GWT RIA performance in IE8 -


we've got application on gwt 2.5.0 + gxt 3.0.4 1 main page, containing big table (like excel) , couple of heavy popups (implemented using gxt windows). works reasonably @ chrome, ff, , ie9 incredibly slow in ie8.

memory consumption on opening main page , heavy popup follows: ff ~250mb ie9 ~230 mb ie8 ~600-700 mb (!!) don't think it's memory leak, because memory stayed stable , didn't increase overnight.

compiler settings 'use closure compiler + max optimization'.

i'm @ loss start, , how fix problem. 1 idea rendering fast in ie9 not in ie8 because of gpu acceleration, doesn't explain amount of memory needed ie8. why ie9 okay, not ie8 ?

we're profiling our application dynatrace, doesn't memory usage. ideas appreciated, thank !

css - Text drops down with smaller window -

i've adapted css use in website , can't quite figure out why 1 aspect of page acting way acting. basically, when shrink window below size horizontally, of text "drops down". becomes issue if user viewing website through ipad vertical orientation. can view issue here . i'm hoping make if window gets smaller, placement of text remains intact. the problem area not have enough space put both side navigation , content on 1 line. make automatically adjust page's width when exceeds decrements of width. this code example, , highly unlikely work. if see css more clearly, provide exact code. @media , (max-width:960px) { /* assuming #wrapper 960px across */ #content {width:560px;} /* opposed 720px */ } edit the content drops down @ 980px, have shrink width after there. @media , (max-width:980px) { #container {width:520px;} }
