I saw it on a desktop, didn't think to see if it was ever used or not on motherboards for other types of machines, I just assumed that Z68 could be used on other places also. 2016-02-01 11:00 GMT+01:00 Tinker : > On 2016-02-01 16:33, Janne Johansson wrote: > >> 2016-01-31

Patrick, To sum up, neat to see that (from what we can see without having tested it,) there is (even inexpensive) hardware for this on the market, neat! My last question related to this would be, what if drives start breaking down (storage or CacheCade drives), would the OpenBSD system

This could be made in software with benefit, as a Softraid patch. So the frequently accessed stuff ends up cached on the SSD for faster read speed. ZFS on FreeBSD etc. does it in its "ARC"/"ARC2L" feature? There is some hardware solution, e.g. Intel made the

If there is nothing like this implemented in software in OpenBSD, * If someone implemented it, would there be interest to actually include the patch in OpenBSD? * Could a direct personal donation (separate from the normal donations to the OpenBSD project) to a developer be of use for

Ah, I now understand that this problem is mindbogglingly complex because of tons and tons of work needed to make it work, including the storage format on the SSD cache, and tools for "fsck":ing it etc etc. In a way that maybe answered my question, thanks! On 2016-01-31 19:00, Tinker wrote:

IMHO it's for misc. So, yes, feel free to donate to either OpenBSD foundation or directly to interested developer. I'm sure your donation will be appreciated. In your list you omitted two other options how to speed your hdd access: - buy more RAM and increase caching, on AMD64 it would probably
