Since 2009, Nokogiri has configured libxml2 to use ruby_xmalloc et al for memory management. This has provided benefits for memory management, but comes with a performance penalty.
Users can now opt into using system malloc for libxml2 memory management by setting an environment variable:
# "default" here means "libxml2's default" which is system malloc
NOKOGIRI_LIBXML_MEMORY_MANAGEMENT=default
Benchmarks show that this setting will significantly improve performance, but be aware that the tradeoff may involve poorer memory management including bloated heap sizes and/or OOM conditions.
[CRuby] The libxml2 update fixes an encoding regression when push-parsing UTF-8 sequences. [#2882, upstream issue and commit]

Notes
Ability to opt into system malloc and free
Since 2009, Nokogiri has configured libxml2 to use ruby_xmalloc et al for memory management. This has provided benefits for memory management, but comes with a performance penalty.
Users can now opt into using system malloc for libxml2 memory management by setting an environment variable:
# "default" here means "libxml2's default" which is system malloc
NOKOGIRI_LIBXML_MEMORY_MANAGEMENT=default
Benchmarks show that this setting will significantly improve performance, but be aware that the tradeoff may involve poorer memory management including bloated heap sizes and/or OOM conditions.
Encoding objects may now be passed to serialization methods like #to_xml, #to_html, #serialize, and #write_to to specify the output encoding. Previously only encoding names (strings) were accepted. [#2774, #2798] (Thanks, @ellaklara!)
