 It's difficult to determine the exact threshold at which the slower execution speeds of interpreted regular expressions outweigh gains from their reduced startup time. It's also difficult to determine the threshold at which the slower startup times of source-generated or compiled regular expressions outweigh gains from their faster execution speeds. The thresholds depend on various factors, including the complexity of the regular expression and the specific data that it processes. To determine which regular expressions offer the best performance for your particular application scenario, you can use the <xref:System.Diagnostics.Stopwatch> class to compare their execution times.
 
-The following example compares the performance of compiled, source-generated, and interpreted regular expressions when reading the first 10 sentences and when reading all the sentences in the text of Theodore Dreiser's *The Financier*. As the output from the example shows, when only 10 calls are made to regular expression matching methods, an interpreted or source-generated regular expression offers better performance than a compiled regular expression. However, a compiled regular expression offers better performance when a large number of calls (in this case, over 13,000) are made.
