I just know that IE is a pain to deal with. I assumed that IE9 would be better at doing certain things and be more standard it is way to render web pages. I learned from that mistake.
We have an application that can list all items tracked in a table. The convenience is for users to quickly do global searches or to import this data in excel to do the manipulation they need.
When the table reached 1500 elements I received emails asking me what I changed to make it so slow in IE.
After some testing I realized that IE was rendering that web page in “quirks mode” which is not very efficient with large table.
After looking for a few minutes on Google I found an MSDN article talking about adding this header to tell IE to use the latest rendering engine for this page:
It is now applied across the site and IE9 performs fine but IE8 still shows some signs of slowness. Maybe more a computer issue that an IE issue but I can’t verify.
During my search on this IE issue I certainly came across a fair amount of displeased programmer with how IE does things (even in newer version) and I can see why. Hopefully I won’t be bitten too often.
