Supplementary Figure 3: KLB performance comparison for local vs. network data storage
From: Efficient processing and analysis of large-scale light-sheet microscopy data
Comparison of KLB read and write speeds on a local data drive versus a data drive mounted over the network (using a 10 Gb/s glass fiber connection). Speeds are comparable since most of the time is spent on data compression and decompression, respectively, and physical disk access introduces relatively little overhead. Moreover, most modern operating systems and RAID hardware improve I/O performance by caching and by using dedicated processors that avoid load on primary CPUs. Thus, while some blocks are compressed or decompressed others are written or read, respectively, masking I/O costs. All data points are averages based on n = 5 iterations of the benchmark.
