[sysrepo-devel] sysrepo performance with large datastore

[Augello Marco]

Hi all,

we would use netopeer 2 for Italtel device configuration in cloud oriented applications

We are testing sysrepod performance for our scopes.

We noticed a significant performance degradation after the creation of thousands of data nodes.
We always adding data nodes without deleting the old ones.

It seems that the problem depends on the generation and the handling of the persistence file.
When datastore file is large, also a single add operation is slow and more data nodes we adding more slow is the operation.

For example, when the datastore is empty the first add is very fast, but after 4000 data nodes added, the next add takes 7 seconds and so on.

Have you notice of this degradation? Maybe is our wrong configuration (In attach there is the yang model that we are testing at this moment)?

Is in your roadmap an eventually change of the persistence handling? (different from single xml file)

tell me if you need any other information.

Thanks in advance,
Sorry for my English :)

Marco
