    v40 v41  
    77In late 2010 Kyle Markley did some benchmarking of what were then the release candidates for Tahoe-LAFS v1.8.0. This helped us catch two major performance regressions in Brian's New Downloader and helped make Tahoe-LAFS v1.8.0 into an excellent new release (see epic ticket #1170 for mind-numbing details). Kyle also contributed code for his benchmarking scripts (in Perl), but nobody to my knowledge has yet tried to re-use that script.

    2020We also experimented with different segment sizes and immutable uploader pipeline depths, and the results tentatively confirmed that the current segment size (128 KiB) and immutable uploader pipeline depth (50,000 B) were better on both of Kyle's networks than any of the alternatives that Kyle tried.
