I don't know what the CPU usage is like compared to LCF, but I use ICUFoldingFilterFactory instead. This does several things in one pass, including lowercasing (which it calls case folding), and it is aware of the all characters in Unicode. https://wiki.apache.org/solr/AnalyzersTokenizersTokenFilters#solr.ICUFoldingFilterFactory The ICU classes require additional jars to be loaded into Solr before they will work.
