The JACoW collaboration considers the performance of the website to be very important for users, considering the wide range of users around the world and the range of resources available to them. JACoW papers should display quickly, and a key factor in the speed with which a page is displayed is the size and complexity of the file. Typically, each page should display in 5/N seconds, where N is the processor speed in GHz. Graphics and illustrations can be painfully slow if the files are too big or complex. See the section on Graphics for dealing with large, detailed images.
The four types of field coagula are "cuplump", "treelace", "smallholders’ lump" and "earth scrap". Each has significantly different properties.  Some trees continue to drip after the collection leading to a small amount of "cup lump" that is collected at the next tapping. The latex that coagulates on the cut is also collected as "tree lace". Tree lace and cup lump together account for 10–20% of the dry rubber produced. Latex that drips onto the ground, "earth scrap", is also collected periodically for processing of low-grade product.
