I checked a few older versions and GS 2.16 shows much smaller numbers, about 5% CPU. Andrea Aime made a quick analysis and suggested that the OSHI library is responsible for the load. If I understood right something may go wrong with detecting the processor type. This is what the Windows systeminfo tells about that: System Type: x64-based PC Processor(s): 1 Processor(s) Installed. [01]: Intel64 Family 6 Model 142 Stepping 10 GenuineIntel ~1910 Mhz The jstack outputs from both GS 2.16 and GS 2.20 are attached.
