Each 1 MB chunk is then sent through the network. At this point SMB is the communication protocol. SMB divides each 1 MB chunks in smaller chunks (up to 64 KB each) and is requesting the network adapter to send them to the destination.<br \/>\n<em>Let&#8217;s pause a bit the explanation and mention <a href=\"https:\/\/en.wikipedia.org\/wiki\/Large_segment_offload\" target=\"_blank\">Large Segment Offload (LSO)<\/a> &#8211; which &#8220;is a technique for increasing outbound throughput of high-bandwidth network connections by reducing CPU overhead. It works by queuing up large buffers and letting the network interface card (NIC) split them into separate packets.&#8221;<\/em><br \/>\nContinuing the file share explanation: actually those SMB smaller chunks (up to 64 KB each) are sent over the network in much smaller size packets. The size of those packets is in direct relation with the <a href=\"https:\/\/en.wikipedia.org\/wiki\/Maximum_transmission_unit\" target=\"_blank\">Maximum Transmission Unit<\/a> size.<br \/>\n<em>Let&#8217;s pause again the explanation and mention in the absence of <a href=\"https:\/\/en.wikipedia.org\/wiki\/Large_segment_offload\" target=\"_blank\">Large Segment Offload (LSO)<\/a> (TSO \/ TCP Chimney Offload) the 1 MB chunks will be directly divided to packets in size with the Maximum Transmission Unit.<\/em><\/p>\n<p>On the other &#8220;end of the wire&#8221;, the system where the file is written to, will receive network packets who will not exceed the Maximum Transmission Unit size.<br \/>\n<span style=\"text-decoration: underline;\">The purpose of this explanation is to help reproduce as close as possible the file share network traffic using IOmeter.<\/span><\/p>\n<p>&nbsp;<\/p>\n<p><em>Of course, the way the data is handled (processed) before being passed to the network interface card has its performance implications &#8211; but this is a different subject.
