Performance Testing Between Matisse Sites

• Performance testing conducted between sites using
  the following systems/configurations
• 1500 byte MTUs
• mix of 400Mhz1Ghz processesor intel machines
  with Linux
• mix of 64 bit/66 Mhz and 32bit/33 Mhz PCI bus
  machines
• SysKonnect, Intel, 3Com, or Alteon Gigabit
  Ethernet NIC cards
• Single Stream UDP, Single Stream TCP, Multiple
  Stream TCP
• iperf application (http//dast.nlanr.net/Projects/
  Iperf/)
• SuperNet Monitoring Testing tools
• www.ngi-supernet.org/arch-engr.html

Summary/Issues/Future Upgrades

• Expectations for SuperNet connected hosts with
  1500 byte MTU, when using a machine with Dual
  Ghz processors, and 64bit/66Mhz pci bus
• 300-400 Mbits/s UDP, 150-250 Mbits/s single
  stream TCP
• Expectations met for some host/network locations
  and not others
• Performance for sites not directly connected to
  SuperNet (LBL,UCB) is less than
  desired/acceptable due to
• Other network infrastructure link speeds
• Other network infrastructure equipment
  types/configurations
• asymmetric routes
• Future upgrade recommendations/plans
• Analyze and determine what the host variation
  factors are(cpu, nic card type, pci bus, os)
• Analyze and debug network issues (PSC/CMU local
  infrastructure?wan connection?)
• reconnect other sites (LBL and UCB) to SuperNet
• change MTU sizes to 4470 bytes (to match SONET)
• requires some equipment purchases
• ensure all hosts are GHz processor with
  64bit/66Mhz PCI bus
• upgrade BossNet to OC48
• Expectations are that we will be able to achieve
  about 600 Mbits/s single stream TCP between all
  Matisse sites with these upgrades.
