Millions of Americans wanting to enroll in Obamacare use the healthcare.gov official website. Just over one year ago, health care consumers were directed to log on to the healthcare.gov website starting on October 1, 2013. The healthcare.gov website experienced growing pains after its initial launch. Starting November 15, 2014 citizens were directed to the healthcare.gov website to enroll or reapply to avoid penalties for not having "minimum essential coverage." This article compares the website performance of healthcare.gov one year later. How does the popular site fare after one year of improvements?
The healthcare.gov website has evolved since the first time we reviewed the site. The site is more feature rich now and larger and more complex (see Figure 1).
The home page of healthcare.gov grew significantly in size and complexity over the past year. Page size grew by 85% from 677K to 1252K (see Figure 2) and total objects grew by 172% from 40 objects to 109 objects (see Figure 3).
With the larger page size and complexity, the page load times and "above the fold" times increased proportionally for healthcare.gov. The load time increased by 78.5% from 5.9 seconds in Oct. 2013 to 10.5 seconds in Nov. 2014 (see Figure 4).
The "above the fold" response metrics also grew by 62% to 67% from Oct. 2013 to Nov. 2014 (see Figure 5). The visually complete metric grew from 6.5 seconds in Oct. 2013 to 10.6 seconds in Nov. 2014. Google's speed index metric grew 67.6% from 4440 (4.4 seconds) to 7440 (7.4 seconds) over the same time period.
So the site is clearly larger and slower, but how consistent is the response time under load? The site takes advantage of Akamai and reportedly has more backend infrastructure. The site didn't have as many "waiting room" delays as before, but still spawned a few errors (see Figure 6).
One nice feature about the website is that you can create your health plan in stages, and come back later to finish (see Figure 7).
Unfortunately selecting a dental insurance plan spawned the following error repeatedly, despite numerous phone calls to the help line (see Figure 8).
This error code corresponds to a website issue. Users seeing this error are told to wait a while to see iand try again, or delete their 2015 plan and create a new one.
Let's take a look behind the screens to analyze why healthcare.gov is slower than before. The overall page results are shown in Figure 9.
The load time of the home page was 10.5 seconds (median run of 5 runs), with a TTFB of 0.85S and a start render of 2.71 seconds (which is actually faster than one year ago).
A waterfall (DSL) of the loading sequence reveals some issues (see Figure 10).
The home page has grown to 1.23MB requiring 113 requests. This is smaller than the average top 1000 page size (1807K) and about the same as the average number of objects (114, source httparchive.org). Here are the issues with the new healthcare.gov website (many of which are still there from one year ago):
While the healthcare.gov website has improved in availability and consistency, performance problems remain one year later. Healthcare.gov home page response times have slowed down by 62% to 78%, while page size and complexity have grown by 85% to 172% over the past year. We offer some triaged recommendations to improve the speed of healthcare.gov.
