it would not make a difference, notice how each of these scripts use script async="async"

 

thus you shop will load and these file will use asynchronous load, i.e. not block.

 

my two cents...happy day el

Very very marginally like el Patron said, but what it would do is break your site in older browsers, the shims are in there for a reason.

@dh42 @elpatron thanks to you PSPros. just came up as something to remove on GTMetrix. they took a large amount of the loading time. but if no difference or small difference then i will leave. i have read your replies on numerous topics has helped me. have a great day

[trevorgilligan]

also can i ask, my htaccess file is below. can i do anything to speed it up? im baseically looking for a generic htaccess file that will have as much as possible to speed up the website, such as this : mod expires headers, entity tags, cookie free domain, gzip, fewer http 

requests, CDN, leverage browsers caching, maxcdn and metacdn

 

also once i make changes in htaccess , do i regenerate in PS or do i need to do anythign else?

 

thank you again.
