I realised that I may be able to work with a lower-powered CPU, but will find it difficult to work unless the replica server had high enough IOPS to handle all the disk I/O. :) thanks a lot, Shuvam ---- Cyrus Home Page: http://www.cyrusimap.org/ List Archives/Info: http://lists.andrew.cmu.edu/pipermail/info-cyrus/
