    copied!<p>This code tests indexing with Lucene.NET.</p> <pre><code>for (int i = 0; i &lt; 10; i++) { var stopwatch = Stopwatch.StartNew(); string indexPath = Path.Combine("C:\\lucene\\"); var directory = FSDirectory.Open(new DirectoryInfo(indexPath)); var analyzer = new StandardAnalyzer(LuceneConfiguration.Version); IndexWriter indexWriter = null; try { indexWriter = new IndexWriter(directory, analyzer, true, IndexWriter.MaxFieldLength.UNLIMITED); indexWriter.DeleteAll(); for (int documentNumber = 0; documentNumber &lt; 100; documentNumber++) { var document = new Document(); for (int fieldNumber = 0; fieldNumber &lt; 10; fieldNumber++) { document.Add(new Field("Field" + fieldNumber, "asdf qwerty Value" + fieldNumber, Field.Store.YES, Field.Index.ANALYZED)); } indexWriter.AddDocument(document); } indexWriter.Optimize(); } finally { if (indexWriter != null) { indexWriter.Close(); } } stopwatch.Stop(); Console.WriteLine("Index time: " + stopwatch.Elapsed.TotalMilliseconds); var reader = IndexReader.Open(directory, true); var searcher = new IndexSearcher(reader); var parser = new QueryParser(LuceneConfiguration.Version, "Field0", analyzer); var query = parser.Parse("asdf"); var collector = TopScoreDocCollector.create(10, true); searcher.Search(query, collector); Console.WriteLine("Hits: " + collector.GetTotalHits()); } Console.ReadKey(); </code></pre> <p>For each time the indexing is running, the indexing gets slower and slower. If I skip the search after the indexing, it doesn't get slower. This only occur when I start it with debugging. Not if I start it without debugging.</p> <p>What may cause this?</p>
