Right configuration

  • Hi,

    I am using AWS (setup through Bitmani) – macro instance (VPS – 1GB RAM).

    I enabled Disk cache for Database and Object cache. After that my CPU spiked from 10-20% to 100% for 20mins and then it was consistently using 50-70%. Now my CPU credit balance is completely exhausted :(.

    I Googled for optimal usage guidelines but haven’t found something good.

    Considering all modules can be installed in my instance, what is the optimal setting for following features?

    1) Page Cache module
    2) Database Cache module
    3) Object Cache module
    4) Minify module

    Which one should I use- Disk or APC or eAccelerator etc something else for above options? Because of wrong settings my server was screwed and I had a huge downtime ??

  • Don’t run object cache through disk thats not good. The same goes for database caching on complicated websites you could generate 12k + inodes and this will cause cpu spikes.

    Run them through APC/MemCache or use a redis cache.

    Thanks @destac. I updated the settings of Object and Database to APC.

    What shall be the cache method for Minify and Page Cache in EC2 macro instance? Shall I make everything APC?
