Scalability and performance of Thingworx

Scalability and performance of Thingworx

Dear experts,

How would the performance of Thingworx be affected when it deals with huge amount of data and large number of transactions?

As per this blog performance of neo4j is hit once data size increases upto 50GB.

https://community.thingworx.com/community/developers/blog/2015/12/01/integrating-dse-cassandra​  so it advises to implement DSE.

When would system performance start getting a hit with DSE? How would system behave with say 250GB of data and 100M transactions per month ?

Is there any other way to support system in such cases?

Is there any test data or experimental results for such cases?

Re: Scalability and performance of Thingworx

Hello,

Thanks for the reply.

I'm currently evaluating different options. I'm also exploring a hybrid model with multiple persistence providers. That can combine PostGres and DSE.

What sort of challenges might be there in such case ?

Can you share any case study or success story or any use case that you might have seen?

Re: Scalability and performance of Thingworx

Hi Aanjan,

Thanks for the information. It is highly detailed and very useful.

However there are few points that I need better understanding of

1) '# Platform Requests/Sec' -- do this imply number of read requests or combination of read and write requests?

2) In the above table RAM size is not mentioned. How does RAM size affect the above data ?

3) Is there any particular reason why platform is much better able to handle WS requests rather than HTTP requests?

4) Also its clear that core size severely affects the performance. Is there any document or matrix that explains how to choose server size?



Re: Scalability and performance of Thingworx

We typically test on AWS instances with anywhere from 15 to 30 GB of memory. The most common tests seem to be on m3.2xlarge instances, and there are additional tests I'm seeing performed on the c4.2xlarge instances.

We have a Compatibility Matrix available under our support references documents:http://support.ptc.com/WCMS/files/166015/en/ThingWorx_System_Requirements_and_Compatibility_Matrix.p...

This goes over the minimum hardware considerations when choosing a server.

Hi Meghan,

It seems I do not have authorization to view the document. Is there any other way I can view it?

Re: Scalability and performance of Thingworx

Siddharth, do you have access to the eSupport Portal? The same document should be available under the 'Reference Documents' section.

Re: Scalability and performance of Thingworx

Hello Siddharth,

I sent you an email directly regarding how you should be able to access our eSupport portal.  If you haven't received it, please let me know.

Best,

I do have access to eSupport portal, but not to Refernce Documents.

Though I've upgraded the account, I'm not able to view it.
