Hi everyone,
I decided to try Pressflow out today. It seems to work pretty well when I when I replaced Drupal core with it but so far I haven't gotten Varnish to work with it. I did install Varnish but I've had some trouble with getting it to work on my server. Here are a few questions I'm hoping someone could help me with:
1). Does it make sense (or can you) run Varnish on a single server...that is...the same server that is serving up your webpage? I am confused about how I can have Apache listening on 8080 without seriously disrupting my sites. And I have multiple sites but I only want to run Varnish on one.
2). About 90% of my users are logged in members. Yes, I am running memcache with APC and I am also using block and views caching. Is there any advantage for me to use Pressflow if 90% of my users are logged in? I had heard that there might be some PHP 5 optimizations?
3). As my site gets bigger, might it make sense for me to have a master and slave database since my site is very read/write intensive? Lots of posting, updating statuses, and uploading pictures.
Thanks for your help!
