Throughput and latency performance data

Tables 7 through 9 describe the performance capabilities of the 10-Gbps, 1-Gbps, and 100-Mbps interface
module ports of the ProCurve 6600 Switch Series . Over a range of packet sizes from 64 bytes to 1518 bytes,
the performance levels achieved are described in terms of the following metrics:
• Throughput-level percentage achieved when performing Layer 2 switching and Layer 3 routing; 100% in all
cases .
• Throughput in the form of the number of packets per second when performing Layer 2 switching and Layer 3
routing .
• Average per-packet latency in microseconds when performing Layer 2 switching and Layer 3 routing . These
values shown are listed for both First-In-First-Out (FIFO) and Last-In-First-Out (LIFO) processing . The LIFO values
represent the packet transmit time, whereas the FIFO values include the switch decision time and the packet
transmit time .
• Percentage of packets dropped in a full mesh configuration; 0% in all cases .
The following measurements were performed by ProCurve using test equipment manufactured by Ixia
Communications (www .ixiacom .com) . In these tests, the maximum number of supported ports on the ProCurve
6600 switch was used . Proportional performance results at 100% of throughput are achieved on the ProCurve
6600 Switch Series for the maximum number of ports supported by each model . The 1-Gbps table is not
applicable to the 6600-24XG switch because only 10-Gb ports are supported .

10-Gb performance traffic patterns

In Table 7, the performance levels for 10-Gb ports assume the underlying traffic patterns reflect either one of
the following minimum conditions to achieve wire-speed throughput:
• A single source traffic stream with an average packet size of 88 bytes or larger
• Two or more source traffic streams of any packet size down to the minimum value of 64 bytes
