okay, so caches slow applications down? i suppose it can happen, but in general caches

deleting the spotlight "library" then waiting several hours for the index to
rebuild, on the uncertain prospect that it will save a few seconds -- great strategy
This argument would be true if all the above mechanisms were implemented 100%
correctly and suffered from no data rot or corruption problems. But the fact
is that it's easy to get a corrupt or inefficient Spotlight database that is
way slower than one that is freshly rebuilt; and after months (or sometimes
years) of use, it's worth deep-cleaning the system caches to get some boot
speed back.
my spotlight db's never been rebuilt; it's around a year old; searches
aren't slow; i'll rebuild it when i want (probably when things that
should be found aren't), and without paying $19
and the OS often clears caches during OS updates anyway, which is plenty
often enough for me; i rarely reboot, but if i did it a lot i'd most
certainly not clear caches regularly because it would make my boot times
_slower_
so i think these specific strategies are rarely needed individually, and
when they are truly needed is not something an average user can discern;
but my main point is that these tools are sold based on generating FUD,
and with encouragement to use all of the strategies at once whenever
people are not sure what to do, which will usually produce results
opposite of what Mainmenu claims
