-// BenchmarkNewRewriterBuilder tests the cost of not caching the RewriterBuilder.
-// In current implementation, every call to NewWriter involves creating a RewriterBuilder.
-// Ideally, if multiple documents are to be processed at the same time, a RewriterBuilder
-// is created in advance and kept in memory, and Rewriter-s could be built from it.
-// This benchmark aims to find out the extent of its impact.
