  Some trivial QBenchmark stuff tells
  
    QBENCHMARK {
              m_repo->definitionForFileName(QLatin1String("ksldjfklsdjfkl.c"));
              m_repo->definitionForFileName(QLatin1String("ksldjfklsdjfkl.sdfdsf"));
              m_repo->definitionForFileName(QLatin1String("ksldjfklsdjfkl.ada"));
              m_repo->definitionForFileName(QLatin1String("12323.cklsjdf"));
              m_repo->definitionForFileName(QLatin1String("ksldjfklsdjfkl.c"));
              m_repo->definitionForFileName(QLatin1String("ksldjfklsdjfkl.sdfdsf"));
              m_repo->definitionForFileName(QLatin1String("ksldjfklsdjfkl.ada"));
              m_repo->definitionForFileName(QLatin1String("12323.cklsjdf"));
              m_repo->definitionForFileName(QLatin1String("ksldjfklsdjfkl.c"));
              m_repo->definitionForFileName(QLatin1String("ksldjfklsdjfkl.sdfdsf"));
              m_repo->definitionForFileName(QLatin1String("ksldjfklsdjfkl.ada"));
              m_repo->definitionForFileName(QLatin1String("12323.cklsjdf"));

              m_repo->definitionForFileName(QLatin1String("ksldjfklsdjfkl.sdfdsf"));
              m_repo->definitionForFileName(QLatin1String("ksldjfklsdjfkl.ada"));
              m_repo->definitionForFileName(QLatin1String("12323.cklsjdf"));

              m_repo->definitionForFileName(QLatin1String("12323.cklsjdf"));
              m_repo->definitionForFileName(QLatin1String("ksldjfklsdjfkl.c"));
              m_repo->definitionForFileName(QLatin1String("ksldjfklsdjfkl.sdfdsf"));
              m_repo->definitionForFileName(QLatin1String("ksldjfklsdjfkl.ada"));
              m_repo->definitionForFileName(QLatin1String("12323.cklsjdf"));
          }
  
  tells:
  
  new: between 4 and 5 msecs per iteration
  old: between 5 and 6 msecs per iteration
  
  I think the main issue in the "very old code" was, that we did a QRegExp per extension, not a combined one.
