    Remove high promotion mode · 40bb3a58
    mlippautz authored
    High promotion mode limits new space size in the case where many objects (high
    rate) are promoted.  The result is frequent scavenger runs with low pause times. The
    approach conflicts with pretenuring which requires a larger new space size to
    collect enough feedback to be usable.
    
    Ultimately the goal is to have pretenuring catch allocation sites that have high
    promotion rates.
    
    Revert "Bring back high promotion mode to shrink young generation size when scavenging latency is high."
    
    This reverts commit 37be1d5e.
    
    Revert "GC. Delay/avoid entering high promotion mode"
    
    This reverts commit a5221d07.
