The code that is there to run some unit tests on some internal features was moved to tests/unit. Ideally it should be buildable from the main makefile though this is not yet the case. The code that is kept for experimentation purposes (hashes, syscall optimization etc) as well as some captures of the results was moved to tests/exp. A few totally obsolete files which couldn't build anymore and were not relevant to current versions were removed.

These are the result of tests conducted to determine efficacy of hashing
|
|
algorithms and avalache application in haproxy. All results below were
|
|
generated using version 1.5. See the document on hashing under internal docs
|
|
for a detailed description on the tests the methodology and interpretation
|
|
of the results.
|
|
|
|
The following was the set up used
|
|
|
|
(a) hash-type consistent/map-bases
|
|
(b) avalanche on/off
|
|
(c) balanche host(hdr)
|
|
(d) 3 criteria for inputs
|
|
- ~ 10K requests, including duplicates
|
|
- ~ 46K requests, unique requests from 1 MM requests were obtained
|
|
- ~ 250K requests, including duplicates
|
|
(e) 17 servers in backend, all servers were assigned the same weight
|
|
|
|
The results can be interpreted across 3 dimensions corresponding to input
|
|
criteria (a)/(b) and (d) above
|
|
|
|
== 10 K requests ==
|
|
|
|
=== Consistent with avalanche ===
