Code search latency improvements
Gary Tong
Hello all,
In our Chrome developer productivity surveys, Code Search has been frequently cited as an area that needs improvement. Specifically, the asks have been:
Latency improvements
More cross references
Faster indexing
Fewer duplicate results
We’re excited to announce that, through the fantastic work of the Git-on-Borg team, latency for both history and blame operations have been significantly reduced. The most recent changes, released over the month of April, brought P90 latencies down from 10+ seconds to less than 2:
Loading blame on DEPS is actually pretty fast now! (this also works on Code search but it’s not linkable)
We’ve also partnered with the Git-on-Borg team to set up SLOs for code search availability and latency going forward. They are:
History and blame availability > 99.5%
History latency < 1s at P50 and < 7s at P90 (because it can take a long time to fetch history for files that haven’t been touched in years)
Blame latency < 7s at P90
The SLOs are viewable on the Chrome Dev Infra SLO (Googlers only) dashboard.
Huge thanks to the Git-on-Borg team for all their work here! Making history and blame quick for Chromium’s codebase is not an easy task, and there were significant technical challenges to overcome to deliver these improvements. We’re also making progress in the other areas, and will share more as it lands.
Best,
Gary on behalf of PDEIO
