Reviewers: Hannes Payer,
Description:
Remove high promotion mode
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 site that have
high
promotion rates.
Revert "Bring back high promotion mode to shrink young generation size when
scavenging latency is high."
This reverts commit 37be1d5e9e0a34abe6ba1612b9825e59f28a52d8.
Revert "GC. Delay/avoid entering high promotion mode"
This reverts commit a5221d0779d0839055c764b88f412a0793d959b3.
