Lag or latency in Second Life can be reduced by residents diligently removing resize/recolor scripts from hair, shoes, boots, jewelry, and other attachments whenever possible. Most apparel or attachments that enable the user to resize or recolor the item include scripts which, once used, can be removed. This reduces Sim latency and can provide the user with a better real-time experience in Second Life.
deleting scripts, make a copy of the original script enabled item. Most
vendors provide items like shoes and hair with "Modify/Copy/No Transfer"
permissions. This allows the user to make a copy of the original as a
backup in case you ever need to go back and resize/recolor/reconfigure
the object. Unfortunately some vendors provide their products with "No
Copy/Transfer" permissions which makes it impossible for the user to
make a backup copy. In the case of "No Copy" items the owner is forced
to decide between keeping the script functionality or reducing the lag
induced by the item. Vendors who do not provide copyable items should read my Request to Second Life Vendors.
a backup copy has been made (if possible) and the product has been
resized or otherwise configured to taste, you can delete the script(s).
This is usually accomplished by simply clicking a "Delete", "Delete
Scripts", "Remove", or somesuch button in the item's resize/configure
menu. Most vendors will include a notecard with specific instructions
for how to remove any scripts. Often this entails issuing a command on a
channel the item is listening on. For instance, scripts in Kalnins shoes can be removed by issuing the command "/76 deletescripts" in local chat.
