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 ==
|
||
|
|
