Re: [leshan-dev] Query regarding maximum device or client a leshan serve

[Frank Gerlach <Frank_Gerlach@xxxxxxxx>]

You could possibly create a dummy workload by running hundreds of wakaama client instances inside one or more beefy Linux boxes. 

Then maybe run a perl scripts (maybe also lots of instances of that) querying Leshan in order to measure response time.

The other approach would be to look into the code. For example, in wakaama, they use simple linked lists in order to find connections, objects, servers and so on. That does not scale well. (O(n) complexity with n the number of "things"). Which might not be a problem if wakaama just operates as a client on a small device.

I assume Leshan uses some sort of Hashtable for this, but I am not sure. Have a look at the code.

Also, please let us know about the results of your experiments/investigation. This is important information.

 Hi All,

I am able to up leshan server through the Jars provided by Lehsan and can perform the operations through UI of leshan Server. Able to discover the client through leshan jars and get the information of client on leshan server UI and Rest client.

Now, i am trying to connect lwm2m compliant device to leshan server. So, how many device leshan server can support to connect devices ?

Is there any scaling defined for leshan server?

I am following this link to perform task? :?https://github.com/eclipse/leshan

Thanks in advance for the help.

Best Regards,
Amandeep Singh Rattenpal
