postgresql - Throttle Postgres I/O for debugging purposes -
in chromium devtools, can throttle network speed, useful debugging.
is there way throttle i/o speed of postgres server running locally?
there's no postgresql feature so. patch 1 in, though, adding small sleep in postgresql's buffer i/o routines.
instead, simulate slow i/o @ operating system level. particularly vm. or use nbd
(network block device) , rate-limiting tool trickle
.
or run else i/o heavy contend postgresql, , possibly ionice
postgresql.
