Any chance of including Memcached support in next XFS release ?
Or can this be done by custom mods ?

Admin ? or anyone from staff can comment on this ?
This will help with main server loads, as lot of I/O will be reduced. |

for database
so we can cache (ram) and would never hit database (disk) unless needed |

Memcached is RAM-only cache, so on reboot you will loose all your memcache data. This is strongly limit us since almost all info is importnat for us.
XFS almost don't have STATIC pages like Blog posts or single pages.
We can't cache Upload / Download / My Account / My Files pages since info could be updating there each second.
I'd like to cache something but really can't think the best way to do this. |

Ram-cache is for read & not writes; it does write to disk at on inserts.
Facebook has 200TB of memcache servers ! , they are used for a reason; disk isnt as fast as it should be. |
