nginx enable compression and JS/CSS files

So one of my old colleague was trying to find some quick way of increasing performance for his pet project website so he asked me to take a look.  First thing I did was ran pagespeed and immediately I saw compression was off, css/js was not aggregated. JS/CSS aggregation would require either build changes or installing pagespeed so I thought quick 1 hour fix would be to just enable compression so I went and enabled " gzip  on;"  in nginx conf and it gave a good bump on login page but the home page after login, it kept complaining about JS/CSS not being compressed. I was scratching my head and left it as is that day.

Yesterday night finally I found out that turning gzip on would only compress text/html by default in nginx.  You need to explicity turn it on for other types. So I went and added the below and problem was solved.

    gzip_types  text/plain application/xml text/css text/js text/xml application/x-javascript text/javascript application/javascript application/json;
  

While doing this I also installed pagespeed with nginx. It was not as fun as installing it in apache because for nginx if you have to add module you need to recompile it from source. But it was worth it.  The pagespeed score that was 60 went up to 90.

I really like products that removes human touchpoints, Pagespeed is one of them, Thanks to Google for creating this awesome product.  At my employer's website before pagespeed I had to hunt developers every release to see if they had added proper version tags, they had followed build time aggregation guidelines and due to our release velocity, this was the first thing that was sacrificed and debt would keep piling up release after release. One day some customer would complain and everyone would scramble to get it fixed in one week. But thanks to pagespeed no more of this shit.

What a rocky start to labor day weekend

Woke up by earthquake at 7:00 AM in morning and then couldn't get to sleep. I took a bath, made my tea and started checking emails and saw that after last night deployment three storage node out of 100s of nodes were running into Full GC. What was special about the 3 nodes was that each one was in a different Data centre but it was named same app02.  This got me curious I asked the node to be taken out of rotation and take a heap dump.  Yesterday night a new release has happened and I had upgraded spymemcached library version as new relic now natively supports instrumentation on it so it was a suspect. And the hunch was a bullseye, the heap dump clearly showed it taking 1.3G and full GCs were taking 6 sec but not claiming anything.



I have a quartz job in each jvm that takes a thread dump every 5 minutes and saves last 300 of them, checking few of them quickly showed a common thread among all 3 data centres. It seems there was a long running job that was trying to replicate pending…

Email slavery

It seems I have become an EmailSlave. The first half of the day is spent in just answering to emails. There are so many emails where I am copied but I need not be. There are many emails  where its a 1-2 page email and somewhere down someone says @KP please answer this.  So it seems daily my work schedule is:
Signin to newrelic and check anomalies for 15 min. Check emails related production exception report and yes there are a ton of these report daily. Need a better tool here as this model is not scalable. I need to reduce the incoming data at me to only see relevant data like what newrelic does. May be I need to create a webapp out of these emails.Check emails for next few minutes before team callsDo team callsThen again back to checking emails until a I have taken a best shot at answering everyone waiting for my reply.Attend team meetings on Tue/Thu
Being an architect and coder at heart I don't feel satisfied at end of the day if there is nothing tangible getting done at the end.…
