The comment on the change is:
Added note on Solid State Drives

------------------------------------------------------------------------------
   Remote filesystems are typically quite a bit slower for searching.  If the index must be
remote, try to mount the remote filesystem as a "readonly" mount.  In some cases this could
improve performance.
  
   * '''Get faster hardware, especially a faster IO system.'''
+ 
+  Flash-based Solid State Drives works very well for Lucene searches. As seek-times for SSD's
are about 100 times faster than traditional platter-based harddrives, the usual penalty for
seeking is virtually eliminated. This means that SSD-equipped machines need less RAM for file
caching and that searchers require less warm-up time before they respond quickly.
  
   * '''Add RAM to your hardware and/or increase the heap size for the JVM.'''
