Nick Hill a258cd6f42 Optimize Hpack and AsciiString hashcode and equals (#8902) ... Motivation: While looking at hpack header-processing hotspots I noticed some low level too-big-to-inline methods which can be shrunk. Modifications: Reduce bytecode size and/or runtime operations used for the following methods: PlatformDependent0.equals(byte[], ...) PlatformDependent0.equalsConstantTime(byte[], ...) PlatformDependent0.hashCodeAscii(byte[],int,int) PlatformDependent.hashCodeAscii(CharSequence) Result: Existing benchmarks show decent improvement Before Benchmark (size) Mode Cnt Score Error Units HpackUtilBenchmark.newEquals SMALL thrpt 5 17200229.374 ± 1701239.198 ops/s HpackUtilBenchmark.newEquals MEDIUM thrpt 5 3386061.629 ± 72264.685 ops/s HpackUtilBenchmark.newEquals LARGE thrpt 5 507579.209 ± 65883.951 ops/s After Benchmark (size) Mode Cnt Score Error Units HpackUtilBenchmark.newEquals SMALL thrpt 5 29221527.058 ± 4805825.836 ops/s HpackUtilBenchmark.newEquals MEDIUM thrpt 5 6556251.645 ± 466115.199 ops/s HpackUtilBenchmark.newEquals LARGE thrpt 5 879828.889 ± 148136.641 ops/s Before Benchmark (size) Mode Cnt Score Error Units PlatformDepBench.unsafeBytesEqual 4 avgt 10 4.263 ± 0.110 ns/op PlatformDepBench.unsafeBytesEqual 10 avgt 10 5.206 ± 0.133 ns/op PlatformDepBench.unsafeBytesEqual 50 avgt 10 8.160 ± 0.320 ns/op PlatformDepBench.unsafeBytesEqual 100 avgt 10 13.810 ± 0.751 ns/op PlatformDepBench.unsafeBytesEqual 1000 avgt 10 89.077 ± 7.275 ns/op PlatformDepBench.unsafeBytesEqual 10000 avgt 10 773.940 ± 24.579 ns/op PlatformDepBench.unsafeBytesEqual 100000 avgt 10 7546.807 ± 110.395 ns/op After Benchmark (size) Mode Cnt Score Error Units PlatformDepBench.unsafeBytesEqual 4 avgt 10 3.337 ± 0.087 ns/op PlatformDepBench.unsafeBytesEqual 10 avgt 10 4.286 ± 0.194 ns/op PlatformDepBench.unsafeBytesEqual 50 avgt 10 7.817 ± 0.123 ns/op PlatformDepBench.unsafeBytesEqual 100 avgt 10 11.260 ± 0.412 ns/op PlatformDepBench.unsafeBytesEqual 1000 avgt 10 84.255 ± 2.596 ns/op PlatformDepBench.unsafeBytesEqual 10000 avgt 10 591.892 ± 5.136 ns/op PlatformDepBench.unsafeBytesEqual 100000 avgt 10 6978.859 ± 285.043 ns/op		2019-03-08 06:55:32 +01:00
