This page will be constantly evolving as new measurements are made and new benchmarks are added.Under each clickable benchmark item you should find an explanation ofthe test, the source code for the benchmark for each system (<i>still not ready, sorry <b>-Stefan</b></i>), and possibly some discussion about the significance ofthe results. Some pages have not yet been completed, please bear with us.<p><b>Note</b>: This page uses the table extension and may not be viewable with all viewers.<hr><h2><li>Control Transfer</h2><ul><h3><li><a href=ControlTransfer/index.html#ProtectedCall>Protected in-kernel call</a></h3><TABLE BORDER> <TR> <TH>DEC OSF/1</TH> <TH>Mach 3.0</TH><TH>SPIN extension</TH> </TR> <TR> <TD ALIGN=RIGHT>n/a</TD> <TD ALIGN=RIGHT>n/a</TD> <TD ALIGN=RIGHT>.13 usecs</TD> </TR></TABLE> </ul><ul><h3><li><a href=ControlTransfer/index.html#SystemCall>System call</a></h3><TABLE BORDER> <TR> <TH>DEC OSF/1</TH> <TH>Mach 3.0</TH><TH>SPIN extension</TH> </TR> <TR> <TD ALIGN=RIGHT>5 usecs</TD> <TD ALIGN=RIGHT>7 usecs</TD> <TD ALIGN=RIGHT>4 usecs</TD> </TR></TABLE> </ul><ul><h3><li><a href=ControlTransfer/index.html#IPC>Cross-address space call (IPC)</a></h3><TABLE BORDER> <TR> <TH>DEC OSF/1</TH><TH>Mach 3.0</TH><TH>SPIN extension</TH> </TR> <TR> <TD ALIGN=RIGHT>845 usecs</TD> <TD ALIGN=RIGHT>104 usecs</TD> <TD ALIGN=RIGHT>89 usecs</TD> </TR> <TR> <TD ALIGN=RIGHT>124 usecs</TD> <TD ALIGN=RIGHT>873 usecs</TD> <TD ALIGN=RIGHT>117 usecs</TD> </TR></TABLE> </ul><h2><li>Thread Management</h2><ul><h3><li><a href=ThreadManagement/index.html#KernelThreads>Kernel Thread Interface</a></h3><TABLE BORDER> <TR> <TH></TH><TH>DEC OSF/1</TH><TH>Mach 3.0</TH><TH>SPIN extension</TH> </TR> <TR> <TH ALIGN=RIGHT>Fork-Join</TH><TD ALIGN=RIGHT>198 usecs</TD><TD ALIGN=RIGHT>101 usecs</TD><TD ALIGN=RIGHT>22 usecs</TD> </TR> <TR> <TH ALIGN=RIGHT>Ping-Pong</TH><TD ALIGN=RIGHT>21 usecs</TD><TD ALIGN=RIGHT>71 usecs</TD><TD ALIGN=RIGHT>17 usecs</TD> </TR></TABLE> </ul><ul><h3><li><a href=ThreadManagement/index.html#UserThreads>User Thread Interface</a></h3><TABLE BORDER> <TR> <TH></TH><TH>DEC OSF/1</TH><TH>Mach 3.0</TH><TH>SPIN layered</TH><TH>SPIN integrated</TH> </TR> <TR> <TH ALIGN=RIGHT>ForkJoin</TH><TD ALIGN=RIGHT>1230 usecs</TD><TD ALIGN=RIGHT>338 usecs</TD><TD ALIGN=RIGHT>262 usecs</TD><TD ALIGN=RIGHT>111 