RFC: added performance tests for sparse getindex + a README file #7177
Conversation
Cc @staticfloat |
I ran the sparse performance tests for Julia 0.2.1, 0.3 before PR #7131 and after. Here the results: Interestingly, performance decreased in many tests from 0.2.1 to 0.3-pre-PR, even though the getindex methods did not change! (why?) PR#7131 increased performance in all but 3 tests compared to 0.3-pre-PR. They are all for small-ish matrices of 1000x1000. I'll have a look at those. |
#6112 is tracking the performance regressions. Best to continue the performance regression part of the discussion there. |
- `sort` various sorting algorithms | ||
- `spell` an implementation of a spell corrector | ||

I'd round out these descriptions a bit more. Something along the lines of:

Thanks @staticfloat, README is updated. |

RFC: added performance tests for sparse getindex + a README file
In PR #7131 @ViralBShah suggested that I should add the
getindex
performance test toperf/
. Here a tidied up version of https://gist.github.com/mauro3/7f01931b5f25d7b397af.Questions:
README.md
as I tried to figure out howperf/
works. Maybe this could be useful? It will need a read.codespeed
