Expanding on the downstream summary: maxValidateMBPerSec only affects validate cmds running with [background:true} specified. maxValidateMBPerSec defaults to 0, which is interpreted as off and no throttling will occur. Each validate cmd will obey maxValidateMBPerSec separately. They do not share throttling. So, if maxValidateMBPerSec is set to 5, three concurrently running validate w/ {background:true} cmds will throttle at 15 MB per sec, each staying below 5 MB for itself. maxValidateMBPerSec is a startup and runtime server parameter. Already running validate cmds will pick up on a change to maxValidateMBPerSec and act accordingly – so if a background validate cmd is causing too much performance degradation, the user can set maxValidateMBPerSec such that validation uses less resources. maxValidateMBPerSec will have no affect on validate cmds where {background:true} is not specified. |
