-LLD is much faster than the GNU linkers for large programs. That's
-fast for small programs too, but because the link time is short
-anyway, the difference is not very noticeable in that case.
+E5-2680 2.80 GHz machine with an SSD drive. We ran gold and lld with
+or without multi-threading support. To disable multi-threading, we
+added ``-no-threads'' to the command lines.

+As you can see, lld is significantly faster than GNU linkers.
 Note that this is just a benchmark result of our environment.
 Depending on number of available cores, available amount of memory or
 disk latency/throughput, your results may vary.

-.. [1] With the ``--threads`` option to enable multi-threading support.

-.. [2] Since GNU ld doesn't support the ``-icf=all`` option, we
-       removed that from the command line for GNU ld. GNU ld would be
-       slower than this if it had that option support. For gold and
-       LLD, we use ``-icf=all``.
