You'd be surprised. When a new player connects and uploads his spray, all
the clients currently connected will go to download it. Each time a client
downloads it, srcds lists the entire contents of the downloads directory as
a naïve way of checking that the file exists, then open the file, then
transfer the file. On a bogged down disk with a full server and a large
downloads directory where this will be occurring 30 times or so in quick
succession, it can cause noticeable lag.

However, I will concede that if you're reliably noticing issues exactly at
the start and end of the update process, that this is probably not the
issue. I have no idea what else it could be though.

Hi,

The server has 3 Cheetah 15k SAS drives in RAID configuration, I am quite
positive these aren't the issue, especially not because writing sprays and
logs are just a couple hundred KB's at the time.

Cheers,

The update tool causes a lot of disk activity. It's possible your servers
are attempting to access the disk and lagging on some of the synchronous
operations (flush the log file, upload/download a player spray). I've
noticed similar problems and have come to this conclusion. It hasn't really
bothered me since it has been minor and only during updates.

Subject: [hlds_linux] Lag issues on running updates

Hi,

As soon as we run an update on one of our game servers, the other game
servers are getting 2 short lag bursts (takes a few seconds each). This
happened on running the command "./steam -command update -game tf -dir
/bla/bla -verify_all". It's reproducible as it occurs every time you run an
update.

The issue is not caused by not having enough resources. We can put a lot of
extra load on the machine without affecting any of the game servers. It
looks like the update process somehow causes a small machine stall twice in
its process, once during the start, and one at the end.

Our servers run Debian Squeeze with the default supplied kernel.

Anyone else experiencing these issues?

Cheers,

Saint K.
