FILE_FLAG_NO_BUFFERING requires sector-aligned reads and writes. PrimoCache can't really force it because the program making the read is probably not accounting for that restriction.

If the dev has gone on a six-month vacation to Fiji and is currently laughing at our silly requests for an update, then perhaps I am upset. However, I am a lonnng -time professional developer myself. I know the idea above is very unlikely. I know that nothing ever goes according to plans or schedule...

I hate to necropost, but... windows software raid + windows default cache + primocache.... extremely overheading block size... additional firmware-raid running.... running games that read/write files potentially from archived-data-streams .... you really look into this crap of these noobs xD I'm act...

I'm pretty sure it's impossible to disable the Windows read cache. It's used for memory-mapped file I/O, which is a way of saying, "Make this RAM address range mirror what's in this part of the disk," kind of like a reversed virtual memory. Many programs use this, so you simply can't turn ...

I'm not FlyingCircus, but since I'm also seeing the problem, I'll also answer: Win7 Ultimate x64, 32GiB RAM, socket 2011 3770K CPU, with... Primo Cache 1 is on a Windows-software-striped 1024GB volume (game data, very fast): 12288MiB cache 16KiB blocks LFU-R R/W 10s deferred writeback Primo Cache 2 ...

Games may cache internally during a single run, in some cases, but if you exit the game and re-run, it's going to come from disk again (or cache). PrimoCache's own statistics say that game reads are, by and large, not coming from its cache at all in such cases. It would appear that only the .exe its...

... the table of "hot" data could be preserved, thus allowing the cache to be rebuilt much more quickly. As both a dev and a user, this makes the most sense to me. Save the previous state as a hint to rebuild the cache on next startup, but don't save the cache itself. Judging by the "...

Seeing the same thing with various different games. In a few cases, I see a hundred Kbytes or two getting read from cache, but mostly nothing. It claims it's got the full amount IN the cache, but doesn't report reading from it. Is this a side effect of game programmers using FILE_FLAG_UNBUFFERED mos...
