Hi,

after upgrading from version 4.61 to 5.0 i noticed a small increase of the executable file. Now, after upgrade from PB 5.10 Beta 1 to Beta 2 i noticed another large increase of the executable file.

My current newsreader project sizes are:
compiled with 5.1 Beta 1 = 823,7 KB
compiled with 5.1 Beta 2 = 907,9 KB

It is an increase of over 10%!

Best regards,
Uwe

That's wierd as the only changes are bug fixes on the canvas and IDE

Sorry, but i have to correct me: The differences are between Beta 1 and Beta 2.

May be you use RegExp ? We added UTC support for PCRE, may be it includes some big tables for conversion.

You are right, Fred. The mentioned project uses Regex. I checked some of my other projects with the following result:

Projects/Programs with Regex:
1. PB 5.1 size 268,4 PB 5.2 size 351,4
2. PB 5.1 size 317,2 PB 5.2 size 413,2
3. PB 5.1 size 268,4 PB 5.2 size 351,4
4. PB 5.1 size 142,3 PB 5.2 size 225,4
The average increase is 88,5 KB or 36%.

Projects/Programs without Regex:
5. PB 5.1 size 90,9 PB 5.2 size 92,5
6. PB 5.1 size 65,5 PB 5.2 size 68,3
The average increase is just 2,2 KB or 3%.

All sources have not been changed between both compilations.

Well, then I think this can't be avoided, or this bug won't be fixed: viewtopic.php?f=4&t=52534

Just to let you know, after changing all Regex relevant code i could reduce every project up to 200KB of size

Btw, most of the Regex stuff could be recoded very easy and now the performance is very much better.

Conclusion: Regex is convenient, but very slow...

It all depends of what you do, regexp are here to help which complex searching schemes.
