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

WARNING These steps are probably out dated and will not work.

To re-sign an iOS app with another developer account, ensure that the following are in place first.

1. Distribution certificate of the other developer account
2. A provisioning profile from the other developer account

Note that the Apple requires bundle IDs to be globally unique, even across accounts. So a bundle ID i.e. CFBundleIdentifier from one account can't be used in a different account, even though the team id/prefix would be different.

Ensure that the new distribution certificate is in your keychain and the new provisioning profile on your disk.
