without bandwidth throttling, a server could efficiently serve only 100 active TCP connections (100 MB/s / 1 MB/s) before saturating network bandwidth; a saturated network (i.e. with a bottleneck through an Internet Access Point) could slow down a lot the attempts to establish other new connections or even to force them to fail because of ...
An additional minimum interframe gap corresponding to 12 bytes is inserted after each frame. This corresponds to a maximum channel utilization of 1526 / (1526 + 12) × 100% = 99.22%, or a maximum channel use of 99.22 Mbit/s inclusive of Ethernet datalink layer protocol overhead in a 100 Mbit/s Ethernet connection.
Early scholarly studies in 2004 indicated that TCP traffic in particular exhibits a bimodal distribution with spikes around minimum-sized packets (less than 100 bytes) and Ethernet MTU (more than 1400 bytes). [1] Later studies confirmed this for backbone [2] [3] and enterprise [4] networks.
Percent bandwidth is a less meaningful measure in wideband applications. A percent bandwidth of 100% corresponds to a ratio bandwidth of 3:1. All higher ratios up to infinity are compressed into the range 100–200%. Ratio bandwidth is often expressed in octaves (i.e., as a frequency level) for wideband applications.

[citation needed] Enterprise class SATA HDDs, such as the Western Digital Raptor and Seagate Barracuda NL will improve by nearly 100% with deep queues. [4] High-end SCSI drives more commonly found in servers, generally show much greater improvement, with the Seagate Savvio exceeding 400 IOPS—more than doubling its performance.
Jumbo frames have payloads greater than 1500 bytes. In computer networking, jumbo frames are Ethernet frames with more than 1500 bytes of payload, the limit set by the IEEE 802.3 standard. [1] The payload limit for jumbo frames is variable: while 9000 bytes is the most commonly used limit, smaller and larger limits exist.
KASY0 was the first sub-US$ 100/GFLOPS computing technology. KASY0 achieved 471 GFLOPS on 32-bit HPL. At a cost of less than $39,500, that makes it the first supercomputer to break $100/GFLOPS. [81] August 2007: $48.31 $70.99 Microwulf As of August 2007, this 26 GFLOPS "personal" Beowulf cluster can be built for $1256. [82] March 2011: $1.80 $2 ...
