Hi Alex, Thanks for your suggestions. Yes we’ve tested the underlying storage. We specifically upgraded drives on the particular testing server I am using at the moment, and are using a ZFS volume.
But to answer your specific questions, # hdparm -t /dev/sda2 /dev/sda2: Timing buffered disk reads: 4118 MB in 3.00 seconds = 1372.43 MB/sec Also, %iowait remains at 0. I did see it briefly go to %0.13 for one cycle when I sent 2000 simultaneous registrations to Kam. It doesn’t appear to be the disk subsystem.

That’s the only place that I know. Have you tested your storage throughput? Even something as simple as `hdparm -t /dev/sda`[1]? What about monitoring background I/O demand, i.e. `iostat -x 1`? Look at the %util on the drive being written to. I know you said your log isn’t being written to the local disk, but other storage activity could still be pushing up your I/O base load. — Alex [1] Replace `/dev/sda` with your actual storage device. -- Alex Balashov | Principal | Evariste Systems LLC Tel: +1-706-510-6800 / +1-800-250-5920 (toll-free) Web: http://www.evaristesys.com/, http://www.csrpswitch.com/ __________________________________________________________ Kamailio - Users Mailing List - Non Commercial Discussions * [email protected] Important: keep the mailing list in the recipients, do not reply only to the sender!
