[resolved] Questions about a good setup for W3 Total Cache on a VPS (7 posts)

    Hello,
    Our website started to get too big, so it's time to move to a VPS. The setup i have on my mind is Ubuntu 12.04 Server + Nginx + PHP-FPM + APC + Varnish... but my host said i would not need Varnish just yet, since we have around 10k daily visitors, and we would not see any performance gain. Is that right? I don't think so, but... they are the experts, not me.

    Also, i'm thinking about doing this:
    Page cache: disk (enhanced)
    Minify: APC
    DB cache: APC
    Object cache: APC

    I decided to do that way cause i saw Frederik saying here and there that disk (enhanced) is better for Page cache. Is that right? Should i use it for minify too or use APC for everything? Our server run SAS 15,000 RPM disks in RAID 10, with OnApp, would disk cache be fast enough?

    Thanks in advance :)

    apc for database cache
    disk enhanced for page cache
    disk for minify
    memcached for object cache

    those are ideal settings, if you're able to get memcached installed.

    Jonathan, can you explain why exacly i should choose Disk instead of APC for page cache? I mean, isn't memory > disk?

    Those are the settings that were recommended to me by the plugin author, so I felt like they were worth passing on.

    Cool, thanks a lot :)
    I'm just concerned about the disk cache... since i dunno if my disks are fast enough.

  6. The reason why disk enhanced is better for page caching with Nginx is because Nginx serves static files very fast without ever hitting PHP. When you use APC it's a PHP process which can be slower even though it's from memory.

    If your not convinced run tests on different settings to determine what works best for your setup.
