I am building full-ajax back-end, which consits of many quite big
partials. As the system grows up, performance is problem. After every
click, partial is refreshed, if needed. I am now at 0.5 sec / request. I
tried to simply disable ajax and the result was quite suprising: the
same page is rendered over 2x faster. I update 80% of page in case of
ajax. (Please dont tell: dont use ajax when updating 80% of page...
thats not the point.) So the ajax (page.replace :partial=>) is
significantly slower than non-ajax? Are there ways to improve
performance? I'am not very deep in rails, some suggestions?
