L1 to L2

Post by RobF99 »

I have an L1 cache that is read and write and I have L1toL2 checked. I copied around 80 Gb of data to a drive and about 60 Gb of that wrote to L1 and about about 20 to L2 because of the L1toL2 setting. But - At the bottom of the statistics, the Free cache (L2) number does not change at all.

This is a Vista 32 machine.

I would expect the Free L2 Cache to go down in value but it does not. Can you explain what is going on there?

We have tested it according to your response, but we did not find the same problem as yours.
Could you open your PrimoCache, choose/highlight the target volume item in the main dialog, and then make a screenshot of the PrimoCache main dialog and sent it to us? We'd like to see how the cache is configured and used.
Besides, please look at the changes to the Total Write(L1/L2) and Free Cache(L2) as you copy the data.

This is strange but I cannot reproduce the problem today. I definitely saw it happening the other day when I was copying the 80 Gb of files, but now it is working normally. I apologize if I gave you a red herring to chase.

I was able to reproduce it again, but this scenario is different to the last. The last scenario I was copying 80 Gb files. This time I was operating a program that did quite a bit of constant reading and writing so most data would have already been in L1. Notice here that is says that 621.47 went to L2. But at the bottom Free L2 - this remained at 47.54 Gb always and did not change. I see that only 60% made it to the disk but if some went to L2 it should have changed the Free L2 cache. Yes?

Further - I then copied 8.8 Gb and it seems that the numbers updated correctly. Maybe the instance above with the screenshot and 1.15 Gb, it might just be semantics of the output of what is going to L1 and/or L2.

We don't find any problems in this screenshot. 1.15GB is the data to be written (requested by Windows or other applications). If L1 writes to L2, Total Write(L2) will increase and Free Cache(L2) will also change.
