Hi all,
On large capacity volumes (>9Gb and above) what sort of throughput
performance hit should we expect for minimum free space threshold less
than 10%. According to the man page [tunefs(8)]: "this value can be set
to zero, however up to a factor of three in throughput will be lost over
the performance obtained at a 10% threshold.
Do I really need to reserve 10% on a 23Gb disk? This results in
reducing the capacity by 2.3Gb! Or perhaps I should reserve a certain
amount? Say,
reserve 0.4Gb (or 10%) on a 4Gb disk capacity
reserve 0.4Gb (or 2%) on a 23Gb disk capacity
Any comments would be appreciated and summarised.
Regards,
Rich
