How efficient are my REST calls on WCSTags: support rest bottleneck performance mcduffs cse wcs troubleshooting
Using
RESTful
API
calls
during
page

is
becoming
the
norm
in
store

development.
It
enables
developers
to
isolate
the
front
end
from
the
multitude
of
backend
systems
that
might
provide

As
a
result
of
that
separation,
performance
might
degrade
due
to
the
