Hi, I am Rajeev,
I am using Kannel from past 2 years. I am having 2 servers of kannel with following specs: Kannel bearerbox version `svn-r5106'. Build `Sep 30 2014 01:09:31', compiler `4.4.7 20120313 (Red Hat 4.4.7-4)'. System Linux, release 2.6.32-431.20.3.el6.x86_64, version #1 SMP Thu Jun 19 21:14:45 UTC 2014, machine x86_64. Hostname xxxxxx.xxxxx, IP xxx.xxx.xxx.xxx. Libxml version 2.7.6. Using OpenSSL 1.0.1e-fips 11 Feb 2013. Compiled with MySQL 5.5.38, using MySQL 5.5.38. Using native malloc. 1. at Digital Ocean VPS(SINGLE CORE 512 MB RAM 20GB HDD) 2. My Office Premises (hp proliant Intel® Xeon® E3-1220 v2 (4 core, 3.4 GHz, 8MB), 1TB & 4 GB RAM. My Problem: VPS is giving me a total of 150 tps with 4 sessions. But my office server is giving me max 30 tps with (4 sessions & above). Max 10 tps from each session. I installed kannel on as many as 6 diff servers in vps, there I am getting 150 tps at any vps. But I am restricted to 10 tps per session & max 30tps from my office server. kannel config, version, mysql all are same in all machines.
