LeWiz Communications and Synchromesh Computing Announce
Best TCP/IP Offload Engine Benchmark Results

Certified benchmark scores prove best in breed bi-directional Performance Efficiency Index.

San Jose, CA and Austin, TX (May 9, 2005)- LeWiz Communications, a fabless semiconductor company, and Synchromesh Computing, a leading benchmark and certification company, announced that the LeWiz TCP/IP Offload Engine (TOE) HBA received the highest Performance Efficiency Index (P.E.I.) measured using standard benchmarks under high TCP/IP load or varying data sizes.

Compared against existing product offerings from Intel, Alacritech, Adaptec, and Broadcom, the LeWiz MAGIC2020™ multi-port HBA consistently offloaded more of the host CPU and outperformed all other TCP/IP offload NICs or standard NICs studied across a wide range of tests.

When data sizes were varied from small (4KByte) to large (512KByte) sizes, the LeWiz’s solution offers 2 to 3 times better in overall system performance efficiency. When TCP/IP loads were varied from low (1) to higher normal (512 bi-directional) loads, the LeWiz solution offers about 3 times better in system performance efficiency than any other solution. Some competing products on the market cannot function reliably at the higher TCP/IP load. The LeWiz’s Magic2020™ HBA consistently performs reliably even under the most stressful conditions.

“Over 5 years of development and tuning really pay off for LeWiz. Today, LeWiz’s hardware-based architecture proves that it is the best solution on the market from performance to reliability. Yet, we can do it at a fraction of the power consumption of any other solution. Simply amazing!” said Chinh Le, LeWiz’s CEO.

“At first, Synchromesh Computing was a bit skeptical about the very concept of using a separate processor to reduce the workload of the main CPU or CPU’s in a PC or server machine”, said Synchromesh Computing CEO Alan R. Weiss. “We found that indeed this works as designed. First, we proved the very value proposition of TCP/IP Offload Engines in general, and then we found that the LeWiz solution (LeWiz MAGIC 2020 TCP/IP Offload Engine) is superior to the Alacritech and Adaptec offload engines, and also superior to the Intel Gigabit Network Interface Card (NIC) and the Broadcom 10Base1000 NIC for the tests we performed. We have the certified data to back up these statements”, he explained. “This young company really has the goods.”
