Use special flag (HASH_FLAG_INITIALIZED) instead of (nTableMask == 0) to indicate that HashTable is allocated.
Make nTableMask to be 0 for packed arrays.
Remove checks fo HASH_FLAG_PACKED in zend_hash_find/zend_hash_del and family (string keys are resolved through uninitialized_bucket).
Change HashTable layout for better locality.

Drop duplicate arg from hash_get_current_key_ex

Small cleanups in hash implementation

* Drop unnecessary checks in non-inlined part of numeric key
detection
* Drop zend_hash_apply_deleter in favor of zend_hash_del_el.

cleanup

Simplify condition

first shot remove TSRMLS_* things

Improved zend_hash_clean() and added new optimized zend_symtable_clean()

Added new optimized zend_array_destroy() function

joined identical conditional blocks

basic clang compatibility on windows

Micro optimizations

fix datatype mismatch

move the more common case up

Optimized HashTable size calculation

eliminate one branch when computing the initial table size

micro optimized initial hash size calculation

most of the calls are with a size <= 8, so don't even bother any

Micro optimization for zend_hash_next_index_insert_new()

bring back all the TSRMLS_FETCH() stuff

for better comparability with the mainstream

cleanup TSRMLS_FETCH

Avoid double IS_INTERNED() check

Split big _zend_handle_numeric_str() into small always inlined function that makes initial check and regular big function

optimized colision list traverse

Remove HASH_NEXT_INSERT flag

We already pass ht->nNextFreeElement and the rest is handled by
ZEND_HASH_ADD.

Remove two more always-true conditions
