Network compression between RS members

[Antonia_Tugores (Antònia Tugores)]

Hi,

network compression is just for client/server or also for replica set members?
We’re using v4.4

Thanks in advance.

Hi @Antonia_Tugores

Members and clients, they must also have compression enabled with a common compressor type.

See --networkMessageCompressors

mongod — MongoDB Manual

Or net.compression.compressors

Configuration File Options — MongoDB Manual

Thanks!
In fact, I was using net.compression.compressors but it seemed not to be working for the initial sync. Now I’ve been checking last 4.4.5 changelog and our problem was probably related to https://jira.mongodb.org/browse/SERVER-52919, included in 4.4.5.
