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.

See the explanation about 10-Gb performance traffic patterns in the next section.
Table 7: 6600 series throughput performance
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
