Here are some numbers from the benchmark:

Config: NoGc, Time: 25.9836
Config: OnFinishGc, Time: 49.012
Config: 100msPeriodicGc, Time: 45.9856
Config: 1000msPeriodicGc, Time: 40.3094

```
(TOOLCHAIN) mtomic@poso:~/memgraph/build_release$ tests/benchmark/storage_v2_gc --num-threads 7
Config: NoGc, Time: 20.4256
Config: OnFinishGc, Time: 39.6669
Config: 100msPeriodicGc, Time: 30.7956
Config: 1000msPeriodicGc, Time: 35.128
```
It is not that bad if there is a core dedicated to doing garbage collection.

Initial version of storage v2
...
Summary:
Initial implementation of new storage engine. It implements snapshot isolation
for transactions. All changes in the database are stored as deltas instead of
making full copies. Currently, the storage supports full transaction
functionality (commit, abort, command advancement). Also, support has been
implemented only for vertices that have only labels.
