> We should add a warning in the startup script for Linux, if the output of the following is below a certain threshold (maybe 300?). The warning could indicate that features like UUIDField, SSL etc. might not work properly (or be slow). As a hint, we could then suggest the user to configure a non blocking SecureRandom (SOLR-10338) or install rng-tools, haveged etc.
