I think I'll give this a try on my redundent mirror server at work. I'd be curious to see how gjournal performs with the journal on a battery backed ram disk like the gigabyte i-RAM: http://www.giga-byte.com/Products/Storage/Products_Overview.aspx?ProductID=2180&ProductName=GC-RAMDISK It seems like that could reduce or eliminate many of the performance issues in practice. -- Brooks
