2016-05-29 Version 0.11 released

Simplifyworks team presents the 0.11 version of the Simplifyworks Core.

With the release of Simplifyworks Frameworks 0.9, we carried out two different stress tests. Our goal was to find out how would the application act under heavy load.

We tested Projects and Issues, with 10k, 20k, 50k, 100k, 200k and 500k records respectively. Filling the DB with records was averaging at 8 ms per record filled. The threads used for testing included 11 requests in the case of Projects and 14 requests for Issues. For the testing itself we used 100, 200, 300, 400, 500 and 600 threads over 60 seconds when testing Projects.

When testing Issues, the response times were slower with more records in the DB, so we used different numbers of threads: 100 – 500 for 10k and 20k records, 100 – 300 for 50k and 100k, 25 – 200 for 200k records and only 25 and 50 threads for 500k records, as the throughput was very low.

The values focused on while testing were:

• Average response time
• Standard deviation in response time
• Throughput
• Error rate

Results

Pleae keep in mind that the testing threads include 11 requests for Projects and 14 requests for Issues.

You can see result graphs for better comprehension of our results. The results in case of Projects were pretty much as expected. The average response time was mostly under 5 seconds when testing with 100 threads over 60 seconds (1100 requests) and slightly increasing with more threads involved. The throughput was not very much affected by the increase of threads, but the number of records in DB caused almost linear decrease in throughput.

In the case of Issues, the results are much more difficult to read, because with each Issue we store much more data than with Projects, so the application was less responsive with more records in DB. The relation between results, data stored and threads running was about the same as with Projects.

In both Projects and Issues, the error rate is closely connected with exceeding throughput (when the number of requests per second was greater than throughput, the requests were not getting responses, hence the errors).

2016-04-18 Version 0.8.1 released

With the end of our 21st sprint Simplifyworks team presents the 0.8.1 hotfix version of the Simplifyworks Core.

2016-03-17 Hands-on Workshops

Starting today we are running free courses in Hradec Králové for everyone who wants to use our framework.

Please contact us in case you want to learn something new in March. Terms of the workshops are

• Thursday, March 17
• Wednesday, March 23
• Tuesday, March 29

We will go through

• Intro to simplified development (What, When and Why)
• Architecture and technologies (backend, frontend, deployment, Java, JavaScript etc.)
• Setting up your boilerplate (downloading and using the frameworks)
• Example of use (sample module)
• Future plans and roadmap introduction

2015-08-27 Version 0.2.1 released

Simplifyworks team presents first publicly released version of the framework, which is 0.2.1.

You'll find some basic structures like users, persons, organizations and roles. We've also added basic workflow using the Activiti Engine (embedded) and we are very proud to announce using the Elasticsearch engine for not only storing fulltext data, but also for storing the privileges assigned to users and roles. So the privilege limited object access is as quick as it can be. You can download the framework core from our local repository

• simplifyworks-core-0.2.1.jar

2015-06-17 Getting started

Simplifyworks proudly presents this new website and our Twitter account. And at least but not last, we have a really nice logo, thanks to a talented pro Eva Veselá.
