Performance tips

Here are some tips which can help to improve performance of ZenMake in some cases.

Hash algorithm

By default ZenMake uses sha1 algorithm to control changes of config/built files and for some other things. Modern CPUs often has support for this algorithm and sha1 shows better or almost the same performance as md5 in this cases. But in some other cases md5 can be faster and you can switch to use this hash algorithm. However, don’t expect big difference in performance of ZenMake.

It’s recommended to check if it really has positive effect before using of md5. To change hash algorithm you can use parameter hash-algo in buildconf features.
