Hi lava：

Some question about lava V2 2018.11+stretch：

1、 As lava running for weeks，it tasks minutes for the master to schedule jobs to the lava-slave ，and the normal time maybe 20s below.

When we restar both lava master and lava slave，it schedule job in 20s again. 

Can you tell us how to solve the problem，thanks very mutch.

2、we want to know how lava code works，can you give us some document. Sometimes we want to modify the lava steps，but we don’t know how to do.
