2 GB/s is pretty crappy, that’s about the burst speed of many nvme SSDs. Virtual disk should me more then 6 gb/s at least with ddr5.

- d3Xt3r 2y agoYes but bear in mind that those benchmarks were taken on an ancient system, with an ancient OS/kernel and FUSE: - OS: Ubuntu 14.04.01 LTS (64 bit) - CPU: Intel Core i5-2500K @ 4.0 Ghz - RAM: 8GB DDR3-1600 - GPU: AMD R9 290 4GB (Sapphire Tri-X) So that's an Gen 2 CPU, with DDR3 RAM and a PCIe 3.0 GPU. On a modern system, with a recent kernel+FUSE, I expect the results would be much better. But we also now have the phram kernel module, with which you can create a block device completely bypassing FUSE, so using phram should result in even greater performance than vramfs.

- vladvasiliu 2y ago> a PCIe 3.0 GPU Note that that CPU only has PCIe 2.0 according to Intel: https://www.intel.com/content/www/us/en/products/sku/52210/intel-core-i52500k-processor-6m-cache-up-to-3-70-ghz/specifications.html https://www.intel.com/content/www/us/en/products/sku/52210/i...
