Just a thought, but can it be the reason with timing (e.g., rendezvous within (i)threads, hardware controlls without using hardware timer) problem? On FreeBSD, IIUC, multi processor (multi core) implementation assumes SMP (differs only clock speed) and end up with difference of performance at

This looks pretty weird to me, but I don't think it is specific to the FAT32. Just today I've first noticed that booting TrueNAS 12.0-U8 (http://download.freenas.org/12.0/STABLE/U8/x64/TrueNAS-12.0-U8.iso) (based on FreeBSD 12.2 with many backports) from NVMe SSD (I don't insist on NVMe so

Hi Guys, Any updates to support Intel P-core + E-core? I have filed a bug: PR 261169, but no updates. Does anybody know the progress? For Intel Adler Lake P core + E core processor (i7-12700T), copying files to FAT32 partition, the file
