Anyone running ZRAM on Proxmox 8 hypervisor on a modern Mini PC with 96 GB RAM?
Given an AMD or Intel Mini PC with Crucial 96 GB DDR 5 Laptop Memory kit, i am wondering what would would be the sweet spot of ZRAM Swap amount and which compression option to use lzo, lzo-rle, lz4, lz4hc, or zstd.
- Running without ZRAM baseline
- What is the most amount of ZRAM swap we can add to a 96 GB DDR 5 mini pc with decent performance?
- What is the most amount of ZRAM swap we can add to a 96 GB DDR 5 mini pc with a stable system benchmark
Found some old online articles that claim a ZRAM swap of up to 8 GB can actually improve performance with the claim that the processor can decompress and compress the memory in real time. @wendell mentions this in a few YouTube Videos, but not entirely sure how to do a benchmark for this.
@wendell had a great youtube on the Bee-Link GTR7 Pro ( The GTR 7 is Amazing! But mine brokeā¦) 11 months ago. I purchased one and upgraded to the 96 GB RAM crucial kit and also added 2 2TB 990 Samsung SSDs. I had a few bugs that were ultimately fixed in BIOS updates, in Proxmox 8.1 and also adding /etc/modprobe.d/zfs.conf. So now the system is very stable and performs well. Running Alpine Linux VMās with docker that are all relatively lightweight on memory pressure. This system replaced and outperforms a Z440 HP Workstation with a Xeon 2690 CPU and Samsung 970 Pro NVME drives. This HP Workstation has 128 GB ECC DDR4 memory.
Be very cool if the GTR7 Pro could have a 32 GB ZRAM swap and see if it compares to a Xeon 2600 v4 generation server with 128 GB DDR4 memory.
