Subject: immutable: further loosen the performance-regression test to allow up to 45 reads
X-Git-Url: https://git.rkrishnan.org/vdrive/%5B/%5D%20/somewhere?a=commitdiff_plain;h=7adf905b9f468b8e71599fbbc2097e77cb61cb0c;p=tahoe-lafs%2Ftahoe-lafs.git

immutable: further loosen the performance-regression test to allow up to 45 reads
This does raise the question of if there is any point to this test, since I apparently don't know what the answer *should* be, and whenever one of the buildbots fails then I redefine success.

But, I'm about to commit a bunch of patches to implement checker, verifier, and repairer as well as to refactor downloader, and I would really like to know if these patches *increase* the number of reads required even higher than it currently is.