usecs</TD> </TR> <TR> <TH ALIGN=RIGHT>Ping-Pong</TH><TD ALIGN=RIGHT>264 usecs</TD><TD ALIGN=RIGHT>115 usecs</TD><TD ALIGN=RIGHT>159 usecs</TD><TD ALIGN=RIGHT>85 usecs</TD> </TR></TABLE> </ul><h2><li>Memory Management</h2><ul><h3><li><a href=MemoryManagement/index.html#MemoryProtection/>Memory protection</a></h3><TABLE BORDER> <TR> <TH></TH><TH>DEC OSF/1</TH><TH>Mach 3.0</TH><TH>SPIN extension</TH> </TR> <TR> <TH ALIGN=RIGHT>Dirty</TH><TD ALIGN=RIGHT>n/a</TD><TD ALIGN=RIGHT>n/a</TD><TD ALIGN=RIGHT>2 usecs</TD> </TR> <TR> <TH ALIGN=RIGHT>Fault</TH><TD ALIGN=RIGHT>329 usecs</TD><TD ALIGN=RIGHT>415 usecs</TD><TD ALIGN=RIGHT>29 usecs</TD> </TR> <TR> <TH ALIGN=RIGHT>Trap</TH><TD ALIGN=RIGHT>200 usecs</TD><TD ALIGN=RIGHT>185 usecs</TD><TD ALIGN=RIGHT>7 usecs</TD> </TR> <TR> <TH ALIGN=RIGHT>Prot1</TH><TD ALIGN=RIGHT>45 usecs</TD><TD ALIGN=RIGHT>106 usecs</TD><TD ALIGN=RIGHT>16 usecs</TD> </TR> <TR> <TH ALIGN=RIGHT>Prot100</TH><TD ALIGN=RIGHT>1041 usecs</TD><TD ALIGN=RIGHT>1792 usecs</TD><TD ALIGN=RIGHT>213 usecs</TD> </TR> <TR> <TH ALIGN=RIGHT>Unprot100</TH><TD ALIGN=RIGHT>1016 usecs</TD><TD ALIGN=RIGHT>302 usecs</TD><TD ALIGN=RIGHT>214 usecs</TD> </TR> <TR> <TH ALIGN=RIGHT>Appel1</TH><TD ALIGN=RIGHT>382 usecs</TD><TD ALIGN=RIGHT>819 usecs</TD><TD ALIGN=RIGHT>39 usecs</TD> </TR> <TR> <TH ALIGN=RIGHT>Appel2</TH><TD ALIGN=RIGHT>351 usecs</TD><TD ALIGN=RIGHT>608 usecs</TD><TD ALIGN=RIGHT>29 usecs</TD> </TR></TABLE> </ul><h2><li>Networking</h2><ul><h3><li><a href=Networking/index.html#Latency>Latency</a></h3><TABLE BORDER> <TR> <TH>Network</TH><TH>DEC OSF/1</TH><TH>SPIN extension</TH> </TR> <TR> <TH ALIGN=RIGHT>Ethernet</TH><TD ALIGN=RIGHT>789 usecs</TD><TD ALIGN=RIGHT>565 usecs</TD> </TR> <TR> <TH ALIGN=RIGHT>ATM</TH><TD ALIGN=RIGHT>631 usecs</TD><TD ALIGN=RIGHT>421 usecs</TD> </TR></TABLE> </ul><ul><h3><li><a href=Networking/index.html#Bandwidth>Bandwidth</a></h3><TABLE BORDER> <TR> <TH>Network</TH><TH>DEC OSF/1</TH><TH>SPIN extension</TH> </TR> <TR> <TH ALIGN=RIGHT>Ethernet</TH><TD ALIGN=RIGHT>8.9 Mb/s</TD><TD ALIGN=RIGHT>8.9 Mb/s</TD> </TR> <TR> <TH ALIGN=RIGHT>ATM</TH><TD ALIGN=RIGHT>27.9 Mb/s</TD><TD ALIGN=RIGHT>33.0 Mb/s</TD> </TR></TABLE> </ul><hr>This page maintained by Stefan Savage.<address><a href="mailto:savage@cs.washington.edu">savage@cs.washington.edu</a></address></body></html>⌨️ 快捷键说明
