h:selectOneMenu performance - any suggestions?

[damianharvey]

I've got a drop down with a list of all Countries (246). This is taking too long to render on my page (roughly 4 seconds).

I've tried 4 different options:
1. Using s:selectItems and s:convertEntity
2. Using f:selectItems populated at login (session scoped)
3. Using a static list of f:selectItem(s) with primitive values that I ui:include
4. Using plain HTML

1, 2 & 3 all take about 4 seconds to render. HTML takes about 1 second. So this isn't a Seam problem - it's a JSF rendering issue.

I've tried using s:cache but I can't get it to work with drop-downs (can you even do this?). It works fine with text.

Can anyone suggest a way to speed up selectOneMenu?

Thanks,

Damian.

s:cache is really useful for output only components.

Have you tried http://jira.jboss.com/jira/browse/JBSEAM-2185 - I will get this into Seam as soon as we start work on 2.0.1

But I can see that it would be useful to be able to cache the created dropdown list (in it's generated form). Create a JIRA issue, I'll see what I can do.
