Keep format clusters and Primocache L1 block size at 4k for maximum IOPS performance. Deferred writes (with a UPS on the machine) can still help, though it's less of a concern with a NVME. I usually recommend no less than a 10% RAM-to-Data sizing, so if you have 100GB of data to cache on your NVME,...

Well, given the fact that some SATAIII SSD (good controllers + fast MLC/TLC NAND) are faster than NVME M.2 (bad controller + weak, slow TLC NAND) when it comes to high load, you should look at benchmarks that hammer SSD with lots of work, like encryption (encryption is showing real-world NAND perfo...

I have tested primocache extensively with samsung nvme drives and optane 900p. Primocache further increases low queue depth transfer speeds to 600-700Mb/s (from optane's 200-300 Mb/s) but the real-world performance does not increase (at least with my workloads). the issue seems to be with a) window...

RAM performance is much better than a SSD. When using ram caching, 1) For reading, when data is hit in cache, of course the access speed will be faster than SSDs. However, usually the amount of installed ram is much smaller than a nowadays SSD. So you cannot assure 100% hit rate. Besides, ram is vo...

Hi So could PrimoCache with alot of ram actually enhance nvme performance in theory? I am particularly interested in random low queue reading for nvme, as typically nvme never hits ever past 82mb/s with that, while intels xpoint optane claim to fame is that low queue performance with q1t1 being arou...
