438a2e2abc Make sure setOldestVersion has work to do in bench 2024-02-23 14:41:05 -08:00
305c218888 Skip checking for partial key match if partial key len == 0
This saves instructions according to cachegrind
2024-02-23 14:27:20 -08:00
db60782c48 Use **self directly in insert 2024-02-23 14:09:04 -08:00
4f32ecc26e Make "begin" a template parameter to insert
cachegrind says this saves instructions
2024-02-23 14:00:55 -08:00
f84aa88202 Copy old node to new more efficiently
Presumably it's generating good code for the memcpy with a static size,
and hopefully also eliminating redundant stores
2024-02-23 13:31:05 -08:00
921da1cb3f Remove redundant code 2024-02-23 13:13:48 -08:00
14de4ee297 Specialize setChildrenParents for each node type
cachegrind says this increases the instruction count somehow. I'm not
sure what's going on there.

7136b5a450 Save more instructions in getOrCreateChild
Take advantage of the property that Node4 is a prefix of Node16
2024-02-23 12:39:24 -08:00
116c79d3de Optimize getOrCreateChild
Add fast path for if it exists

Avoid some unnecessary branches

Try to simplify some

aaf0283f66 Prefer getChild to getChildGeq in happy path
Saves instructions according to cachegrind

3a5db2d2ac Share some Node4/16 and Node48/256 implementations
This cuts down on the number of instructions (confirmed with
cachegrind). Also avoid initializing some memory unnecessarily.
