However, when the system is restored, any applications
that need their inactive pages must reload them from swap
space, which will slow down the application’s first use after
system restart. Even so, the load time for a single application’s
inactive pages is substantially less than the wait for
a full system resume, and the consumer is more likely to
find it acceptable. Moreover, a background process could
restore the active pages from swap while the consumer is
using the system; preloading the saved applications speeds
up subsequent use.
