Do you have performance issues on the VPS?
Hello, Last weekend i tried to move a high traffic website to a VPS on the same hardware that i was running it before. I have set the ubc and other parameters like this: # UBC parameters (in form of barrier:limit) KMEMSIZE="999999999:999999999" LOCKEDPAGES="256:256" PRIVVMPAGES="524288:643072" SHMPAGES="21504:21604" NUMPROC="2000:2000" PHYSPAGES="0:9223372036854775807" VMGUARPAGES="524288:524288" OOMGUARPAGES="524288:524288" NUMTCPSOCK="999999999:999999999" NUMFLOCK="999999999:999999999" NUMPTY="16:16" NUMSIGINFO="1024:1024" TCPSNDBUF="999999999:999999999" TCPRCVBUF="999999999:999999999" OTHERSOCKBUF="999999999:999999999" DGRAMRCVBUF="262144:262144" NUMOTHERSOCK="999999999:999999999" DCACHESIZE="3409920:3624960" NUMFILE="999999999:999999999" AVNUMPROC="180:180" NUMIPTENT="800:800" # Disk quota parameters (in form of softlimit:hardlimit) DISKSPACE="211048576:211153024" DISKINODES="400000:440000" QUOTATIME="0" # CPU fair sheduler parameter CPUUNITS="153424" After a while running it ( it's the same OS, same apache version and conf, same mysql conf etc. ) the apache processes stops working and use a lot of CPU ( load goes up to 400-500 ). If i strace one of the processes, they do not show anything. Also, the apache logs are not updated the this starts to happen. It is important to note that user_beancounters do not show any failcount, but the system is unusable. We have about 400 requests per second, but our current hardware was running fine until me moved to a VPS. Do you see any configuration issues at my ubc parameters? Could the diskinodes limitation be causing this problem ( limiting apache access to disk and making it goes crazy? )? Anyway, any opinions and experiences about this issue are welcome Thanks!
Re: Do you have performance issues on the VPS?
what you get if you check in vps: df -i
Hi, please report the beancounters (resources), ioacct and vmaux of this container like: $ cat /proc/bc/<CTID>/{resources,ioacct,vmaux} Bye, Thorsten
