For a same code to run proc model, why SAS 9.4 runs for 7 mintues while SAS 9.3 spends just 1 second?

[mht]

Dear folks,

I need a help for a problem running proc model. For a same code and a same dataset, my SAS 9.4(TS1M2) runs for 7 mintues while SAS 9.3(TS1M0) runs for just 1 second. Anybody can tell me why? Is it a bug to SAS 9.4 proc model? Since my institution is no longer supporting SAS 9.3, I am forced to use SAS 9.4 now and hence I really need this problem solved. Thank you and look forward to your help.

My computer is 64 bit Windows 7 professional and SAS 9.3. 9.4 are both 64 bit.

I attach in this post the simple code and dataset I used to test. You can try SAS 9.3 and SAS 9.4 to see my problem.

Look at the configuration:

MEMSIZE and other memory-related options in SAS

location of WORK and UTILLOC

Use OPTIONS FULLSTIMER in both environments to get a more specific log regarding where time is spent.
