Hi,
do you know if performing offline compaction from time to time in production environment can increase performance besides reducing disk occupation? If yes could you also explain why you gain performance?
Thank you,
Stefano
Hi Stefano,
this depends on the persistence you use. While on TarMK (given enough RAM do use mmap) the performance impact is quite small, it can be pretty huge on MongoMK because there the storage is structured differently. Holding all the (unused) versions impacts performance due to the amount of data transferred over the network or due to inefficient use of Mongo indexes and storage/RAM.
HTH,
Jörg
