Hi,

I set a cache with defer-write(60sec) and L2cache(SD card 2G).
When I listen the mp3 music, it will skip and repeat sometimes.
It seem that the music player will read/write some data for buffering the music file.
And defer-write with L2cache may effect the speed to get the buffer info for the music player.
IF I re-cache the content of the cache or stop the PrimoCache, then the problem will be solved.

So, can I set some exclude folders for PrimoCache?
Or is it possible in the future version?

Thanks in advance,
Zhxiang

Sorry, currently PrimoCache cannot do that. It is a block-level caching program and it's kind of difficult to support such feature.

I am not sure a SD card is the best choice for L2 cache. Many have slow/variable write speeds and often don't do well with simultaneous requests. The card reader itself and how it interfaces with the computer (IO bus) can also impact overall performance. If available, you may want to run a quick test with an external SSD (or even a HDD) to see if the SD card itself is the culprit.

I realize your question was about excluding certain files/folders from caching but that really runs contrary to the architecture of PrimoCache as I understand it.

It seems that the same request in different posts can get different answers...

For the guy who bought a license, support will think about it, but here, the answer is just: impossible.

Wow - the conflicting posts from 'support' came just 2 min apart!! Who knows if it was the same person. I definitely like the other response better as tuning the cache would certainly be a primo feature. Bad pun aside, I have used this capability on eBoostr (my preferred read-only caching solution prior to PrimoCache) to good effect. Higher end/enterprise caching solutions almost always include some tuning ability although I would think this might add significant complexity to a block level architecture, especially if files are relocated on the storage medium with any frequency.

Yes, even for a block level caching architecture, it is still possible to exclude some files. However, as you may already know, the method to implement such feature is quite complicated and difficult. And the method is not perfect, especially if files are relocated.

We do understand the user request for such feature. We are also thinking other methods. And we may support it in future versions, but currently PrimoCache cannot do it.
Thanks.

I understand now.
