Hello, fans. I’m running Plan 9(labs) on public QEMU/KVM service. My Plan 9 system has a slow read performance problem. I ran 'iostats md5sum /386/9pcf’, DMA is on, read result is 150KB/s. but write performance is fast.
My Plan 9 system has a 200GB HDD, formatted with fossil+venti. disk layout is: - 9fat 100MB - nvram 512B - fossil 31.82GB - arenas 159.11GB - isect 7.95GB - bloom 512MB - swap 512MB Also, I explained other installations. 1)200GB HDD with fossil only. 2)100GB HDD with fossil+venti. Read performance is fast (about 15MB/s) both installations. Could you tell me the reason?
