Northeast Consulting Resources Inc.: Internet Performance Slowing Down
A new study finds that despite overall improvements in performance, the
Internet may not be able to sustain performance-based applications in
the next century. The study was compiled using data from Keynote, an
Internet performance measurement company taken between October 1998 and
June 1999.
While the Internet has doubled it's delivery speed every 2 years, the
report opines that this is not sustainable due to overall increased in
delays on the Internet. According to Peter Sevcik a senior analyst on
the project, the Web will not be suitable for any serious
transactional business in the next century.
Roundtrip delays have grown from 240 milliseconds to 370 milliseconds
since 1995, largely as a result of the number of extra routers now
needed for information to reach it's destination.
The use of router hops, DNS look-ups, server re-direction, protocol
support, number and performance of advertising servers, complex screen
layouts, and content on additional server are slowing down the overall
performance of the Web by according to Sevcik. The topography and
overall infrastructure of the Internet needs to be redesigned or any
improvements already there will disappear.
Despite the forecast, overall performance has improved. The average Web
page, now 90,000 bytes up from 50,000 bytes in 1995 and 120 times more
complex since 1995, takes 6 seconds to download compared to 12 seconds
last year.
