Optimizations:
- ringbuffer: optimize Len(), IsEmpty(), Discard(), Clear() methods with
branchless arithmetic and simplified logic
- fec: fix memory leak in shardHeap.Pop() by setting element to nil before
truncating slice, preventing GC from holding stale references
- timedsched: fix memory leak in timedFuncHeap.Pop() with same nil-before-truncate
pattern; optimize prepend() using slice swap instead of append
- autotune: add sortCache field to Autotuner to reuse slice allocation in
FindPeriod(), avoiding repeated allocations during period detection
- snmp: replace fmt.Sprint with strconv.FormatUint for better performance
in Copy() and Reset() methods
- entropy: remove defer overhead in rngAES.Read() and rngChacha8.Read()
hot paths for reduced function call cost
- bufferpool: pre-allocate ErrBufferPoolSizeExceeded error; reset slice
length on Put() to allow proper reuse
- sess: remove defer overhead in 6 setter methods (SetWriteDelay,
SetWindowSize, SetStreamMode, SetACKNoDelay, SetDUP, SetNoDelay)
These changes reduce memory allocations, fix potential memory leaks in
heap-based data structures, and eliminate defer overhead in frequently
called methods.
