System takes long time to Save/Activate using SFP Form Builder

We are planning to customize the Travel Expense PDF Form – PTRV_EXPENSE_FORM in ECC 6.0 using transaction SFP – FORM BUILDER (ABAP Workbench). As the initial step we copied it into Z form and started the changes. Here is the problem: Even for a small change on the Layout, system is taking long time to complete the process.

For example:

For Saving the changes: 6 to 7 minutes

For Activating the changes: 12 to 13 minutes.

On the server side :

we are on ECC 6.0, SAP NW04s SP 9 for EA-HR

ADOBE LiveCycle Designer 7.1 (Patch 3 applied).

On client machine :

we have SAP GUI 640 Patch Level 21,

ADOBE Reader 7.0.9.

Client machine has 1 GB RAM & 40 GB Hard Drive.

Thanks in Advance for the quick reply.
