Anyone know if the size of your PKG file effects speed, or if its just number of triggers fireing and timers that are running....

I have a large PKG and wondered if deleting old triggers/alias that are no longer used would improve performance.

Thanks

I know that this was true in Zmud. The more settings you have the slower things go. However things actually firing has a greater effect on speed than things that are just sitting there.
The simple act of turning off your old triggers should improve things. Remember that everything is loaded into memory. That being the case...
If you reach that magic number where things start getting placed into the page file you are going to take a significant hit!

well this file isnt MASSIVE but it is a decent size. 2.7meg ish. so a fair lot of code whacked inside it

anyone know how much of an improvement deleting say 1/3 of my triggers in a 3meg package would make? would it be noticeable.

There's a simple answer - try it and see. Create a backup copy and delete them and see what happens. Could be a large effect, could be a small one.

Triggers that are not enabled should not have any impact on performance. CMUD uses database indexes and only indexes the currently active triggers (and other settings). So if the triggers are disabled, or if they are contained within disabled folders, then they shouldn't have any speed impact.

CMUD works very differently than zMUD in this case. zMUD didn't have any internal database indexes, so it was slower to lookup settings in memory. zMUD used a hash table, but this hash table contained *every* setting regardless of whether it was enabled or disabled.

Yes, everything is loaded into memory. But 2.7meg should be a very small percentage of your system memory. You can always run the Windows Task Manager and look at the memory usage to see if your system is paging to disk or not. On my system, for example, Firefox is typically using between 100 and 200 MB of RAM, while CMUD is only using 60MB or so.
