Re: [2021-01-30] PrimoCache 4.1.0 released!

You mean that we can see when it doesn't work without log ? Yes. For eg. if you set up 10GB L2 cache, and in the last normal Windows session, L2 has cached 4GB data and "Free L2" is 6GB. Now if you encounter an unexpected shutdown, before v4.1, L2 will be reset and after boot you will see...

Older versions (2.x if I recall correctly) gave the choice between LRU and LFU (Least Frequently Used) algorithms. It would be interesting to hear from support why LFU was removed, as th...

But theoretically, it will not be 100% but will increase and close to 100%. During the boot phase, some data has to be read from disks because at tha...

Re: L2 Striped Reading

As it is not increasing the latency until the L2 drive is maxed out, at which point it would be better to use the other drive. Software scheduling/processing also introduces additional latency. The implementation is not simple and ideal. Usually hardware solutions would be faster than software soul...
