It is possible - but it would be difficult to optimize for every performance characteristic because they are derived from many different benchmarks. This was a problem in the tpc-c years with database vendors optimizing specifically for a s

The intent of the fio testing was to measure block storage not cache I/O. direct I/O was set in fio configs, but is usually not honored by the hypervisor. During run-up a 100% fill test was performed using refill_buffers and scram

GCE no longer offers a local storage option, this is one reason slower IO. They also cap IOPS for better IO consistency.

A t2.medium starts with enough credits for about 15 minutes of 2 core CPU saturation and accumulates 12 minutes/hour thereafter. In non-burst mode it is about 5X slower. For this type of workload you'd likely be better off with a

Tests are from your connection using whatever resolver chain your ISP has in place. It uses a wildcard name record and an 8 byte json-p include. It alternates between downloading that file from the same origin using a cached DNS record (tes

It's a start - barebones authoritative DNS only - no monitoring/failover, load balancing, Geo, LBR, etc - provisioning via API only. Route 53 started out this way, and has since added many of these features and now has almost 7% A

The EC2 C3 instance type is going to be about the same price as DO for 1 year reserve and less than DO for 3 year. Spot pricing will also be lower than DO for C3s. On top of that EC2 is far superior to DO in many ways: EBS off instance sto

I've had this happen while flying military helicopters at night. We usually get a grid or address, and report it when we land.

This is nothing new. Conforming loans for self employed have always required 2 years tax returns. I just went through this process myself. It is more painful than W2, but if you have 2 years returns, acceptable debt to income ratio, and dec

I lived in Utah which can get very smoggy due to winter inversions. PM2.5 levels sometimes hit 80 mcg in the winter, often the highest in the country and utterly depressing to live in.

You're better off evaluating CDNs using real user/last mile testing than a few pingdom servers in data centers. Cedexis has has some decent analysis of this type on their website: http://www.cedexis.com/country-rep

Aircrews have their own ROE and approval process for engagements. They aren't simply trigger pullers for the JTAC. However, there is an implicit trust in the JTAC, and desire to protect the ground unit. If ROE is satisfied and approval

Keep in mind that the JTAC is usually an enlisted soldier embedded with a ground unit. He is highly trained on ROE and positive ID, and generally has a good first hand perspective on what is happening on the ground. He is responsible for pr
