app/vmselect/netstorage: improve the speed of queries over big number of time series on multi-CPU system 
Reduce inter-CPU communications when processing the query over big number of time series.
This should improve performance for queries over big number of time series
on systems with many CPU cores.

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/.
