All vehicles passing through Skyway, SLEX, NAIAX, STAR tollway, and TPLEX will have to be installed with a radio frequency identification (RFID) sticker in order to be allowed entry starting November 30. Motorists need their vehicles fitted with Easytrip RFID stickers in order to use NLEX, SCTEX, Cavitex, CALAX and C5 South link by December 1.
While the Department of Transportation moved the deadline for cashless payment on toll roads, the queue along toll gates that allow installation of RFID stickers has reached an insane level where some motorists complained to have waited as much as five hours to get their stickers. This prompted toll operators to require motorists to get an online appointment first before going to installation sites.
The problem is, as of this posting, both the RFID registrations sites of toll operators could not be accessed by motorists who wish to get an appointment.
Looks like the registration websites have crashed due to the deluge of users that overwhelmed the system. Motorists came in droves to register online as walk-in applicants for the RFID sticker will no longer be entertained in installation sites. This is the same thing that happened to Davao City’s DQR system last week where thousands of users flooded the system by accessing it at the same time.
The major cause of traffic-related website crashes is a mismatch between the number of users coming to a website and the capacity of the site’s infrastructure to support this volume of visitors coming in simultaneously.
In an interview with BNSHosting founder Wilson Chua, he said that in order to make the website functional despite of the number of people accessing it, two things should be considered. First, the need to increase the web server resources, and second, the need to optimize the code. He further explained that people manning the system need to monitor the resources like memory, CPU utilization, bandwidth, and disk usage then figure out which of these resources is causing the bottleneck. Upon knowing which, it is then a must to apply more resources and re-examine the code to reduce the demand on that offending resource. This is Mr. Chua’s suggestion to the city government of Davao which I believe is also applicable to the problem both the tollway operators are facing right now.
