Subject: [pve-devel] [PATCH manager 0/4] gui/api performance improvements
Date: Fri, 5 Sep 2025 13:51:58 +0200 [thread overview]
Message-ID: <20250905120627.2585826-1-d.csapak@proxmox.com> (raw)
this series fixes a series of bad patterns in our api/gui code,
especially some O(n^2) code regarding resource count (vms/storages/etc.)
note that the api change is only a current stop-gap workaround and aaron
is working on making that code not necessary at all, but for now this
should be good.
The overall perforamnce improvement i see on my local test cluster with
~10000 vms is from
API ~22s + GUI ~8.5s
to
API 500ms + GUI 500ms
which is a ~30x speedup (since it's mostly quadratic code that is
removed, this is more noticable the more resources there are ofc)
Dominik Csapak (4):
API2Tools: rrd: remove O(n^2) lookup for keys
ui: fix O(n^2) calculations when loading /cluster/resources
ui: resource tree: improve performance on initial update
ui: resource tree: fix change detection
