This snippet sets the Streaming GC system to sparse mode. In this mode only the preallocated amount of Streaming GC nodes is allowed. Keeping a low amount of Streaming nodes is interesting for performance optimizations.

engineStreamingSetProperty( "gcOnDemand", true );
engineStreamingSetProperty( "infiniteStreaming", false );
engineStreamingSetProperty( "strictNodeDistrib", true );

This snippet turns on fibered loading when the Streaming system is busy and leaves it that way for five seconds.

engineStreamingSetProperty( "isFibered", false );

local lastBusyTime = false;
local fiberedDuration = 5000;

addEventHandler( "onClientRender", root,
    function()
        local isBusy = engineGetStreamingInfo().isBusy;

        if ( isBusy ) then
            local now = getTickCount();

            if not ( lastBusyTime ) then
                lastBusyTime = now;

                engineStreamingSetProperty( "isFibered", true );
            end
        elseif ( lastBusyTime ) then
            if ( now - lastBusyTime > fiberedDuration ) then
                engineStreamingSetProperty( "isFibered", false );
            end
        end
    end
