## What changes were proposed in this pull request? When ChunkBuffer allocates heap buffer UnsafeByteOperations.unsafeWrap() returns a BoundedByteString with a backing array, enabling a single System.arraycopy into the gRPC/Netty wire buffer instead of the slow byte-by-byte NioByteString path for direct buffers. ## What is the link to the Apache JIRA https://issues.apache.org/jira/browse/HDDS-15592 ## How was this patch tested? Benchmark run on m3 mac/ARM with 14 cores producing the following results: --- scaling summary writeSize=4096KB --- threads | direct MB/s | heap MB/s | heap/direct | direct eff. | heap eff. ---------|--------------|--------------|------------|------------|------------ 1 | 5,098.0 | 5,624.6 | 1.10x | 1.00 | 1.00 2 | 9,326.6 | 10,766.9 | 1.15x | 0.91 | 0.96 4 | 17,293.4 | 18,886.2 | 1.09x | 0.85 | 0.84 7 | 24,220.6 | 27,652.1 | 1.14x | 0.68 | 0.70 14 | 25,092.3 | 31,294.6 | 1.25x | 0.35 | 0.40 28 | 26,017.8 | 28,899.0 | 1.11x | 0.18 | 0.18 42 | 27,288.1 | 30,836.3 | 1.13x | 0.13 | 0.13 --- scaling summary writeSize=3072KB --- threads | direct MB/s | heap MB/s | heap/direct | direct eff. | heap eff. ---------|--------------|--------------|------------|------------|------------ 1 | 6,441.7 | 7,407.9 | 1.15x | 1.00 | 1.00 2 | 12,718.8 | 14,405.9 | 1.13x | 0.99 | 0.97 4 | 24,420.3 | 27,779.9 | 1.14x | 0.95 | 0.94 7 | 39,524.5 | 44,928.1 | 1.14x | 0.88 | 0.87 14 | 47,319.0 | 58,903.6 | 1.24x | 0.52 | 0.57 28 | 41,418.1 | 50,173.2 | 1.21x | 0.23 | 0.24 42 | 39,672.7 | 50,588.1 | 1.28x | 0.15 | 0.16 --- scaling summary writeSize=2048KB --- threads | direct MB/s | heap MB/s | heap/direct | direct eff. | heap eff. ---------|--------------|--------------|------------|------------|------------ 1 | 5,092.0 | 5,753.0 | 1.13x | 1.00 | 1.00 2 | 9,601.4 | 10,889.3 | 1.13x | 0.94 | 0.95 4 | 17,719.7 | 18,854.6 | 1.06x | 0.87 | 0.82 7 | 24,087.2 | 27,649.2 | 1.15x | 0.68 | 0.69 14 | 26,875.0 | 30,787.4 | 1.15x | 0.38 | 0.38 28 | 26,819.5 | 30,021.1 | 1.12x | 0.19 | 0.19 42 | 27,593.0 | 30,644.9 | 1.11x | 0.13 | 0.13 --- scaling summary writeSize=1024KB --- threads | direct MB/s | heap MB/s | heap/direct | direct eff. | heap eff. ---------|--------------|--------------|------------|------------|------------ 1 | 5,059.7 | 5,682.8 | 1.12x | 1.00 | 1.00 2 | 9,736.1 | 10,943.2 | 1.12x | 0.96 | 0.96 4 | 17,766.6 | 19,292.5 | 1.09x | 0.88 | 0.85 7 | 24,588.8 | 28,444.3 | 1.16x | 0.69 | 0.72 14 | 27,671.9 | 31,524.6 | 1.14x | 0.39 | 0.40 28 | 26,259.2 | 30,340.7 | 1.16x | 0.19 | 0.19 42 | 27,058.7 | 30,937.3 | 1.14x | 0.13 | 0.13 --- scaling summary writeSize=512KB --- threads | direct MB/s | heap MB/s | heap/direct | direct eff. | heap eff. ---------|--------------|--------------|------------|------------|------------ 1 | 4,843.5 | 5,502.6 | 1.14x | 1.00 | 1.00 2 | 9,165.2 | 10,428.1 | 1.14x | 0.95 | 0.95 4 | 17,641.7 | 19,249.4 | 1.09x | 0.91 | 0.87 7 | 24,383.0 | 27,974.6 | 1.15x | 0.72 | 0.73 14 | 27,056.3 | 30,301.9 | 1.12x | 0.40 | 0.39 28 | 27,436.6 | 30,545.3 | 1.11x | 0.20 | 0.20 42 | 27,118.8 | 30,685.3 | 1.13x | 0.13 | 0.13 --- scaling summary writeSize=256KB --- threads | direct MB/s | heap MB/s | heap/direct | direct eff. | heap eff. ---------|--------------|--------------|------------|------------|------------ 1 | 4,985.1 | 5,655.3 | 1.13x | 1.00 | 1.00 2 | 9,738.0 | 10,646.6 | 1.09x | 0.98 | 0.94 4 | 17,132.0 | 19,142.1 | 1.12x | 0.86 | 0.85 7 | 24,196.4 | 28,211.3 | 1.17x | 0.69 | 0.71 14 | 27,048.4 | 31,631.4 | 1.17x | 0.39 | 0.40 28 | 27,276.7 | 28,319.7 | 1.04x | 0.20 | 0.18 42 | 26,891.1 | 30,444.4 | 1.13x | 0.13 | 0.13 -- This is an automated message from the Apache Git Service.
