Don't forget that as of MT 7.5 patch 4 there is a option to pre-load the cache with everything when MT starts. Using this with persistent cache and the new sync cache features and this should be a very powerful combination. I do have some questions as to how this works with how MT caches based on a user's groups. Maybe it just caches everything?
My only concern is pre-loading everything on a 32-bit process may eat up a lot of resources. When we tried it we started getting heap errors after a while. However this MT server is not too terribly happy in general anyways and we still run out of memory with pre-load off. It will be great when the day of 64-bit MT arrives :) Jason On Thu, Apr 15, 2010 at 3:55 PM, cpgold <[email protected]> wrote: > ** > You are right, no way that the midTier stores prefetch items on the client > computer. > Unless you acknowledged security bypass for your browser > Prefetch runs as an assumed user login.
