Subject: SAS VMS performance problem
Running on a DEC Alpha 4000 5/300, we 've got big performance problem
when working with large datasets.
We would like to compare a file with 10,000,000 records with another one
containing also about 10,000,000 records. The compared field is a
As a first test, we tried to the process with only 1,000,000 records in
each file: Elapsed time 9 hours, cpu time 15 minutes.
We are nearly the only user of this machine. So most of the ressources
are not shared with other processes.
Just to have a point of comparison, we did the same test on a PC PII
233Mhz local hard disk Win NT: 5 minutes !!!!
Any idea to tune SAS and/or Alpha parameters (hardware ?) ?
