| |
This changes key characteristics (pages per-zspage and objects per-zspage) of a number of size classes which in results in different pool configuration. With zspage chain size of 8 we have more size clases clusters (123) and higher huge size class watermark (3632 bytes).
Please read zsmalloc documentation for more details.
