benchfn used to rely on mem.h, and util, which in turn relied on platform.h. Using benchfn outside of zstd required to bring all these dependencies. Now, dependency is reduced to timefn only. This required to create a separate timefn from util, and rewrite benchfn and timefn to no longer need mem.h. Separating timefn from util has a wide effect accross the code base, as usage of time functions is widespread. A lot of build scripts had to be updated to also include timefn. |

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)
