After trying every setting I am still asking the same question on a SG2100MAX 4GB ram 128GB disk and a NVMe 250 Optane m.2 drive over mpcie adapter. What is recommended disk cache ? Ufs aufs or diskd? What is the recommended memory cache? I currently have it set to ufs 16 level 1 folders For memory lru What should it be? Diskd? I have tried every setting from 256 level one folders to 32 to 16 every different type of memory catch types all the memory types schemes were using and I just can’t seem to find one that is performance wise the best so I thought After many years of trying that I should just email you guys .
