in a project we are using Plone 5 with Relstorage connected to an Oracle Database.
In our test environment we prepare the folder hierarchy, some objects, files and settings which are also needed on the production machine. Then we use
zodbconvert to convert the Relstorage to filestorage and blobstorage, create a docker image and start it on the production machine. When the docker is started the first time on an empty database
zodbconvert will be started to convert the filestorage and blobstorage back to Relstorage. But although the database is relatively small it lasts up to 24 hours to convert it back to Relstorage. In its output one can see that the speed is under 1 kB per second sometimes. I don't understand that behavior. How could I speed up this. The conversion from Relstorage to filestorage/blobstorage only needs a few minutes, but the other way around it is so damn slow.
At the moment I am using Relstorage in version 1.6.3.
