sourceware is being very slow at present, with dmesg showing RAID errors
on sdi that may well be responsible, e.g.:

Thanks, I am engaging on-site sysadmins to swap that disk.

In case you didn't already notice it, there's a message shown by dmesg:
[86524.889900] megaraid_sas 0000:15:00.0: 95 (569544782s/0x0008/FATAL) - Battery has failed and cannot support data retention. Please replace the battery
(I don't know if that would affect performance at all, if e.g. it means
any hardware write caching is disabled.)

Yup, aware of it; nope, shouldn't really affect anything.
The NVMe SSD is the primary/gating target for I/O traffic.
