Hi , I have tried out of curiosity other optimizations, such as using ByteArray to generate the string.
I have two variants: V3: generates the random hex bytes one by one, and writes them to the BA V4: generates 4 or 8 random bytes in one shot, and writes them to the BA (hexa in lowercase, to avoid call toUppercase() ) The results are the following : (200,000x , debug = true) Original: 4.48s JMcLean: 3.905s V3: 2.972s V4 : 2.404s Remark: V4 is the fastest, but it generates an UID with lower case abcdef instead of ABCDEF. I don't know if this is acceptable (are we breaking some code if we use lowercase instead of uppercase). If you want, I can post the code for the two variants...
