The R3load data itself is compressed (it's about 1/10 of the original size). There's no other compression used. Markus Daniyar Zhussupbayev 2 posts since Oct 18, 2009 Re: R3load socket compression Oct 8, 2010 6:29 PM Yes, if option "net" is used (dump files are written to disk) - then export is compressed 1/10. If I use option "socket" - there are no dump files. Parallel export/import of 1 TB database take ~5 hours. Bandwidth usage monitor shows load 580 Mb/s from 1Gb/s. It is ~250GB/hour. It seems that R3load process with "-socket" option doesn't compress data. Now I'm going to use parallel export/import with "net" option instead. Simple source DB export takes just 1 hour, that is export speed is 1TB/hour. It will create dumps with speed 100GB/hour. Transferring 100GB over 1Gb/s channel will take less than an hour. But may be there is a option, that can force R3load to use compression with "socket" option?

Not sure what you mean.
The R3load data itself is compressed (it's about 1/10 of the original size). There's no other compression used.
