Chimera does not have any fixed amount of memory allocated. It will use whatever is available. If you load large molecular systems (100,000 atoms) or large volume data sets (> 100 Mbytes) your computer may start swapping (transfering data back and forth to disk because it does not fit in memory). That can dramatically slow down any computation by factors of 10 or 100. The only real solution is to use a machine with more memory, or load smaller systems in Chimera. Are you working with molecules or volume data? There are tricks to reducing the data size depending on the type of data. Tom
