When there is no IO being done by the VM then there is no return IO for the host and ack gets sent after a time out. single-channel platform performance for Adobe Premiere, gaming, video encoding, transcoding, number crunching, and daily use. RAM (Random Access Memory) is the memory that your computer uses to store data from programs that are in use. It takes more time to fetch data from RAM than it takes to retrieve it. It is derived from dividing the column access time by the clock frequency, and raising the result to the next whole number. For these charts the 0-7 on the horizontal and vertical headers correspond to NUMA nodes. Here is the same system with DDR4-2666 DRAM:. Measuring latency is typically done using one of the following methods: Round trip time (RTT) - Calculated using a ping, a command-line tool that bounces a user request off of a server and calculates how long it takes to return to the user device. Because the CAS latency is specified in clock cycles, and not transfer ticks (which occur on both the positive and negative edge of the clock), it is important to ensure it is the clock rate that is being used to compute CAS latency times, and not the doubled transfer rate. NAND flash SSDs have revolutionized the storage world in the last 10 years. For the transaction log, you really want the average write latency to be in the 0-5ms range, and it's good to see more than 79% of transaction log files in the survey are achieving that. The interesting part is that memory bandwidth is a factor of latency. You want the timing to depend on the memory controller's latency, without any extra processing delay, so the SP (even just one thread) should be doing nothing but waiting for that memory read to finish. The problem is that the latency is measured in tens of nanoseconds, and when a modern CPU can execute 12 to 24 instructions per nanosecond. But as your business picks up, your datasets get larger, and your customers grow more demanding, replication can start to fall. Memory bandwidth is the rate at which data can be read from or stored into a semiconductor memory by a processor. This is why 1600mhz DDR3 memory appears as 800MHz in cpuid. For our purposes, it is the amount of time it takes a packet to travel from source to destination. Switch off the computer from time to time as opposed to just putting it to sleep (which maybe the default in your PC's power plan). It's a great developer tool that lets you scale out data to multiple servers, even using Standard Edition.
