Are you sure there's an order of magnitude of difference between real and virtualized hardware? Does redis actually deliver 100k operations _per core_? (I thought it is supposed to be per machine, because memory bandwidth is a bottleneck or something) Can you point to the relevant benchmarks, please. I am interested to know how big of a difference there is. Maybe redis on Xen performs not bad after all, considering that 2.2 GHz Athlon 64 3700+ (single core CPU, circa 2005) is lower powered than what is considered server box today.

Yes I'm sure. from 100k to 140k operations per second in any new computer (not server or special hardware) you can buy today as a desktop everywhere. Check the Redis benchmark page on google code to see this numbers, but I want to show you how Redis performs in an EEE PC 701: PING: 7942.81 requests per second PING (multi bulk): 7861.64 requests per second MSET (10 keys, multi bulk): 6435.01 requests per second SET: 5698.01 requests per second GET: 8183.31 requests per second INCR: 9074.41 requests per second LPUSH: 8710.80 requests per second LPOP: 8583.69 requests per second SADD: 8396.31 requests per second SPOP: 8123.48 requests per second cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 13 model name : Intel(R) Celeron(R) M processor 900MHz stepping : 8 cpu MHz : 630.029 cache size : 512 KB Note that it is clocked at 630 Mhz. I don't know exactly but the PC you mention can not deliver less than 50k operations per second.
