We require an Elastic Search expert to help us identify and resolve performance issues we are having with our 5.4.2 installation. We are seeing various bottlenecks with our installation and require someone that can identify cause and solution.
The installation is on an Ubuntu server and all works without issues but performance at times drops considerably for no apparent reason. We are using ES for our Magento store and at times we see the CPU on the server spike to 100% causing an increase in query response times to 10sec from sub-second where it is usually.
There are 2-3 third party extensions in the installation as well (specific for local language support).
The individual will be given access to production systems, analytics and an internal resource to work with.
