Jacek Sieka f3a56002ca Turn payload into value type (#2483) ... The Vertex type unifies branches, extensions and leaves into a single memory area where the larges member is the branch (128 bytes + overhead) - the payloads we have are all smaller than 128 thus wrapping them in an extra layer of `ref` is wasteful from a memory usage perspective. Further, the ref:s must be visited during the M&S phase of garbage collection - since we keep millions of these, many of them short-lived, this takes up significant CPU time. ``` Function CPU Time: Total CPU Time: Self Module Function (Full) Source File Start Address system::markStackAndRegisters 10.0% 4.922s nimbus system::markStackAndRegisters(var<system::GcHeap>).constprop.0 gc.nim 0x701230` ```		2024-07-14 12:02:05 +02:00
