[wsrp-wsia] [change request #249] Class name length impact on performance

This came from an internal review by our "performance
police":

Document: Spec 0.92 

Section: 10.5 CSS Style defintions

shorter class names

Reasoning: 

Please strongly consider using *much* shorter names for these CSS elements.
 We already have network latency/transmission issues due to the size
of our existing CSS files because they cannot utilize browser compression.

 

Long names in the CSS definitions lead to large CSS
files and noticably slower download times.  Additionally the "source"
HTML pages that refer to the CSS's will be noticably larger as a result
of these long names.

To give a concrete example, consider a centralized
Portal server configuration, ie HQ/MOC, with a remote client in Singapore,
operating over a fairly standard 200ms latency network.  Transmitting
a 10k CSS file will cause ~6 round trips due to network startup costs.

 

Overall loss due to network Round trips = 220 * 6
or ~1.3s
