12. Toad Notes Go language--garbage collection
Garbage collection involves: threshold triggering, parallel tagging, and concurrent cleanup.
Or: Periodically forcibly reclaimed, freeing up physical memory.
Garbage collection efficiency is always at the heart of the Go version upgrade.
Threshold or Forced collection
Serial or concurrent execution with user logic
If the threshold is too large, a garbage collection may not be triggered for a long time. Therefore, it is mandatory to check for recycling every 2 minutes
is very necessary. Every 5 minutes, the physical memory of the heap is freed for a long period of idle blocks.
In addition, in UNIX-like systems, physical memory is freed by recommending that the operating system kernel de-memory maps, but not the virtual memory. When used again, the kernel is re-provisioned with physical memory due to a fault of the pages.
