I'm relatively sure it is just TF2 right now.
I'm sure it'll make its way to the other games once the fix is confirmed
to work, but whether it's brought sooner (in its current workaround-y form
/w these cvars) or later (once the issue itself is genuinely fixed) is
anybody's guess.

Was this prerelease just pushed for TF2 or all Steampipe converted Source
games? Will the new compression scheme (if switched) be rolled out to all?

I just updated mine, and both commands are showing up fine. Try doing a
validate on the server you updated to make sure it didn't miss anything
Also, I'm not sure how many other people are trying out this prerelease,
but if I find anything out from my regulars before others get some idea
whether this works/helps or not, I'll definitely contribute the info.

These are temporary measures to help diagnose and workaround the problem.
Once we confirm that this is the issue, we'll switch to Snappy or some
other fast compression library. Our own hand-rolled LZSS compressor is
known to be slow.

I forgot to ask you Fletcher.
Will sv_compressfragments and sv_**compressstringtablebaselines serve as
a permanent fix for this issue or is there more optimizations and a
different fix for this on the way? Are player spawns causing a spike (Which
I've always thought was normal, heh) something that is planned to be
fixed/optimized as well?
Thanks

No need to send any netspike files. We have enough good data and further
netspike files or vprof files are not likely to help right now. It anybody
wants to send in more windows traces, however, feel free to do so.
For some reason the servers are spending huge amounts of time in
compression code. The data from the traces and vprof is very consistent.
Specifically, compressing string tables and fragments can sometimes take a
very large amount of time. The LZSS compression code has not changed in
ages. The contents of the string tables, as far as I can tell, did not
change significantly in the SteamPipe update. I am still at a loss to
explain what changed in the SteamPipe update.
There are also occasionally mini-spikes when a player spawns, but I don't
think that's new.
I have a new "prerelease" beta that adds two convars that can be used to
totally disable compression:
sv_compressfragments - defaults ON (existing behavior to try to compress
all fragments by default)
sv_**compressstringtablebaselines - default OFF (new beahvior to turn
off compression by default)
You can switch these at any time, but sv_compressfragments is "sticky"
--- it takes effect on a per-client basis, at the time when a client
connects.
You might try turning both of those off and see how performance changes
or if any problems occur. Of course, this will increase bandwidth. But it
would help to confirm that this is indeed the problem.
If anybody wants to do their own data gathering to see where the time is
going, without the data gathering itself causing spikes that might not have
otherwise occurred, I'd recommend the following netspike / vprof settings:
vprof_on
vprof_dump_spikes 20
sv_netspike 0
sv_netspike_sendtime_ms 2
sv_netspike_output 2

Been catching the spikes with the new commands, should we email them to
someone?
