MIUI 12.5&13 修改 ZRAM 大小

配置文件在/system/etc/perfinit.conf

老机型可以尝试修改下/system/etc/mcd_default.conf的文件。

物理内存（8G）：对应的zram 大小（6G）

以/system/etc/perfinit.conf为例

"zram_size": {
     "def": "512",
     "2": 1024,
     "3": 1536,
     "4": 2252,
     "6": 4096,
-    "8": 6144,
+    "8": 5120,
     "10": 6144,
     "12": 6144
  }

下面是修改好的数据，8G 物理内存开 5G Zram
