Hey Fletcher,
On my TF2 servers I did update all of them to the prerelease and used:
sv_compressfragments 0
sv_compressstringtablebaselines 0
And the SV spike issues went away, even up to 32 players its smooth as
butter again like it was pre-steampipe. While it uses more bandwidth,
its a small sacrifice to get gameplay smooth again.
Very happy and so are the players :)

We?ll confirm the fix in TF2. Then release with the other games soon after.

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

fletch...@valvesoftware.com<mailto:fletch...@valvesoftware.com><mailto:fletch...@valvesoftware.com<mailto:fletch...@valvesoftware.com>> I'm not sure if they're still wanting logs or not. I think they've kind of found where the problem is. I don't know what it would hurt
though.

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