Your points on speed of MS applications, in particular start times and
general responsiveness, are valid but do you understand how MS is doing
this or what costs are involved?
I suggest you read up on PGO (Profile Guided Optimization) and do a ton
of work disassembling some of these supposedly "fast" applications
before posturing that their illusion of "speed" is actually a good
thing. Yes, the form of optimization used does shorten access times and
code paths for the "most used" features but it comes at a significant
As soon as a user does something with the application that is not
"standard" (i.e. something that was sacrificed to enable the supposed
"speed" on more common usage), the illusion of speed disappears. In
other words, those who choose to use an application in particular but
common ways are rewarded with a "boost" in speed. Unfortunately, other
users who need to work in non-standard ways are punished with a
"slow-down" for not following the rest of the herd.
Who gets to decide standard usage, or better said rewards and
punishments, for the operation of open source programs?
Though I've seen no work on the security issues caused by PGO, the
method it uses, namely cutting assembly sub-routines into chunks and
then rearranging the chunks based on usage (including mixing chunks from
various sub-routines), makes debugging and security auditing of binaries
a major pain in the ass.
For the end user who cares nothing about security or reliability, PGO
and other "speed" tricks are a Good Thing (tm) but it requires owning
the source to the OS to keep the tricks keep working. It also requires
significantly more development, testing and debugging time. If you've
got money to burn (as Microsoft does), keeping the illusion of speed for
your products is worth the costs.
Can you name any open source operating system or application so well
funded it has time/money to burn?
Speed tricks are all fun and well for end users but they come at a
serious cost to those who write, test, debug and maintain the code. If
you think the illusion of speed on common usage is actually worth the
effort and cost, they you should start working on it or paying someone
to work on it rather than just complaining about the greater patience
level of those who actually understand both the whole situation and the
