Early Christmas Present from Google?

Check out the datastore stats after today's maintenance...

I really really really hope it stays this way ;] 

Latency dropped from 300 msec to 100msec for me

It looks like they performed some seriously powerful voodoo spells during the maintenance :)

Well done, Googlers, thank you!

Very impressive! Datastore is screaming right now!

Whoever engineered this fix deserves a raise!

Totally awesome, I'm going to have some happy users if this keeps up.

Does this mean we're out of beta? :-)

Great job Google! Thank you!!!

:)

[Steve]

I just noticed, in addition to the halved RPC latencies (datastore,
memcache, everything) it looks like instances on my low traffic site
are living longer too! I used to see new instances created if I got
no requests for 2-3 minutes. Right now they're living for 10-15
minutes! Fantastic!

I noticed another great improvement: much faster app uploads. See my
comments in this thread:

Amazing. I just pray that this is not temporary.

Thank you, and good job.

A site I like to look at that keeps independent stats can be found here:

http://amistrongeryet.com/op_detail.jsp?op=gae_db_readNonTransactional

Back when the Sept 13th maintenance happened, you could see the pronounced difference (for the worse)... now, you can see the pronounced difference for the better.

Ojala, this wild-n-out performance will stick.  See here for general cloud stats (my personal opinion has always been the Appengine allowed a wilder 99th percentile performance to give better median performance on gets and puts.. while, say, Amazon Simple DB gave slower read performance in exchange for a lower 99th percentile.  Whatever happens with the datastore performance from now on, I like the approach they're taking):

+1. Simple amazing, across all my apps.

Where do I send the case of beer? (Or would a box of k'nex be a better choice?)

[Jamie H]

Had to comment again on this mind blowing performance.

Right now gae status page showing datastore get() latency about 5ms
while memcache get() latency is about 3ms.

If you improve any more you are going to deprecate memcache!

Kudos Google.

Thank you app engine team! Way to grease the pistons

Impressive performance gains - congratulation to Google and App Engine
team.
Lets hope current performance will be a benchmark for the future.

Thanks googlers! This is awesome.

[Julian Namaro]

Back in July, and even after a maintenance before that I noticed a
significant lower latency in the few days right after the maintenance.
It never last though, so we should probably wait a few more days
before assessing the results. I wonder what kind of changes in
BigTable could cause a temporary improvement...

Really great job !!! well done !!

[john]

Me too -- my apps are noticeably faster. How these guys at Google do
it?

I am also seeing much better performance - including quicker startup
times for a new java instance.

Thanks,

Blazin'! Great work!

Hey everyone,

Thanks for the great feedback! Going forward, we're cautiously optimistic about the datastore improvements. You should continue to code using best practices - that is, don't assume datastore get() will always run in 5ms and place make 200 get calls serially. We'll be watching the performance closely in the meantime.

Are you able to share any details on what exactly happened behind the
scenes?

Hmm... unfortunately it seams that some of the issues have reappeared
(high 500 error rate, high latencies, etc). Is this happening to other
apps or just mine ?

[Uberto Barbini]

fantastic, now we have
>Request InvoiceListRequest successfully processed in 16 ms

it was about 100ms before...

thanks!

[Oboero Admin]

Ice,

I'm also experiencing an unacceptably high number of 500 errors.

FYI,

Patrick

[dloomer]

Me too, although it seems like it's been that way all week (noticeably
worse today, though).

[Raymond C.]

The situation hasn't been improved for me since Sept's maintenance.
Ya responds are faster, but those timeout still the same.
