...it would be interesting to test this in Xen. AFAIK, the only extensive use of compression is with Transcendent Memory ("tmem"), so learning about tmem would be a useful side-effect. Thanks, Dan http://driverdev.linuxdriverproject.org/pipermail/devel/2011-April/015113.html From: Zeev Tarantov <zeev.tarantov at gmail.com> Google''s Snappy data compression library is a faster alternative to LZO, optimized for x86-64. On compressible input it compresses ~2.5x faster than LZO and decompresses ~1.5-2x faster than LZO. On incompressible input, it skips the input at 100x faster...

I've posted this before being subscribed but was thwarted by moderation. I have a new UPS, actual manufacturer unknown. It comes with USB and serial connections, and a CD with windows software and some old unix software for serial support only. I'm using pretty much bleeding edge linux, and I want to avoid rs-232 if possible. Am I hopelessly naive? This is what lsusb says: Bus 006
