Patch
Intel has released a patch to allow users to use a larger cache size, which leads to a reduced frequency of cache eviction and, thus, fewer transient snapshot generations. It is understandable that Intel adopts a strategy requiring minimal engineering effort.
Unfortunately, this approach is not ideal, as it only reduces the occurrence of transient snapshots without eliminating them entirely.
