Also other applications scale well on Windows. Why would Solr be different? The Solr page does not say about any performance limits on windows (shouldn't they say that upfront in that case!) https://lucene.apache.org/solr/guide/6_6/installing-solr.html#got-java (You can install Solr in any system where a suitable Java Runtime Environment (JRE) is available, as detailed below. Currently this includes Linux, OS X, and Microsoft Windows.) > Windows has very different handling for threads, memory, and files compared to Unix.
