The one thing Splunk has going for it over ES is the amount of resources it requires to work at scale.

I needed 12 ES boxes for every one Splunk box to handle the 100MB/day log load of my system, and even then they ran at a high load and searches often failed, and in some cases it took hours for the indexer to catch up.

This experience sounds especially bad. Sorry about that.

As mentioned in another comment in this post, I was doing 300gigs of data per day with an elasticsearch cluster size of 7 elasticsearch nodes (16 cores & 16gb ram per node) and load was around 5-10% cpu utilization.

100MB/day is pretty small in terms of log data, I think. If you attempt this again, please invoke the community (elasticsearch's is great!) and see if we can assist you in figuring out what's busted.
