Op Amp model slowing simulation times - PC73530

All,

I'm having an issue in using the Spice model for component PC73530 in my circuit. My circuit seems to operate at extremely fast speeds until I add in this model. Since I have several of these Op Amp components in my circuit, its slows my circuit simulation down to a couple of minutes.

The model lib is as follows:

*SRC=TL084T;TL084T;Opamps;TI-"TLxxx";
*SYM=TIOPAMP
*pinout DIL14 3 2 4 11 1;5 6 4 11 7;10 9 4 11 8;12 13 4 11 14
*pinout SO14 3 2 4 11 1;5 6 4 11 7;10 9 4 11 8;12 13 4 11 14
*pinout FK20 4 3 6 16 2;8 9 6 16 10;14 13 6 16 12;18 19 6 16 20
* TL084 Opamp "MACROMODEL" SUBCIRCUIT
* (REV N/A) SUPPLY VOLTAGE: +/-15V
* CONNECTIONS: NON-INVERTING INPUT
* | INVERTING INPUT
* | | POSITIVE POWER SUPPLY
* | | | NEGATIVE POWER SUPPLY
* | | | | OUTPUT

You need to share your circuit, complete or a representative one. Just looking at model it would not be possible to comment about simulation time etc.
