You can download the chainsaw bundle for your platform and modify the .bat file to change the -Xms and -Xmx settings to give the VM more memory.
Re: application-wide cyclic buffer value Cyclic buffering is a per-tab setting and is enabled by default. Setting the cyclic buffer to X means for each tab, only the most recently received X events will be held in memory. Disabling cyclic buffering means you will hold all received events (and eventually run out of memory).
