[cisco-voip] callmanager 6 + opera = better gui performance

[Ronald Joseph]

i am new to the mailing list, so forgive me if this has been covered already. 

i installed cm 6.0 today for the first time, having only used 4.x before. i noticed the gui slowness seen by others. i use firefox 2 on linux. 

i initially thought it was platform-related (as others have), but dug a little deeper. i looked at the cm web code, and then compiled firefox for debugging. after a number of tests, it definitely appeared that the javascript engine (spidermonkey) was causing the slowness. spidermonkey has performed poorly for me in the past on other web applications i have tested.

so i looked for javascript engine performance optimizations, and came across this page:

	http://nontroppo.org/timer/kestrel_tests/

this page tested javascript engine implementations and found that opera 9.5 was the best by a large margin. so i installed opera 9.5 on my linux box and cm performance is MUCH snappier.

i hope this information is helpful. for firefox fans, i do not think javascript performance will get better until the tamarin engine goes into production next year. we'll have to wait and see.
