The mempool.space site is powered by FreeBSD with ZFS root and ARC cache for maximum performance. Linux probably works fine too, but why settle?
### Filesystem
For maximum performance, I use 2x 1TB NVMe SSDs in a RAID 0 using ZFS with lots of RAM for the ARC L2 cache.
```
# zpool list -v nvmraid
NAME SIZE ALLOC FREE CKPOINT EXPANDSZ FRAG CAP DEDUP HEALTH ALTROOT
nvmraid 1.81T 1.04T 787G - - 0% 57% 1.00x ONLINE -
nvd0 928G 535G 393G - - 0% 57%
nvd1 928G 534G 394G - - 0% 57%
```
For maximum flexibility of configuration, I configure the partitions separately for each data folder:
