Measuring Speed

[Marcus]

I created a basic search on both my slow test board with stock xenforo as well as the live board with elasticsearch and a much faster computer, and the results are around the same.

How do you measure the speed of this search engine? And how do you optimize elasticsearch?

What query are you using to test? The more complex the query, the slower the default MySQL FULLTEXT search is going to be.

Also, how many posts are in your database?

I have more than one million posts, and the query was very basic like "house". I was just surprised that the elasticsearch query did take some time, maybe because of the general overhead.

Did you allocate enough memory to Elastic Search? If it's using disk as a RAM swap, it's going to be pretty slow.

I'll dig into it, I guess I gave it like 3 GB but I am not sure.

How much time?

Remember that ElasticSearch is used to narrow down the results and those results are then given to MySQL for a final query.
