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 :
largeNbDicts [Options] filename(s)
Options :
-r : recursively load all files in subdirectories (default: off)
-B# : split input into blocks of size # (default: no split)
-# : use compression level # (default: 3)
-D # : use # as a dictionary (default: create one)
-i# : nb benchmark rounds (default: 6)
--nbDicts=# : set nb of dictionaries to # (default: one per block)
-h : help (this text)
