I am using Debian Woody with the 2.4.19 Kernel on a AMD AthelonXP +2500 system. I am using the Promise driver downloaded and compiled from there website. I am getting about 3.3Meg/sec from the array to an EIDE disk (segate barracuda ATA). While from the Array to the Array I get about 4.1Meg/sec; copying 200G is an overnight plus job for sure. To me this is stupid slow, and I must be doing something wrong. Even if the Promise card is the slowest one available (3Ware, Promise, Adaptek) it can't really be *this* slow: this card should not even be on the market at this speed. All the while my system load average is about 1.5-2. Is this Linux? Does it really run this slow under Windows as well? Should I be using i2o or some other driver? Perhaps the array is just too large? PS: I get no errors, and the card is on it's own interrupt with a full 128MB cache. Thanks, Jason. -- Jason C. Leach IT Manager J.S. Thrower & Associates Ltd.
