Browser speed discrepancies September 22, 2011Posted by Duncan in PeopleTools.
Whilst troubleshooting the performance of an environment recently I used the PeopleSoft Ping utility. I’m aware that it isn’t a flawless measure, but for a quick and dirty check it’s a useful aid.
For those that don’t know, it gives a timing for each of the tiers in the Internet Architecture (Browser, Web, App and Database).
One thing that I noticed that I wasn’t expecting was the difference between browsers. If I ran a ping test to the same environment, at the same time, using different web browsers I’d get wildly different results.
As you would expect, the Database, App Server and Web server timings are broadly the same. The browser times are surprisingly different though. IE8 was consistently in the 0.33 – 0.35 range, whilst FireFox 6 was around 0.07. So IE takes approximately 5 times the time that FireFox does.
I repeated the test with different environments, and disabled anti-virus and all IE plugins but still the difference remained.
My curiosity was piqued so I repeated the test at home (against a different environment) still using FireFox 6, but this time IE9 and Google Chrome. Chrome was the fastest, closely followed by IE9 and FireFox trailing slightly (about double the time for Chrome).
This raises a question and suggests a number of findings:
Question 1) Why was my IE8 5x slower than FireFox, when all other parameters are the same?
Hypothesis 1) Internet Explorer 9 is significantly faster than Internet Explorer 8 for browsing PeopleSoft.
Hypothesis 2) Chrome is currently the fastest browser to use with the PIA.
I’d be interested to hear your results.
