Profiling
|
|
|
|
|
---------
|
|
|
|
|
|
|
|
|
|
Prepare `profile.data`:
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
zig build -Drelease-small=true && \
|
|
|
|
|
perf record --call-graph=dwarf \
|
|
|
|
|
zig-out/bin/turbonss-unix2db --passwd passwd --group group
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
Perf interactive:
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
perf report -i perf.data
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
Flame graph:
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
perf script | inferno-collapse-perf | inferno-flamegraph > profile.svg
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
For v2
|
|
|
|
|
------
|
|
|
|
|
|
|
|
|
|
These are desired for the next DB format:
|
|
|
|
|
- Compress strings with fsst.
|
|
|
|
|
- Trim first 4 bytes from the cmph headers.

Dependencies
|
|
|
|
|
------------
|
|
|
|
|
|
|
|
|
|
This project uses [git subtrac][git-subtrac] for managing dependencies. They
|
|
|
|
|
work just like regular submodules, except all the refs of the submodules are in
|
|
|
|
|
this repository. Repeat after me: all the submodules are in this repository.
|
|
|
|
|
So if you have a copy of this repo, dependencies will not disappear.
