lib/storage: increase the number of created time series in BenchmarkHeadPostingForMatchers in order to be on par with Promethues
...
The previous commit was accidentally creating 10x smaller number of time series than Prometheus
and this led to invalid benchmark results.
The updated benchmark results:

lib/storage: add BenchmarkHeadPostingForMatchers similar to the benchmark from Prometheus
...
See the corresponding benchmark in Prometheus - 23c0299d85/tsdb/head_bench_test.go (L52)
The benchmark allows performing apples-to-apples comparison of time series search
in Prometheus and VictoriaMetrics. The following article - https://www.robustperception.io/evaluating-performance-and-correctness -
contains incorrect numbers for VictoriaMetrics, since there wasn't this benchmark yet. Fix this.
Benchmarks can be repeated with the following commands from Prometheus and VictoriaMetrics source code roots:
- Prometheus: GOMAXPROCS=1 go test ./tsdb/ -run=111 -bench=BenchmarkHeadPostingForMatchers
- VictoriaMetrics: GOMAXPROCS=1 go test ./lib/storage/ -run=111 -bench=BenchmarkHeadPostingForMatchers
Benchmark results:

The first column (old) is for Prometheus, the second column (new) is for VictoriaMetrics.
As you can see, VictoriaMetrics outperforms Prometheus by more than 100x in almost all the test cases of this benchmark.
Prometheus was using 3.5GB of RAM during the benchmark, while VictoriaMetrics was using 400MB of RAM.

lib/storage: remove inmemory index for recent hour, since it uses too much memory
...
Production workload shows that the index requires ~4Kb of RAM per active time series.
This is too much for high number of active time series, so let's delete this index.
Now the queries should fall back to the index for the current day instead of the index
for the recent hour. The query performance for the current day index should be good enough
given the 100M rows/sec scan speed per CPU core.
