The current dashboard of object store in horizon is very simple. it provides you a button to upload only one file at a time into the container. If you have many images to store into swift, you may need to try other tools, such as python-swiftclient which is a command line tool, e.g.swift upload

For the second question, Swift doesn't use updatedb.mlocate in my mind. it should be safe to disable it. Based on the TOP output, it seems that the CPU workload of container replicator and auditor are too high. Perhaps you need to tune the config file to decrease their workload. paste your config
