These are not hardware specs.  They are software specs, and really don't
contain anything useful.  From this, we can tell that you are running
CentOS 7 64-bit with a 3.10 kernel, and that's pretty much it.

This log shows no errors.  It says that Jetty is listening on port
9999.  It does look like it took a couple of minutes for Solr to finish
starting, but other than that, I cannot see any problems here.

Troubleshooting performance issues like this requires careful
observation, and may be very difficult to do via a mailing list.  We
have pretty much zero information to go on, and the logs you have sent
do not even contain any relevant warnings.

There is only one odd thing.  The log jumps from 596 milliseconds to
127902 milliseconds -- over two minutes with absolutely no information
logged, after which it completes startup.  When I start a
freshly-downloaded Solr 6.2.1 in foreground mode, the time difference
between these two log entries on my system is only 32 milliseconds, and
then Solr is fully started less than a second later.

Do you have any more information you can share?  Something I'd like to
see is a screenshot of "top" running in your terminal, after starting
the fresh Solr with no collections.  Before getting the screenshot,
press shift-M to sort the list by memory usage.

Thanks,
Shawn
