Thinking in Mobile Apps and Mobile Sites Performance

Yes, I have to say it: I’m a Performance junkie; I’m trying always to the fastest and suitable solution for a particular problem in the architecture of the platforms where I’m involved. In my case, I learned a lot about caching systems, HTTP servers optimization (my favorite is Nginx right now), Databases systems tuning, and more. But everything changed when I was charged to lead the first Mobile…

Listar todas las conexiones TCP a puerto 80

netstat -tunva|grep 80

Y enumerarlas:

netstat -tunva|grep 80|wc -l

Conexiones máximas que acepta nuestro sistema:

ulimit -n

Connections grouped by stat

netstat -an|awk '/tcp/ {print $6}'|sort|uniq -c

Connections in TIME_WAITED

netstat -n | grep TIME_WAIT | wc -l

How long connections will last?

netstat -on | grep TIME_WAIT | less

keep in mind!

tcp_tw_recycle - BOOLEAN Enable fast recycling TIME-WAIT sockets. Default value is 0. It should not be changed without advice/request of technical experts. tcp_tw_reuse - BOOLEAN Allow to reuse TIME-WAIT sockets for new connections when it is safe from protocol viewpoint. Default value is 0. It should not be changed without advice/request of technical experts.
