Hello everyone! I'm Krishanu. I'm a 3rd year CSE student would like to contribute to BookBrainz. I am a newbie to open source development. Can somebody point me to the right direction and get me started? Thanks!

zas: do we know stats from the old servers? i.e. the avg response time and the hits/s per server
oh, neat, I like that there's a base "entity" class.

bitmap: not really, we didn't have those we have now
2016-12-15 35016, 2016
bitmap
okay
2016-12-15 35032, 2016
bitmap
but we're handling less overall requests than before?

yes, we went up to 700 r/s on webservice at OldHost, we are currently at 350r/s on ws (rate limited), i could increase the rate limit, but the load is growing very fast
2016-12-15 35023, 2016
zas
but many things changed, comparing those values may not be a good idea. But the question is the following: how to reduce cpu usage on web servers ?
2016-12-15 35016, 2016
zas
ws response time is around 40ms at best, we could start to see if we can lower that.

right, it just seems surprising that the new servers are slower
2016-12-15 35010, 2016
zas
servers (hardware) is faster, but perhaps dockerized mbs is slower
2016-12-15 35052, 2016
bitmap
that's also surprising :)

ruaok want to us to monitor few urls, i would propose to use one xml request and one json

http + https

by the way, is the grafana still publicly available? if so, what is the user/pw combo?
2016-12-15 35048, 2016
bitmap
the code didn't change much, and we bumped perl from 5.18 to 5.22
2016-12-15 35014, 2016
zas
Leo_Verto: just sign in, and you're done
2016-12-15 35015, 2016
bitmap
so overhead from docker itself?
2016-12-15 35035, 2016
zas
bitmap: i dunno exactly, it shouldn't be that much
2016-12-15 35055, 2016
zas
ws doesn't use TT at all ?
2016-12-15 35001, 2016
bitmap
no, it doesn't

UmkaDK is jumping into the middle of a conversation and possibly getting the wrong end of a stick

bumped perl from 5.18 to 5.22?? Is that on MusicBrainz Slave Server?
2016-12-15 35030, 2016
Leo_Verto
zas, ah thanks, that didn't even occur to me :P
2016-12-15 35047, 2016
bitmap
UmkaDK: we're running 5.22 in production currently
2016-12-15 35055, 2016
zas
bitmap: we need to profile the code. At least to know in which direction we should go
2016-12-15 35006, 2016
UmkaDK
kk, thanks bitmap
2016-12-15 35013, 2016
bitmap
we still support 5.18 though
2016-12-15 35025, 2016
UmkaDK relaxes ... a lot!!

For a second I though I might have missed something very important! :)

zas: I'm still curious...if we set up a copy of the old codebase somewhere (using perl 5.18, memcached, no docker) and load-tested it on the same hardware
A friend of mine was in BCN last week. I should've had him hurry OTHER-261 for me. oops

UmkaDK, btw, I really appreciate how you're keeping close tabs on this channel. :) I wish more of our supporters' techies/staff would be as much around.

zas: can I move the mbs containers on hip to another node while I do profiling & other tests? not sure where to move them
2016-12-15 35052, 2016
bitmap
I have an mbs instance running perl 5.18.2 plus memcached minus docker on hip, too
2016-12-15 35023, 2016
bitmap
using the same code as production, just with the memcached changes reverted
2016-12-15 35053, 2016
bitmap
we could also just try pointing the gateway to this code, temporarily...it'll be using a different cache, but that possibly won't harm anything because it won't be serving edit pages
2016-12-15 35006, 2016
bitmap
it would serve stale web service responses in some cases, of course
