Docker Import tool too slow

Hi, I am working with a dataset and a neo4j in docker, my computer is a VM in azure with ubuntu and 1T of disk and 128 gb of ram

the problem is that using the import tool alway become to slow at 70% of the node import process, I configured the verbose flag and it seem that get stuck at sort of the Prepare node index.

I already change the size of the heap but always get stuck at that point, doesn't matter if I reduce the number of files.
