August 17, 200916 yr Memory usage. I'm noticing a considerable spike in memory usage. I have 3GB of RAM and it's using every single solitary bit of it. This is causing horrible streaming problems for video and stuttering to occur. op - 22:51:14 up 4:05, 1 user, load average: 2.37, 2.18, 2.13 Tasks: 72 total, 2 running, 70 sleeping, 0 stopped, 0 zombie Cpu(s): 2.7%us, 22.3%sy, 0.0%ni, 53.7%id, 20.9%wa, 0.2%hi, 0.3%si, 0.0%st Mem: 3115880k total, 3026248k used, 89632k free, 34824k buffers Swap: 0k total, 0k used, 0k free, 2909136k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 1502 root 20 0 14324 4748 3540 S 2 0.2 3:53.32 smbd 1430 root 20 0 55464 3708 548 S 22 0.1 56:04.68 shfs 1290 root 20 0 12692 3256 2524 S 0 0.1 0:00.03 smbd 1288 root 20 0 8308 1772 1196 S 0 0.1 0:00.09 nmbd 1511 root 20 0 7180 1728 1364 R 0 0.1 0:00.02 in.telnetd 1295 root 20 0 12692 1672 940 S 0 0.1 0:00.00 smbd 1296 root 20 0 53772 1520 1124 S 0 0.0 0:01.87 emhttp 1512 root 20 0 2428 1304 1052 S 0 0.0 0:00.01 bash 1240 root 20 0 3980 1212 940 S 0 0.0 0:00.01 ntpd What I am doing: bitorrent-2 downloading 1 uploading utorrent. Streaming an AVI (not mkv) That's it. no other file transfer or massive activity. I'm on a gigabit network and it's showing full gigE: eth0: negotiated 1000baseT-FD flow-control, link ok both my computer (WinVista x64) and this server are just going slow. I can't get full gig line speed as I'll hit 100mbps (bit not Bytes) i'm lucky to hit 60mb which there's no way it should be going that slow. Any idea what is going on or is this some quirk with 4.5b6?
August 18, 200916 yr It is not uncommon for a linux system to use all unused ram for buffer cache (as you see in the cached colum). I noticed the system is at 21%WA (waiting for I/O). Reads or writes. I also noticed the shfs us at 22% cpu. This makes me think something is reading or writing to a user share fairly often keeping it a bit busy. How is your torrent configuration set up? Is it on the local machine or a remote machine on the network. Keep in mind the torrent client is reading little bits of files here and there to serve clients or writing randomly to one or more files. All of this repositioning chttp://lime-technology.com/forum/index.php?action=post;topic=4191.0;num_replies=0ould cause demands on the network or user share. I have my torrent client lhttp://lime-technology.com/forum/index.php?action=post;topic=4191.0;num_replies=0ocal on unRAID with rtorrent. I also use a direct disk share so the user share does not come into play for anything. If you are still having stutter issues, try redirecting the movie you are reading to use the disk share instead and see how it goes. http://lime-technology.com/forum/index.php?action=post;topic=4191.0;num_replies=0 Next test would be to check the network speed out with something like nttcp. This only tests the network layer and not the filesystem sharing layer. http://sd.wareonearth.com/~phil/net/ttcp/ http://www.pcausa.com/Utilities/ttcptxdown.htm C:\tmp>pcattcp -t atlas PCAUSA Test TCP Utility V2.01.01.08 TCP Transmit Test Remote Host : atlas Transmit : TCP -> 192.168.1.179:5001 Buffer Size : 8192; Alignment: 16384/0 TCP_NODELAY : DISABLED (0) Connect : Connected to 192.168.1.179:5001 Send Mode : Send Pattern; Number of Buffers: 2048 Statistics : TCP -> 192.168.1.179:5001 16777216 bytes in 0.30 real seconds = 55164.98 KB/sec +++ numCalls: 2048; msec/call: 0.15; calls/sec: 6895.62 C:\tmp> root@Atlas /boot/custom/bin #nttcp -r ttcp-r: buflen=65536, nbuf=2048, port=5001 tcp ttcp-r: socket ttcp-r: accept from 192.168.1.16 send window size = 65536 receive window size = 87380 ttcp-r: 16777216 bytes in 1.31 real seconds = 12525.86 KB/sec = 100.2069 Mb/s ttcp-r: 7219 I/O calls, msec/call = 0.19, calls/sec = 5519.05 ttcp-r: 0.0user 0.0sys 0:01real 3% 0i+0d 0maxrss 0+8pf 6662+1csw and then in the other direction C:\tmp>pcattcp -r PCAUSA Test TCP Utility V2.01.01.08 TCP Receive Test Local Host : rgcxp ************** Listening...: On port 5001 Accept : TCP <- 192.168.1.179:41580 Buffer Size : 8192; Alignment: 16384/0 Receive Mode: Sinking (discarding) Data Statistics : TCP <- 192.168.1.179:41580 134217728 bytes in 1.81 real seconds = 72335.54 KB/sec +++ numCalls: 17090; msec/call: 0.11; calls/sec: 9431.57 root@Atlas /boot/custom/bin #nttcp -t 192.168.1.16 ttcp-t: buflen=65536, nbuf=2048, port=5001 tcp -> 192.168.1.16 ttcp-t: socket ttcp-t: connect send window size = 65536 receive window size = 87380 ttcp-t: 134217728 bytes in 1.83 real seconds = 71743.85 KB/sec = 573.9508 Mb/s ttcp-t: 2048 I/O calls, msec/call = 0.91, calls/sec = 1121.00 ttcp-t: 0.0user 0.1sys 0:01real 8% 0i+0d 0maxrss 0+15pf 2283+2csw
