     The possible scheduler types are:
  +
-    **KIST**: Kernel Informed Socket Transport. Tor will use the kernel tcp
-    information stack per-socket to make an informed decision on if it should
-    send or not the data. As implemented, KIST will only work on Linux kernel
-    version 2.6.39 or higher.
+    **KIST**: Kernel-Informed Socket Transport. Tor will use TCP information
+    from the kernel to make informed decisions regarding how much data to send
+    and when to send it. KIST also handles traffic in batches (see
+    KISTSchedRunInterval) in order to improve traffic prioritization decisions.
+    As implemented, KIST will only work on Linux kernel version 2.6.39 or
+    higher.
  +
-    **KISTLite**: Same as KIST but without kernel support which means that tor
-    will use all the same mecanics as KIST but without the TCP information the
-    kernel can provide. KISTLite will work on all kernels and operating
-    systems.
+    **KISTLite**: Same as KIST but without kernel support. Tor will use all
+    the same mechanics as with KIST, including the batching, but its decisions
+    regarding how much data to send will not be as good. KISTLite will work on
+    all kernels and operating systems, and the majority of the benefits of KIST
+    are still realized with KISTLite.
  +
-    **Vanilla**: The scheduler that tor has always used that is do as much as
-    possible or AMAP. Vanilla will work on all kernels and operating systems.
+    **Vanilla**: The scheduler that Tor used before KIST was implemented. It
+    sends as much data as possible, as soon as possible. Vanilla will work on
+    all kernels and operating systems.

     msec. Maximum possible value is 100 msec. (Default: 0 msec)
