Hi Oz
I live in Australia, and have ADSL2 internet (pretty standard for a lot of people here). My download speed at the absolute best (severely optimised file connection) is 1.6Mbps. My average speed for most everything is between 500-800kbps. My latency ranges from 220ish to over 300ms. (again pretty standard here).
I was away from SL for a few weeks due to illness, and prior to having to take time off I was a model and blogger...so had to be able to rez in quickly, and clearly.
On coming back to SL, I noticed my Firestorm was running very poorly.....texture load times, and mesh rez times were now abysmal. I contacted the Firestorm group, and was given a link to your blog about the changes made. Also given links to improve rez times. Rebooted PC, and modem just in case and then downloaded the latest official viewer (as suggested in this thread and on the blog).
Logged in at my home, and everything took ages to load, despite being on a platform in the air with very little around me. Figured that was most likely as it was a completely fresh login so things had to cache, I waited. Once that was finally done, I decided to head over to one of the worst shopping places for rez-times.......Collabor88. I arrived there at 1.43am SLT, and gave up at 2.25am SLT. At that point barely half the place was rezzed, and as can be seen from the photos here on Flickr things not only took quite a while to show, but the grey lasted well......until I gave up for some things. This was despite there being at most 4-5 others on the sim at any time.
I do not see the improvements you mention, in fact for me it is so much worse as to make SL pretty unplayable. I suspect that if there is high latency, and slow internet then the data just gets choked and barely trickles through.
PS: My son and I have no issues playing any other online game, even ArcheAge which is very demanding as it is to a certain extent user defined, and 85% client side. We also have no issues with streaming movies. So despite having "slow" internet, it is absolutely fast enough to do most everything we could want.
