CPI speed and storage speed will barely make any difference compared with download speeds though.

This completely depends on your DL cap, CPU and Storage speeds. On an older 5400rpm laptop HDD the verification process is REALLY slow.

Just to prove this, I did a run of same files on same hardware except now on a HDD.

"Patch Tuesday" is traditionally the second Tuesday of the month, ie April 10th ....

Traditional Patch Tuesday apparently no longer applies....Updates have been and will be released at any time.

I stand corrected but tbh your figures are decidely skewed because you have very fast broadband. For users with a more sedate download speed, the %differential will be a lot less.

Yes, that is true. The slower the broadband speed the less impact other hardware has on total completion times.

My internet is slow, I need to upgrade it soon.

Agreed, Patch Tuesday really only applies to standard updates, and even then MS have bought out cumulative updates more frequently now and then.

MS stated a long time ago Patch Tuesday no longer exists as a rigid barrier. It is just merely convenient to plan for target dates as part of a business plan - most companies plan short term on a monthly cycle.

There is a sound reason to use Tuesdays though. Often last minute work is done by techies over weekend, and Monday is needed to get management approval to issue release.

Well, I have just tested it and obviously the above is obvious EXCEPT.........

It was trundling along at a reasonable 8ish MB/s (more or less my top speed) and then just died to 2.8 MB/s making it much slower. Back to good old write buffers on hard drives I guess?

So you are right i.e.an ssd will be much faster than an HDD, but in the end, still much faster than normal Windows download speeds.

The download speed is the same in WU, but it's all the other copying and integrity verification stuff that takes ages on WU.

On every release of a new build, the download part of WU has been way less than 2 minutes for me, but the total time taken to complete the online part of WU, has been about 20-40 minutes...depending on update.

Oh, almost forgot, the integrity checks on WU are single threaded, while I believe it's multi threaded in UUP-Dump (need to verify this, but at least it verifies multiple files at the same time), or just a different type of integrity check.

All I know with an SSD, it downloads at a flat 8 MB/s until finished, with an HDD it drops after a shortish period. My hard drive will write at 80 MB/s, so it cannot be a hard drive bottleneck, the CPU is the same of course. It would be great if we could run uupdump without verifying.
