    Yes, Supercache should work fine with that combination as it doesn’t interfere with hyperdb.

    thanks @donncha i’m almost ready to try it out …. on w3 total cache i was using opcode caching apc for database …on your plugin you don’t deal with caching any database stuff yes? does that mean i should use memcache plugin with wp super cache and hyperdb?

    thanks so much for the amazing plugin i just used your cdn feature for the first time (used your caching long time now) and cdn is beautiful working with multiple cnames etc

    Yeah, use the memcached plugin or db cache reloaded too but supercache only caches the page output, not anything in the db.

    thanks i’ve never set up master slave mysql databases before so this is a huge help to me and hopefully others …. i’m a little confused as to what memcached does …it seems like it also caches pages like yours does but stores them in memory instead of disk…. is that right? or is memcache plugin configured just for mysql database caching? (another thing i’m confused about mysql has caching of its own so do i need to even look for database caching plugins for wordpress)

    i have not looked at db cache reloaded but if that will help speep up queries in the master and slave for LOGGED IN users then that’s what i need to do

    my configuration right now is

    1 web server running all php, apache, wordpress …and using its mysql server …then another server which is a bare bones mysql only server that is the slave …. i am running wordpress, buddypress, wp-super cache (page caching and cdn) …. hyperdb for load balancing …..now the piece i seem to be missing is database caching which i’m thinking the memcached plugin OR db cache reloaded iw what i need…. if you were me what would you use?

    thanks!

    PS i just went to the db cache reloaded plugin and lots of people saying its broken for 3.1 http://wordpress.org/support/topic/plugin-db-cache-reloaded-plugin-broken-with-wp-31?replies=32

    @donncha …. does memcache plugin for wordpress speed up queries for logged in users? i’m thinking your plugin takes care of non logged in users with static html pages …. Ryan borens memcached plugin ..how does that work with wp super cache?

    The memcached plugin caches the output from queries, rather like mysql caches them but at a higher level. It’s worth using. That’s completely different to Supercache which caches the whole page, higher level again!

    thanks so much for the reply … i tried the memcached plugin and it worked for awhile then the site stopped working and started downloading any requested php file instead of executing them…. when i deleted the object-cache.php file my site came back …. i looked at the error logs and i actually opened one of the php files and saw it was inserting a php error before the doctype declaration: is this because of memcached do you think ? i have been scared to use again as i don’t know what caused this and never have seen anything like it …. any ideas would be great i know its not directly related to your plugin but i’m sure others will be wanting to use andy’s memcached plugin with yours. … now i’m thinking about trying the plugin for apc object cache nervous again but maybe worth a try … i was getting great performance from apc using w3 total cache but can’t use that because of hyperdb incompatibility

    Look at the error message, it’s something about timezones. I don’t recognise the error but you might be able to fix it by setting your timezone in the WP settings page.

    I am facing a issue with W3TC and HyperDB. Is there any way to make it work for database cache?

    Please help. Thanks
