Bucket 0 – This is the current bucket its working on. How many buckets it needs to work on is set in the plotter configuration settings. I have messed around with this setting by setting it to 32, 64, and 256. No difference in overall plot speed. But, changes the RAM requirements drastically. 64 buckets needs double the RAM requirement of 128 buckets. 32 buckets needs double the RAM requirement of 64 buckets. 256, however, needs half of the RAM requirement of 128. You can see the pattern here. If someone is RAM limited, I could see how going to 256 may reduce your RAM requirements. It does…but you are also doubling the I/O requests on your temp drive. Use caution here.
