Description

This one has bugged me for a while - and in the interests of having Delphi 1
speed ..

On large projects (Delphi Win32 personality) - eg Ours has about 972 units
(at last count) spread over about 30 folders.

If you have the compiler dialog set to display and then press F9 to compile
(or shift-F9 to build), there is a 10-15 second delay before the compile
dialog appears.

On small projects e.g. less < 50 units - there is no noticeable delay.

It would be nice to have this < 1 second!

Myles.

Steps to Reproduce:

Case (a) - as expected (fast/no delay)
1. Have a large Win32 project handy to compile. Suggest > 500 units (all up).
2. Compiler it.
3. Close IDE.
2. Start IDE.
3. Turn on show compiler progress dialog.
4. Open project/project group - ensure have no forms visible - all in code editor state instead.
5. Compile using Ctrl-F9
6. Wait is about 1 second or less.

Case (b) - Slow
1. Have a large Win32 project handy to compile. Suggest > 500 units (all up).
2. Start IDE.
3. Turn on show compiler progress dialog.
4. Open project/project group.
5. Make changes to about 20 units in a variety of folders e.g spend 1/2 an hour editing - esp those not directly included in the project file.
It seems esp dependent on having the Form designer active or having being used in the session - the more it is used, or the more frames/forms active, the slower the time to show the compile dialog.

6. Compile using Ctrl-F9

7. Wait for upto 10-15 seconds for dialog to appear (CPU is typically at 100%)

Have you tried turning off AutoSave? Maybe this is what actually causes the delay...

I, too, had this problem, using the C++ personality. It became so bad that it took as much as full minute before the compile dialog even appeared. It was intolerable. I tried everything, including a total re-install of the BDS. In desperation, I tried this: 1. Create a new, empty project. 2. Add all your files from the old project. 3. It worked! Everything is back to FULL speed again. I am seeing it gradually get slower again as the days go by and I will just recreate the project file again when necessary.
