Apache OFBiz 13.07 Load Testing Results (1,000 OPD)

Ashish VijaywargiyaPublished: Updated:

In a recent blog post we explored Apache OFBiz Performance Benchmarking. Since then we have executed Apache OFBiz 13.07 load testing. Today’s tech update  looks at how performance benchmarking can support the load testing process, and reviews both our testing processes and test results.

Q. Why is OFBiz 13.07 load testing important?

pressure gauge--Apache OFBiz 13.07 load testing--how does it measure up?Load testing is an effective means of assessing the performance of an E-commerce/ERP solution. Key purposes of OFBiz 13.07 load testing include:

  • To  to benchmark Apache OFBiz 13.07 against industry performance standards
  • To help the user evaluate the suitability of the system configuration and the logical architecture
  • To help the user evaluate the overall robustness of the codes/system
  • To check the threshold capacity of the E-commerce system
  • To determine what sort of load increase will push the hardware configuration to its limits
  • To help the user estimate the minimal hardware configuration that should be able to manage the same load
Q. Which OFBiz 13.07 load testing process did HotWax utilize?

While the process outlined below could be used to test nearly any E-Commerce /ERP solution, our OFBiz 13.07 Load Testing process involved: 50,000 visits for a typical E-Commerce business doing 1,000 orders a day at 2% conversion rate.

Q. Which performance processes were tested?

Apache OFBiz 13.07 load testingIn performance testing, it is important to identify  processes that are useful to test and which are key to the E-commerce cycle. (For our OFBiz 13.07 load testing, we followed OFBiz business processes and use case artifacts as outlined on the official Apache website for OFBiz Wiki.) Today’s tech update includes a detailed analysis of these use cases along with the JMeter test plans and instructions. Additional details are available here:

Q.Which parameters were selected?

The OFBiz 13.07 load testing parameters we used  (listed below) are the same ones noted in a previous performance benchmarking blog. We included key parameters that can affect system performance and that that mirrored the actual production system usage:

  • Registered customers
  • Anonymous customers
  • Administrative users
  • User concurrency
  • Key user transactions and their frequency
  • User growth
  • Peak and off-peak time periods
  • Normal business hours
  • Conversion rate (percentage of customers completing order process)
Q. What were the user count totals?

Total user counts in each use case for running 24 hrs test plan were as follows:

Use Case NameUser counts
Product search50000 visits
Order by anonymous user
Order by registered user
Order by phone channel
450 orders
450 orders
100 orders
Picking process1
Packing and shipping process1
Bulk receive inventory1

Note: The exact number of fulfilled orders would vary depending on the picklist and availability. For our test purposes, a  single user executes the pick-pack process and orders are filled one-by-one.

Q. What technical architecture was used?

For our OFBiz 13.07 load testing process, we used logical architecture for  a single machine multiple user configuration with splitting async and sync jobs over two OFBiz instances (as outlined in previous tutorial blog posts). Our load test simulated a server running an E-commerce store receiving 1,000 OPD with a 2% conversion rate. We executed Apache OFBiz 13.07 load testing within both a hypothetical and an actual technical environment in regard to the following parameters:

  • CPU Idle: A computer processor is described as idle when it is not being used by any program.
  • CPU Usage: CPU usage can be monitored to see how much of the processor’s capacity is in use.
  • Disk I/O: Disk I/O encompasses the input/output operations on a physical disk. The total number of individual disk IO requests completed over a period of one minute
  • Bits I/O: The total number of bits sent to the disk (write) and retrieved from the disk (read) over a period of one second
  • Load Average: The system load is a measure of the amount of computational work that a computer system performs. The load average represents the average system load over a period of time. It conventionally appears in the form of three numbers which represent the system load during the last one-, five-, and fifteen-minute periods.

Did Apache OFBiz 13.07 measure up?

blue question markThe short answer is yes.  After executing OFBiz 13.07 load testing as described above, our assessment is that it is a robust and full-featured E-commerce/ERP system with excellent end-to-end functionality. For detailed results, please refer to the charts and graphs shown below.

Detailed Load Testing Results

Below are the Hyperic reports detailing the execution of the use cases for 24 hours:

CPU Usage
load test cpu-usage   
The CPU usage graph shows that it is using a minimum of 20% and a maximum of 32% of CPU capacity during the test. This indicates that the performance of the server with a 1,000 OPD load is satisfactory. The server can facilitate an additional load during the peak season or peak time.

Here the CPU usage seems less, so it would be logical to wonder why we did not use a machine with a lower configuration such as 1CPU. The reason behind this was to keep  the value of all other key performance key parameters in within standard range.

Load Average 5 Minutes
load test- 5 min avg
The value of Load Average lies between 0.25 and 0.65. This is also a satisfactory result, it should be in between 0.0 – 1.0  range as standard, so a reading below 0.70 means it is working well. In fact, the  system is capable of taking an additional load of up to 25% more during peak time.

Free Memory
 load testing- free memory
The above graph shows how much memory was free during the 24-hour period of the test. The memory used was between 1.6G and 2.5G out of total available 3.8G RAM. There is buffer of  an additional (approximately) 1G of RAM available during peak time. The results are quite satisfactory here as well.

Disk Writes Per Minute
load test--disk writes
Here we see that disk utilization is satisfactory, and also there is plenty of  bandwidth to perform at an  additional 20-25% load during peak time.
