>          Issue Type: Bug
>    Affects Versions: 2.1
>            Reporter: Ksenia Rybakova

> The following experiment was done to compare logical vs physical caches witn PDS:
> - CacheRandomOperation benchmark was used to load data into caches
> - Number of loaded entries 10M per cache
> - All caches are atomic: 10 logical caches in 1 group vs 10 physical caches
> - walHistorySize =2
> - One default memory policy, memory config is default as well
> Configs are attached.
> ||10 logical caches in 1 group|| 10 physical caches ||Comments||
> ||Total size of work/db/127_0_0_1*| |Among all hosts|
> |23.6G|28.6G|Mainly because total size of partitions files (part-xxxx.bin) in "physical" case is bigger. In "phisical" case index.bin is one per cache while in "logical" case is one per group, but it's size is 16Kb so it doesn't make any difference.|
> ||Total size of work/db/wal/archive| |Among all hosts|
> |86.7G|63.6G|In "physical" case archive has more files.|
> ||Total size of work/db/wal/127_0_0_1*| |Among all hosts|
> |7.6G|7.6G| |
> The size difference should be investigated, currently reason is unclear.
