A review of ADSL download times inside New Zealand reveal major improvements across four ISPs during 2013 (Chart 6).
In contrast, Latency to the USA is trending up, with the time it takes for data to be returned to TrueNet's test probes increasing significantly over the last three months.
Telecom VDSL is now the best performing VDSL provider.
Ultra Fast Broadband using fibre technology show speeds far superior to any other technology.
Vodafone Cable had the shortest Webpage Download times from the TrueNet test pages. On live pages, Orcon fibre is the best.
International Latency has increased significantly from last month, with results across all technologies showing increases reaching over 200 milliseconds.
Fibre Speed results are consistently faster than other access technologies although, for the first time, congestion is apparent on the 100Mb/s service for Orcon and Snap.
Testpage download times show Cable and Fibre results to be faster than DSL, but the Cable 100Mb/s service has considerable variation in average speed.
Latency is generally better with smaller ISPs and faster access technologies.
Domain Name Server (DNS) response times show a trending result with Fibre ahead of the rest, although one ISP can deliver DNS over ADSL with the same performance as Fibre.
Mid August TrueNet's file located on Trademe servers disappeared. We recovered by creating a dual file system in Auckland and Wellington, but that meant our data was limited to half a month. DSL performance normally varies from test to test, so the outcome of a shortfall in data meant that we had insufficient probe results for reporting ADSL or VDSL accurately alone, so for August we have combined the VDSL results with ADSL.
In this issue of the TrueNet Broadband Report we measure DNS response for the first time, and Snap takes the honours in the first round. Latency tests are extended to Australia.
Telecom still has some work to do to improve Latency and Webpage Download times to catch up with the rest of the market.
TrueNet Webpage download times show Vodafone Cable as the quickest with Orcon (Fibre), and Snap (Fibre/VDSL) a close second and third in the new International comparison.
Best Speed consistency is with Snap(ADSL & VDSL), Orcon(ADSL), Slingshot(ADSL), Voyager(VDSL) and Telecom, all better than 95%. The best Fibre speed, Snap's 100Mb/s service, is just 93% of advertised speed.
The May TrueNet results show competition between ISP's to deliver the best broadband experience is intensifying.
Last month we were able to report fibre performance for Orcon, this month we have sufficient tests to report results for Snap. ISPs across all technologies are now reporting better than 90% peak to off-peak speed performance.
Slingshot had a major improvement with speed performance coming in 3rd this month after being last in April. Snap significantly improved Webpage performance with changes they made in early May.
Fibre performance from the UFB rollout is reported for the first time with TrueNet having a good sample of Orcon UFB connections.Overall Performance
UFB is an alternative to the standard ADSL service that all ISPs offer, and is best compared with Cable and VDSL services. Orcon's 100Mbps service is significantly better than either VDSL or Cable, while its 30Mbps service is a little better than both VDSL and Cable.Webpage Downloads
Only UFB Fibre provides a consistent technology for webpage downloads, with both Orcon's services achieving excellent results. VDSL performance is significantly better than ADSL with Snap and Voyager beating TrueNet targets, while only Snap achieves better than 95% in ADSL. Telecom's ADSL is very close, only dropping below the 95% after 3pm.Latency
Voyager is joined by Snap in achieving best National Latency figures in April. Large differences in International Latency between ISPs are significant in affecting the performance of voice and video services requiring always-on connections.
This monthTrueNet reports ISP performance across fixed line technologies using: Speed by Time of Day; time to download a Webpage; National, International, and regional Latency.
High Latency across an ISPs network can result in failure to download a webpage or delays in real-time traffic, but might not show up in TIme of Day and Webpage download results.
Thanks to funding from the Commerce Commission, TrueNet's monthly reports are more comprehensive than ever before. To enable a quick understanding of our research analysis we start with a summary of our results.
Of the six ISP products that achieved TrueNet’s speed performance target of 95% in January, only Orcon Capped sustained that performance to achieve the target in February.
Telecom speed performance fell for the first time, TrueNet understands that Telecom had a "network issue that has since been resolved".
Slingshot improved their unlimited plan performance to better that of many capped services, including their own capped service. "In February our Unlimited customers were the first segment of our customer base to be migrated to our new high capacity network core"
