October 24, 20241 yr 6.12.13 Been running Unraid for close to a year, have never really been happy with the performance having to really watch scheduling of events even though the CPU utilization never went above 35% at the worst of times. And typically well below 5% Have a Dell R730 server with 28 cores (56T), 12 disk array with 2 parity drives. All HDD Currently only have one cache SSD drive. Crucial/Micron Client CT2000BX500SSD1 Had 2 originally but that was even slower. Well I recently upgraded my Internet to 1G both ways fiber and that has brought my server to its knees. Install Glances and Netdata after seeing others using the apps to troubleshoot. Netdata flagged this for me. After this happens everything go south very quickly. Installed DiskSpeed and ran that. After continuing it gets stuck at. Are there any known issues with the hardware, drives I am running? The SMART reports are happy and clean. Thanks much. Edited October 24, 20241 yr by 8kMarina

The one that is being added to from the Internet? If so Yes. Well I have the RAID controller setup as just normal in the controller BIOS. Can't remember the terms. Actually I can not move it right now, as the physical server is unavailable to me. BUT, I can at a later date I believe by moving it to the back of the machine. I believe these slots are more for boot up but may work. So you saying this drive has not be optimized "TRIM" since I started my server? Any way to manual trigger a TRIM?

Still TRIM issues? Yet, doing more research this controller DOES support TRIM, or is it a Unraid limitation? Just a shame the performance is so poor. Edited October 25, 20241 yr by 8kMarina

AFAIK only LSI HBAs in IT mode support TRIM, and even those have some limitations: https://www.broadcom.com/support/knowledgebase/1211161496937/trim-and-sgunmap-support-for-lsi-hbas-and-raid-controllers
October 25, 20241 yr Author Well that is the wrong controller. These systems have a H730 or H730P (The P is just larger I believe) https://i.dell.com/sites/doccontent/shared-content/data-sheets/en/Documents/Dell-Poweredge-RAID-Controller-H730.pdf See Key RAID and data protection features The HBA is what I enabled on the controler.
