I'm working with Plone 4.0 on Ubuntu. (I know I should upgrade, but I'm working towards that...)
So I have a plone site that I have put onto a development server. I haven't set up reverse proxy with nginx yet. I am just using it as a test for now, so I don't need to do that yet. I start the server, pretty much like it is described in here https://docs.plone.org/4/en/manage/deploying/production/ubuntu_production.html
Now it works fine, so I stop the server and put in my own blobstorage and Data.fs files. This is a site that's been running on a different server under the same version of Plone. I start up the server and it works great.
However, when it first starts up, and I go to it in my browser, it takes maybe 2-3 minutes before responding.. I figured that's just the server starting up. Then I navigate around the site and it's fine, it's fast as any other site.
But if I go away for 5 minutes and come back to it and click another link, again it takes 2-3 minutes of spinning before responding with the page. If I click again on another page, then it is back to normal response times again.
It's like it went to sleep or something when I went away and had to wake up or something. (that's just the feeling I get). I tried it with the default install (blank new Plone site) and it was fine, it did not have this delay problem.
Any ideas what's going on here? Thanks,
