The loading takes about that time
Elapsed time loading release file: 0.000127 seconds
(measured on Linux x86_64, jdk image with release file is on a slow filer, probably even faster in a good environment)
This is measured with clock



   // cache the release file of the JDK image
+  clock_t start, end;
+  double elapsed_time;
+
+  start = clock();
+
   os::read_image_release_file();
 
+  end = clock();
+  elapsed_time = ((double)(end - start)) / CLOCKS_PER_SEC;
+
+  if (log_is_enabled(Info, arguments)) {
+    printf("Elapsed time loading release file: %f seconds\n", elapsed_time);
+  }
