Many servers download repo together, repo sync stuck

[Matthew Song]

Could you elaborate on stuck? Are there many connections
building up in your gerrit queue, and they are only being
processed slowly? It sounds like you need more hardware.

What is your ssh thread count set to? How many cores do you
have? The cores and thread count limit the amount of
concurrent work being done. What "-j" are the repo syncs
using?

Likely you need some slaves (Gerrit mirrors) to offload the
work,

Hi, thanks for your reply.

1. stuck happen any stage of repo sync , then stuck for hours.

2. threads = 96, 12 core , default use -j4

Hi,

It is still unclear what you mean with 'stuck', but the only case where I have seen repo with -j option goes 'stuck' is with Python version 2.7.2. It has a threading bug and a newer version is mandatory. But this is a long shot for this case given the lack on detals :-)

Kind regards,

Remy
