* leachers should see fast download rates as well.
* @author Christian Grothoff
*
- * Sample outputs:
- * - 1 MB, 3 peers:
- * Download speed of type `seeder 1' was 3864 KiB/s
- * Download speed of type `seeder 2' was 3764 KiB/s
- * Download speed of type `leach' was 3592 KiB/s
- * Analysis: download too small for trust to go into effect
- * - 100 MB, 3 peers:
- * Download speed of type `seeder 1' was 4018 KiB/s
- * Download speed of type `seeder 2' was 4016 KiB/s
- *
- * Analysis: leach squeezed out entirely early, then backs off far too
- * far => fails to ever recover (code needs improvement...)
- * [system load is initially very high, then drops to 0
- * after seeders are done]
+ * Sample output:
+ * - 10 MB, 3 peers, with delays:
+ * Download speed of type `seeder 1' was 757 KiB/s
+ * Download speed of type `seeder 2' was 613 KiB/s
+ * Download speed of type `leach` was 539 KiB/s
+ *
+ * - 10 MB, 3 peers, without delays:
+ * Download speed of type `seeder 1' was 1784 KiB/s
+ * Download speed of type `seeder 2' was 1604 KiB/s
+ * Download speed of type `leach` was 1384 KiB/s
