Performance without cache
17 February 2011 at 3:11am Last edited: 17 February 2011 3:23am
Hi,
I have a problem. I've built a basic SilverStripe site that has very few visitors.
So when the visitor enters the site and the cache needs to be renewed it takes about 1min to load the page.Is there any fix for this? I've tried to find a fix for it but everything I find is "use the cache". Imo with or without cache 1min loading times are way to much.
Any help is appreciated! I really like developing with SilverStripe and would it suck to see it fall on the performance.
Ps. I use one.com to host the site.
This is my debug_profile=1 (which doesn't even show the true loading time):

the cache should only need to be recreated once - then it is reused over and over. AFAIK it's not going to be easy to speed up the re-create of the cache. Is something not triggering the re-create? have you created a 'silverstripe-cache' folder in your webroot?

I get the long loading time when no one have entered the site in a while (don't know how long).
The cache does work, I have the 'silverstripe-cache' folder and it gets filled with files.Can I some how set the cache life time to unlimited and that way only recreate the cache manually? Cause the sites content wont be updated that often.

If I were you I'd look into static publishing - skip the cache altogether...

If debug profile is reporting 473.5410 ms (100.00 %) OVERALL TIME and you think it's taking ~10 seconds then you may want to investigate other bottle necks as well. Possible things include connection to the server (loading javascript/ images and other front end files) or connecting to the database (esp if this is over a secure connection). If connecting to the database is super slow in your environment like swaiba said - try static publisher. Doesn't get much faster than serving html files.
