Embedding subset font,small size but computer lags

hi,

embedded some characters using embed tag in flash CS3(font.swf) .
2 separate swf(a.swf,b.swf) loads the font.swf on runtime.
these 2 swf are being called from a container(parent) swf.
it looks find locally and not time consuming to load.
but when i view it from a server, computer lags after a while…
(all file sizes are relatively small.around 160kb)

what needs to be done in order to prevent computer from lagging?
is it better to load font.swf not in separate swf but directly in container(parent).swf?
:frowning:

thanks
