Comparative Measurements - SunOS

• less than or equal to 1K, Myrinet results in 1/3 the throughput of ATM and 100BASET using both netperf and blast.
• 100BASET produces highest throughput. Packet sizes 100-1500 bytes
• between 1-2K ATM outperforms Myrinet and 100BASET. Supporting graphs
• greater than 2K Myrinet provides highest throughput. See Supporting graphs
• Myrinet performance improves with optimized blast. Optimized blast graphs

• up to and just over 1K ATM achieves higher throughput than Myrinet.
• again, greater than 2K Myrinet outperforms ATM.
• At 4K Myrinet's throughput is nearly twice that of ATM.
• What happened to 100BASET? Graph

• Myrinet, ATM, 100BASET produce similar results using netperf and blast.
• 1K and above Myrinet and ATM show a 10% increase in throughput using optimized blast. Single Stream TCP Graphs

• Myrinet, ATM, 100BASET again produce similar results using netperf.
• Between 512-4096 Myrinet and ATM produce 5-10% higher throughput than 100BASET. Graph/s for Two TCP Streams
