[OpenLayers-Users] Re: Updating Data: Comet, Push, or What?

[Arnie Shore]

Have you done any measurements that tell you where the server-side time 
is going?

If it's database access - and you're satisfied that your schema design 
is optimal - then solutions to that problem include some variations on 
the following.

a.  A caching mechanism that would update the cache at a rate you 
select, rather than at the rate of visits.

b.  Create a static page that often, and respond to users with that 
static page.

Client-side, if memory is being consumed and not returned, then forcing 
a page reload can clear that issue.
