heh. I tried to install clean debian 10,11 on the same box, with the same settings, and IOPS loss is just 10% instead of 90% in case of Centos. What does Centos hate on Proxmox and Dell h710 Perc? There is a maximum bandwidth of 40MBPs using Centos compared to Debian (400MBPs)... insane

Hi, i am testing above configuration with Proxmox 7 and Centos 8 as a VM. Setup: Raid level, virtual disk - 2x Kingston DC500M in RAID1 - Stripe 64kb - Write Back Proxmox 7 - using virtual drive from Dell/H710 as LVM storage Centos 8 : - VM in Proxmox 7 - drive sitting on that LVM...

Guys, I completely wiped that ZFS installation, installed it again on EXT4 - one SSD for a system, second one for VM.. Pretty oldschool one should say. The same VM with Centos 8, without ANY change inside the VM. Result? Load times from 20 seconds to 0.5 in admin area, bloody fast reading...

hello, dmesg or messages nothing special there root@dell:~# fio --ioengine=libaio --filename=/dev/sdc --direct=1 --sync=1 --rw=write --bs=4K --numjobs=1 --iodepth=1 --runtime=60 --time_based --name=fio fio: (g=0): rw=write, bs=(R) 4096B-4096B, (W) 4096B-4096B, (T) 4096B-4096B...

If you mean if I do know the difference between ondemand/static FPM settings etc, apache fine-tuning parameters, this is already done - apache and PHP are both sleeping and have sufficient resources. The same configuration on a different server respond very quicky, with 5x more websites...

Guys, there must be a real issue somewhere. I know 450 is a piece of sh... now, but listen: pveperf on (another boxes I have access to): GIGABYTE GP-ASACNE2100TTTDR card : 30.000 fsyncs Samsung SSD 860 - 20.000 My Kingstons - I am waiting almost 5 minutes and pveperf is unable to give me the...

Did you flash the SSDs firmware to the lastest version? +++++ yes Is your pool using the right ashift value? ++++ eeeh Is your volblocksize optimized? ++++ eeeh Did you optimize your php-fpm and mysql? ++++ yes, this is a level I understand pretty well Is your VM using virtio SCSI? ++++ yes...

Oh, i read it wrong. So you probably answered my question :( Thank you. So they are useless for that case..

yy i know this, the usecase for them is fine. The websites have no problem to restore backup from X hours back elsewhere in case of problem. The problem is just the speed here.

I know, but even 17000 IOPS should perform better. I do not talk about highend database systems, but if SSD of this kind load 10x slower than old Seagates, something is wrong (probably with the market)

Hello, I am long-term fan of Proxmox ecosystem, a lot of work has beed done to bring cloud to masses. As I typically search a lot before posting to forums, I am pretty out of mind now. A problem: 1) Latest Proxmox 6.3 installation on 2x Kingston DC450R rpool. 2) Dell server with 192G RAM, 24x...
