AppFlex Software

Now you can selectively deploy network services to accelerate, monitor and secure applications within your network.


Onload application acceleration middleware significantly enhances application performance by improving network I/O latency, bandwidth, and message rates, while reducing CPU utilization all with no need to modify applications or change the network infrastructure. Solarflare also offers EnterpriseOnload®, which bundles support and service level agreements with an Open Source software subscription.

Onload Application Accelerator

Solarflare's Onload is a Linux-based, high-performance application accelerator that delivers lower and more predictable latency and higher message rates for TCP and UDP-based networked applications. Onload is ideal for applications that benefit from lower latency (with decreasing jitter) and higher throughput, including financial services, geosciences, biosciences, weather and other HPC applications. A key recent addition to Onload is the TCPDirect library focused on offering applications the lowest possible latency between the application and the network. TCPDirect has its own zero-copy user-space API offering conceptually similar semantics to a subset of the BSD sockets API and so can co-exist with Onload within the same application. Its role is where latency is paramount and a broad TCP/IP feature-set is not required.

NOTE: TCPDirect is only available on the SFN8000-series Onload and Plus adapters.

  • TCP and UDP acceleration including multicast
  • Lowest application-to-application latency in a fully featured RFC-compliant stack
  • Up to 3 million messages per second on a single CPU core
  • Binary compatible BSD sockets API
  • No application modifications or network upgrades required
  • The absolute minimum of latency for applications requiring this feature via the TCPDirect library
