Manticore 2.7.5 vs Sphinx 3.1.1

Hi Here we benchmarked Sphinx 3.0.2 vs Manticore 2.6.2. This was 8 months ago and both Manticore and Sphinx changed since then. As it’s said in Sphinx 3.0.3 announcement Sphinx 3.0.3 is up to 2x faster compared to 3.0.2, so it’s interesting to do another benchmark. This time let’s test on a real dataset – Hacker News comments. The benchmark was conducted with the following conditions: […]

Percolate queries: Manticore Search vs Luwak

In this article we test how percolate queries perform in Manticore Search and Luwak.

Introduction

Recently we tested the performance of Percolate Queries in Manticore Search and Elasticsearch. Today we are looking at Luwak, a stored query engine based on Lucene search library. When we developed Percolate Queries […]

Research on Jemalloc

As said on http://jemalloc.net/:
jemalloc is a general purpose malloc(3) implementation that emphasizes fragmentation avoidance and scalable concurrency support.
Some Sphinx and Manticore Search users prefer jemalloc over malloc and say it allows to save some RAM. I’ve tested how jemalloc affects resource consumption and response time for 2 weeks on 3 Manticore clusters (se03/03-2, se04/04-2, se05/05-2) each of which: […]

Free config review

There are often optimizations that can be made to a Sphinx / Manticore setup by changing some simple directives in the configuration or making quick changes to an index definition.

Some common mistakes and issues can include:

  • doing main+delta without kill-lists, even if the delta does include updated records found in the main
  • using wildcarding with very short prefix/infix which can hammer performance in some cases
  • disabled (unintentional) seamless rotates and getting stalls on index rotations
  • adding texts as string attributes even if they are not using for any kind of operation (filtering, grouping, sorting) or mandatory to be present in results
  • using deprecated settings 

Having a quick look on the configuration can show issues or potential issues, this is why we want to offer a gift to our growing community!

When uploading your configuration file, we recommend to remove any database credentials first.

We suggest also you give as many possible details about your setup: how big is the data you have, how typical queries look and what issues you experience.
