I wouldn't have wanted to write in capital letters.... I would have sworn not to have done.... Apologies for that really ..... Note taking mate. We didn't changed almost nothing than the sync param, for avoid modifying the most we could the default config of ZFS. We thought it could perhaps be the most stable config and we have not disk space problems so... Apart of that, for avoid load coming from compression/decompression.... although we have lots of cpu too..... Thanks a lot Bob :) Cheers, El 2022-04-06 22:18, Bob Friesenhahn escribió: > ATENCION > ATENCION > ATENCION!!! Este correo se ha enviado desde fuera de la organizacion.

WE HAVE NOT TOUCHED COMPRESSION.... There seems to be a problem with your caps-lock key. Since it seems that you said that you are using maildir for your mail server, it is likely very useful if you do enable even rather mild compression (e.g. lz4) since this will reduce the write work-load and even short files will be stored more efficiently.
