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

IMPORTANT! Remember to check out the wiki page at https://github.com/bebraw/jswiki/wiki/Game-Engines for the most up to date version. There's also a "notes" column in the table but it simply does not fit there... Check out the raw version to see it.

This table contains primarily HTML5 based game engines and frameworks. You might also want to check out the [[Feature Matrix|Game-Engine-Feature-Matrix]], [[Game Resources]] and [[Scene Graphs]].

Attention: if you attempt to fork this gist, github will think that you are a spammer and you will have to confirm that you are human with them. Apparantly there are too many links in this list. Also I update it rather frequently (see revisions on the left), so it's probably wise to not fork it anyway.
