I had the whole week off anyhow; my baby girl was being born. (Add Bailey Joanna Peters to the user's list, age 0.02 years. ;^) I experienced several lockups during periods of disuse with the 2842, replacing the 1520 prevented the lockups. I've heard that updating to -stable or -current will solve this problem. True? In order to benchmark the performance, I decided to build an identical kernel using my 1520 and the 2842. The kernel build times were nearly identical. I should interpret this data as: 1- Both host adapters can max out my (14 ms) SCSI disk, but the 2842 will give me lower overall system load; I've spent my money wisely. 2- The 2842 is no faster than the 1520; I've just wasted $250. 3- Something else that hasn't penetrated the fatigue poinsons building up in my brain. ;^) I believe the answer should be #1.
