largeNbDicts
|
|
=====================
|
|
|
|
`largeNbDicts` is a benchmark test tool
|
|
dedicated to the specific scenario of
|
|
dictionary decompression using a very large number of dictionaries.
|
|
When dictionaries are constantly changing, they are always "cold",
|
|
suffering from increased latency due to cache misses.
|
|
|
|
The tool is created in a bid to investigate performance for this scenario,
|
|
and experiment mitigation techniques.
|
|
|
|
Command line :
|
|
```
|
|
