Subject: [pbs-devel] [PATCH proxmox-backup] datastore: use cached snapshot time string in path
Date: Wed, 3 Jul 2024 17:08:36 +0200 [thread overview]
Message-ID: <20240703150841.467740-1-g.goller@proxmox.com> (raw)
When getting the `full_path` of a snapshot we did not use the cached
time string. By using it we avoid a call to the super-slow libc strftime.
This has some minor performance improvements of circa 7%. That is ~100ms
on my datastore with ~5000 snapshots.
