Peter Štibraný	4381b28c80	pkg/chunkenc: BenchmarkRead focuses on reading chunks (#1423 ) Previously BenchmarkRead asked for every single line from chunks to be returned. This causes a lot of unnnecessary allocations, which dominate the benchmark. Instead of counting bytes when reading, we now count size when generating data for logging speed. Another test was added to show that these two approaches are comparable. This change makes BenchmarkRead to report real time needed to decode chunks: name old time/op new time/op delta Read/none-4 86.2ms ± 0% 33.2ms ± 0% ~ (p=1.000 n=1+1) Read/gzip-4 255ms ± 0% 194ms ± 0% ~ (p=1.000 n=1+1) Read/lz4-4 121ms ± 0% 64ms ± 0% ~ (p=1.000 n=1+1) Read/snappy-4 119ms ± 0% 67ms ± 0% ~ (p=1.000 n=1+1) name old alloc/op new alloc/op delta Read/none-4 134MB ± 0% 0MB ± 0% ~ (p=1.000 n=1+1) Read/gzip-4 135MB ± 0% 0MB ± 0% ~ (p=1.000 n=1+1) Read/lz4-4 136MB ± 0% 1MB ± 0% ~ (p=1.000 n=1+1) Read/snappy-4 135MB ± 0% 0MB ± 0% ~ (p=1.000 n=1+1) name old allocs/op new allocs/op delta Read/none-4 491k ± 0% 3k ± 0% ~ (p=1.000 n=1+1) Read/gzip-4 491k ± 0% 3k ± 0% ~ (p=1.000 n=1+1) Read/lz4-4 491k ± 0% 3k ± 0% ~ (p=1.000 n=1+1) Read/snappy-4 491k ± 0% 3k ± 0% ~ (p=1.000 n=1+1) Decompression speed is now also more correct (esp.

Peter Štibraný	9979321c2a	Don't pool LZ4 readers that read big blocks.
