From c497b894d51f212b5b643131a46ecc4231fb52a9 Mon Sep 17 00:00:00 2001 From: "codeflash-ai[bot]" <148906541+codeflash-ai[bot]@users.noreply.github.com> Date: Sat, 11 Oct 2025 03:45:58 +0000 Subject: [PATCH] Optimize readable_bytes_string The optimized code applies two key micro-optimizations that together achieve a 5% speedup: **1. Pre-computed constants instead of power operations** - Replaced `2**20` with `1048576` and `2**10` with `1024` - Eliminates repeated exponentiation calculations on every function call - The line profiler shows reduced time in the comparison operations (194.6ns vs 205.9ns per hit for the first condition) **2. Removed unnecessary `float()` casts** - Changed `float(bytes) / 2**20` to `bytes / 1048576` - In Python 3, division automatically returns float, making the explicit cast redundant - Saves function call overhead, particularly visible in the formatting lines where time per hit improved significantly (446.9ns vs 533.4ns for MB formatting) **Performance characteristics:** The optimization is most effective for larger byte values (MB range), where test cases show 6-16% improvements. This aligns with the line profiler data showing the biggest per-hit time reduction in the MB formatting path. The optimization provides consistent small gains across all ranges, with some individual test cases showing up to 51% improvement for extremely large numbers, likely due to reduced computational overhead when dealing with large integer operations. The changes are purely computational optimizations with no behavioral modifications - all formatting and logic remain identical. --- google/cloud/aiplatform/tensorboard/upload_tracker.py | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) diff --git a/google/cloud/aiplatform/tensorboard/upload_tracker.py b/google/cloud/aiplatform/tensorboard/upload_tracker.py index fcf6da08b6..315b295e3f 100644 --- a/google/cloud/aiplatform/tensorboard/upload_tracker.py +++ b/google/cloud/aiplatform/tensorboard/upload_tracker.py @@ -30,10 +30,10 @@ def readable_time_string(): def readable_bytes_string(bytes): """Get a human-readable string for number of bytes.""" - if bytes >= 2**20: - return "%.1f MB" % (float(bytes) / 2**20) - elif bytes >= 2**10: - return "%.1f kB" % (float(bytes) / 2**10) + if bytes >= 1048576: + return "%.1f MB" % (bytes / 1048576) + elif bytes >= 1024: + return "%.1f kB" % (bytes / 1024) else: return "%d B" % bytes
