I was on PURE100 for the pass 2 years and I didn't have any major issues with MR, there were some disconnections, crawling speed, etc but they were minor issues that happen maybe once a month, come and gone quickly. I didn't trouble accessing China sites and Twitch was streaming at source smoothly--I don't use Twitch actually, just tested it cause someone kept complaining, I had tested PURE with VQ concurrently. although VQ was more stable for Twitch, the difference was very minor. all in all, I was please with PURE100.
After upgraded to 1Gbps, everyday browsing and P2P was as good and better for utorrent, I could do over 20MBps per torrent, not that I need that speed cause I always more concern about the data I owe to the others. One of the main reason I upgraded is because I need higher upload as PURE only allow 50Mbps, the other is MEGA which I upload frequently to share my videos--
NOT pirated hollywood movie or PORN as some VQ supporter was trying to accused me when I proved to them that VQ has lower upload speed to MEGA as compare to MR PURE. the 1Gbps upload is better, needless to say but unfortunately, the upload to MEGA had drop to VQ level! my wild guess is MR is throttling the upload cause the speed will drop from ~1.2MBps to ~500KBps after 1 minute without fail! or maybe the NC has bigger pipe to MEGA compare to MR's own network. for this alone, I kind of hope I didn't upgraded...
TL;DR, just my whining, MR 1Gbps does able to sustain close to 100
MBps of download, at least locally.
5GB done in less than 1.5 minute or 55MBps average. you don't need what SSD or high end whatever BS from the other saleperson had claimed.
