-0.17.0.tar.gz
tar xfvz ycsb-0.17.0.tar.gz
Now cd into project folder and run the executable to print a description of how to use the benchmark.
cd ycsb-0.17.0
./bin/ycsb
To load and test the performance of loading data(INSERT) into default database ycsb at localhost:27017 where MongoDB is running using the synchronous driver run the following command:
./bin/ycsb load mongodb -s -P workloads/workloada -p mongodb.url=mongodb://localhost:27017/ycsb?w=0 -threads 10
The “-P” parameter is used to load property files. In this example, you used it load the workloada parameter file which sets the recordcount to 1000 in addition to other parameters. The “-threads” parameter indicates the number of threads and is set to 1 by default.
To test the performance of executing a workload which includes running UPDATE, Read Modify Write(RMW) and/or READ operations on the data using 10 threads for example, use the following command:
./bin/ycsb load mongodb -s -P workloads/workloada -p mongodb.url=mongodb://localhost:27017/ycsb?w=0
The workloads/workloada file in this example sets the following values readproportion=0.5 and updateproportion=0.5 which means there is an even split between the number of READ and UPDATE operations performed. You can change the type of operations and the splits by providing your own workload parameter file.
For more detailed information on all the parameters for running a workload refer to Running a Workload.
At the end of each test, statistics are printed to the console. Shown below is the output from the end of Load/Insert test
