Write-through (WT) introduces a significant amount of network traffic leading to an average 73% slowdown vs. ROBUST.
MC_DISABLE only operates a quarter of the cache capacity at low-voltage leading to an average 12% slowdown. While MC_WB slows down performance by 16% on average due to the extra writeback traffic,
the other two mechanisms improve performance by 3.5% (MC_SWP) and 2.6% (MC_DUP). Compared to MC_DISABLE, MC_SWP improves performance by 17% while MC_DUP improves performance by 16%, on average.
