Helix Core Server Administrator Guide: Fundamentals (2019.2)
Use patterns
Helix server usage can affect performance. Usage patterns can have a direct effect on performance:
- The depot filenames are the
leading portion of the key in several important
db.*
files, such asdb.rev
,
, anddb.revhx
db.integed
. As the length of paths to depot filenames increase, performance decreases. We recommend short names when possible. - Rather than frequent creation of full branches:
- Consider task streams. A task stream is a lightweight short-lived stream that only promotes edited files to the repository. See p4 stream.
- If you are not using task streams, consider branching only the subset of files needed for a given bug fix.
- Consider fixing multiple bug fixes on a single branch.
TipThe frequent creation of full branches increases the amount of metadata. This results in more levels within the
db.*
file B-trees, more key comparisons, and more I/O requests to traverse to the leaf pages. Also, reading and writing large amounts of metadata might affect the filesystem cache to the detriment of other Helix server tasks.
