I have built a test machine to explore the possibility of replacing some expensive RS6000/AIX machines with Intel Linux. The machine is: Intel Pentium II 350 MHz. 128 MB SDRAM 1 8GB IDE HD 1 4GB IDE HD Aha2940UW SCSI Card 1 9GB Seagate Wide SCSI Drive most improtantly, Linux 2.2.1 kernel on a Slackware 3.6 base
This machine will be splitting DB2 flat files for a living. That's pretty much all it will do. The datasets range in size from a couple hundred K to 850 MB in size. The data are all on the SCSI drive at present, and plans call for additional drives on this SCSI chain later on. I am running a home made C application which does the job of sed and awk in that it reads in the dataset file and splits it into files according to information in the first field of each record, along with an assortment of error checking and logging. So to boil it down, this machine needs to be able to manage many thousands of file writes and reads very quickly. It already competes evenly with a dual processor RS6000, but the boss would like to see just a little bit more before we make a formal pitch.
I realize I have to improve the disk situation, but can you recommend any specific things to tweak in the kernel that might push this box just a tad faster?
