Hi, We do have a few high load web servers behind two load balancers running \* nginx/1.0.0\* I upgraded two of them to _nginx/1.0.12_ all servers are running well despite the version of nginx However I’ve noticed that there is a big difference in active connections between the old version and the new version. What do you think about it, is it bad or good. _nginx/1.0.12_ _Linux 2.6.18-194.17.1.el5 #1 SMP Wed Sep 29 12:50:31 EDT 2010 x86\_64 GNU/Linux_ _CentOS release 5.7 (Final)_ \*Active connections: 117 \* _server accepts handled requests_ - 12710947 12710947 12710947 \* \*Reading: 0 Writing: 117 Waiting: 0 \* - - _nginx/1.0.12_ _Linux 2.6.18-274.12.1.el5 #1 SMP Tue Nov 29 13:37:46 EST 2011 x86\_64 GNU/Linux_ _CentOS release 5.7 (Final)_ \*Active connections: 74 \* _server accepts handled requests_ - 31879742 31879742 31879741 \* \*Reading: 0 Writing: 74 Waiting: 0 \* _nginx/1.0.0_ Linux 2.6.18-238.9.1.el5 #1 SMP Tue Apr 12 18:10:13 EDT 2011 x86\_64 GNU/Linux CentOS release 5.6 (Final) Active connections: 1 server accepts handled requests 1745405552 1745405552 1745405549 Reading: 0 Writing: 1 Waiting: 0 _nginx/1.0.0_ Linux 2.6.18-238.9.1.el5 #1 SMP Tue Apr 12 18:10:13 EDT 2011 x86\_64 GNU/Linux CentOS release 5.6 (Final) Active connections: 1 server accepts handled requests 1777800935 1777800935 1777800935 Reading: 0 Writing: 1 Waiting: 0 _nginx/1.0.0_ Linux 2.6.18-238.9.1.el5 #1 SMP Tue Apr 12 18:10:13 EDT 2011 x86\_64 GNU/Linux CentOS release 5.6 (Final) Active connections: 6 server accepts handled requests 638878235 638878235 638878235 Reading: 0 Writing: 6 Waiting: 0 _nginx/1.0.0_ Linux 2.6.18-238.9.1.el5 #1 SMP Tue Apr 12 18:10:13 EDT 2011 x86\_64 GNU/Linux CentOS release 5.6 (Final) Active connections: 5 server accepts handled requests 1785279854 1785279854 1785279852 Reading: 0 Writing: 5 Waiting: 0 _nginx/1.0.0_ Linux 2.6.18-238.9.1.el5 #1 SMP Tue Apr 12 18:10:13 EDT 2011 x86\_64 GNU/Linux CentOS release 5.6 (Final) Active connections: 4 server accepts handled requests 1795180194 1795180194 1795180190 Reading: 0 Writing: 4 Waiting: 0 _nginx/1.0.0_ Linux 2.6.18-238.9.1.el5 #1 SMP Tue Apr 12 18:10:13 EDT 2011 x86\_64 GNU/Linux CentOS release 5.6 (Final) Active connections: 4 server accepts handled requests 1792770090 1792770090 1792770085 Reading: 0 Writing: 4 Waiting: 0 _nginx/1.0.0_ Linux 2.6.18-274.12.1.el5 #1 SMP Tue Nov 29 13:37:46 EST 2011 x86\_64 GNU/Linux CentOS release 5.7 (Final) Active connections: 6 server accepts handled requests 1374777486 1374777486 1374777465 Reading: 0 Writing: 6 Waiting: 0 ## Best Regards \* - _Iqbal A._ _+212 665 025 032_ _removed\_email\_address@domain.invalid_ ---
