Certainly. but that's because of the customer-facing workflow. It has
nothing to do with the specific back end implementation.
To take a silly hypothetical: If you suddenly replaced the entire
download/pkgadd/pkg delete mechanism with dpkg/apt-get behind the
scenes, it wouldnt matter to the customers, so long as the front end
remained the same and performed approximately the same.
However.. moving on...
We continue to look for performance wins in IPS. However, we feel that
improving the available automation and reducing the amount of human
effort required to manage a Solaris instance is of far greater import
to our customers than optimizing for a single, seldom performed task
that happens to be easily micro-benchmarked.
A fair conclusion in and of itself. However, in addition to pure speed,
the current implementation can lead to difficulties in debugging
performance problems with the package flow. As I've just had to deal
with for the last few weeks.
So my point is, if there arent truely significant gains, simpler is better.
And/or... it could be beneficial to customers if you would provide an
option (config or commandline, doesnt matter) to force single connection
downloads when desired.
