Most people know that CasperVend uses only one script in all its vendor units and dropboxes. But how important is this, really?
Script Time
A region runs at approximately 45 frames per second when it's not lagged. This allows roughly 22ms *total* script time per region.
CasperVend vendors run at roughly 0.001 - 0.002ms of script time per frame. This means you could theoretically have 11,000 of our vendors rezzed without experiencing lag.
Of course, if you have other scripts on the region, they will be taking up script time, so you need to check exactly how much script time you have to use.
Script Memory
Another factor is script memory. A simulator has 256mb of memory, and each of our vendors uses 64kb. This means that we would run out of memory after 4096 vendors were rezzed, so that is our actual limit.
In order to properly calculate how many CasperVend vendors you can rez before you see any lag, go to:
World -> Region/Estate -> Debug -> Get Top Scripts. Refresh this a few times, and note the *maximum* number at the top, for example, mine says:
"539 scripts taking a total of 1.685ms."
Mutiply the script count by 64kb and you have the rough memory usage - in my case, it's 34496kb (or 33mb), so I have 223mb available to use - enough for around 3,500 vendors.
Subtract the script time from 22 and you have the amount of script time you have available to play with. In my case I have 20.315ms available, which is easily enough for the 3,500 vendors (it could support 20,000 of them).
How many vendors can I run without causing lag?
We rezzed vendors from these companies and left them for 30 minutes (for the script time to settle). Results:
| System | Script count (multivendors) | Script time | Script mem | Max # of vendors with no lag |
|---|---|---|---|---|
| HippoVend | 10 | 0.016 | 655kb | 400 |
| Alika | 3 | 0.002 | 197kb | 1330 |
| BSM | 2 | 0.003 | 131kb | 2001 |
| CasperVend | 1 | 0.001 | 66kb | 3971 |
