Intention was that each debug & each release variant has it's own signing key (4 variants -> 4 signing keys), no signing with default key. But this doesn't work
...
signingConfigs {
// debug config is intentionally deleted in favor of debugBlue & debugRed
debugBlue {
storeFile file(debugBlueKeystore)
}
debugRed {

All debug variants are signed with same (custom defined) debug.key , each release variant has it's own specific {flavor}_release_keystore. No default debug.key (autogenerated from system) is used
signingConfigs {
debug {
storeFile file("debug.keystore")
}
releaseBlue {
storeFile file('blue_release.keystore')
storePassword "blueblue"
keyAlias "alias_name"
keyPassword "blueblue"

Latency numbers every programmer should know

Latency numbers every programmer should know

L1 cache reference ......................... 0.5 ns
Branch mispredict ............................ 5 ns
L2 cache reference ........................... 7 ns
Mutex lock/unlock ........................... 25 ns
Main memory reference ...................... 100 ns             
Compress 1K bytes with Zippy ............. 3,000 ns  =   3 µs
Send 2K bytes over 1 Gbps network ....... 20,000 ns  =  20 µs
SSD random read ........................ 150,000 ns  = 150 µs

Read 1 MB sequentially from memory ..... 250,000 ns = 250 µs
