With a 5x limit, you could serve 50 requests per second. This frees up connections to handle search traffic. Keep in mind that both searches and updates count as concurrent connections, so if you have 5 workers sending updates and a user submits a search, something will fail with an HTTP 429. This allows you to send searches to your replica and updates to your primary. When performing a bulk reindex, update operations should send documents in batches of between 100 and 1,000 per request, from one or two indexing processes. High volumes of search traffic can also benefit from a layer of caching on the application side. ./cache/docs-websolr-com-2002.html ./txt/docs-websolr-com-2002.txt
