Hi, We are running a SAS 9.3 grid and we are running into a very similar issue. The original setting for the ulimits were 1024. We changed it to the recommended 350000 (based on http://support.sas.com/kb/38/040.html) and we see a significant decrease in throughput. So to test a few more values, we set the ulimit at 10240 ( 10 times the original value) and there was no benefit whatsoever. What is the recommended ulimit settings ? Any help would be appreciated! Thanks JP
