bd0c6a095e docs/CHANGELOG.md: do not mention reduction in query duration 
There was a signficant refactoring in the code responsible for time series search,
so it can result in both speed ups and slow downs depending on used queries.

fd86a7dc1d lib/storage: time series search optimization according to production workload profiling 
Do not pass filter metric ids to getMetricIDsForTagFilter, since it has been appeared that this slows down
the function by multiple times when it finds big number of metricIDs (tens of millions).

c14dafce43 lib/promscrape: an attempt to reduce memory usage when vmagent scrapes targets with varying number of metrics 
Do not cache too big byte buffers and too big writeRequestCtx objects,
since it is cheaper to re-create them instead of wasting RAM for their caching.
