Page does not get loaded

First thing to check is whether the issue is the calendar. Try adding a block with a Calendar ID of "usa__en@holiday.calendar.google.com" and see if that is slow to load as well.

Try enabling "debug" mode under the admin page and let me know what that produces. There will be a lot of text all over the page, but some of it should be helpful.

Are there any errors listed under "Recent Log Entries" in the admin panel?

If it's appropriate, what is the calendar ID you are trying to display?

You could also try disabling cache by leaving the cache line blank. That's unlikely to make it load faster, but you never know.

Give those suggestions a try and let me know how it goes.

I found a potential bug that was setting the cache time to 0 in all cases. This could make for a slow page, but not more than a 5-10 second load time in my testing.

I checked the changes into CVS, it should be included in the nightly build tonight, or if you want it sooner, grab version 1.6 of gcal_events.module and test it out.

I also cleaned up the debug_mode output and added some timing tests in there so you can see how long it takes to initialize the XML parser.

What versions do you have for simplepie.inc, gcal_event.module, and php? As a comparison, I'm running simplepie version 1.1.1, gcal_events.module version 1.7 and php version 5.2.6

Your diagnosis sounds reasonable - if it gets up and past feed-init() but can't seem to run get_items() or even get_item_quantity(), that is most likely a simplepie problem. You can try erasing the cache and forcing it to re-download, perhaps? Or delete the cache directory and disable the cache entirely?

Also, if you have more than one block enabled, try reducing it down to just one block and set that block to be the holiday calendar.

In the gcal_events_contents() function, you can return text at any point and have it display in the block. That might help in your debugging. Right before it calls feed_item_quantity() for example, you could have it return and display the amount of time it took to get to that point (a call to microtime(true) and subtract $start_time). SimplePie may have some status checking functions available that are worth looking at. I'm not positive on that, though. If you comment out the feed functions or return from the function early, the debug messages should show up.

Somethng else you might try: replace the call to $feed->get_items() with $feed->get_items(0,5). That should only get the first 5 items and should (hypothetically) take much less time to complete. Then again, the test holiday feed doesn't have very many items in it at all, so the entire thing should only take a few seconds anyway.

Sorry I'm not more helpful, I can't reproduce the error or even imagine what it could be. Keep posting your progress, though, or let me know if there's any other information that might help.

Thanks for investingating this. I'm at a loss to explain it as well.

Something else worth trying: Modify the module code so that it can be run from a commandline. Just have it hard-code the calendar ID and spit the results out to the screen. If that works fine, see if it still works when called from the webserver (but not with drupal). Perhaps there is some kind of conflict with another drupal module?

I just installed the acquia_marina theme to see if I could reproduce it. Calendar seems to work fine with the default settings for that theme. I tried to change some settings, but none of them seemed to have much of an effect, the calendar just displays fine in all cases.

Too old to be useful...
