app/vmselect/netstorage: limit the size of metricNamesBuf to 32Kb in order to avoid slow path at Go runtime for allocating a byte slice of bigger size 
See 704401ffa0/src/runtime/malloc.go (L11)

This also reduces the average memory usage a bit for vmselect and single-node VictoriaMetrics
after the commit 508c608062

README.md

vmselect performs the following tasks:

  • Splits incoming selects to tasks for vmstorage nodes and issues these tasks to all the vmstorage nodes in the cluster.

  • Merges responses from all the vmstorage nodes and returns a single response.

The vmui directory contains static contents built from app/vmui package with make vmui-update command. The vmui page is available at http://<vmselect>:8481/select/<accountID>/vmui/.
