[Opensim-dev] HUGE ASSET CACHE

[Frisby, Adam]

It will do that for you, to a degree.

Remember that File.Close is synchronous; not Async. It will wait for flush before returning. Ergo, we need to do a little bit of additional caching I think.

shouldn't the OS do that for you? or are you syncing the disk on writes?

if the disk is thrashing, something else may be wrong

I think the ideal disk cache needs to do things Async with a small memory cache.

Probably a 5 minute mem cache with a long-term store on disk. All disk operations need to be done ideally async for storage. (obviously retrieval is another matter entirely).
