Search Again: Re: Slow server performance From: Andreas Carlsson Date: Wednesday, July 9, 2003 Time: 5:13:09 pm I have serious problems accessing the webserver, so I can't read the logs. I made some Top's though and noticed that Server Settings (I'm on OS X) is taking around 100% all the time (it's a dual 1 GHz). Is that normal? However, I made some Ping statistics as well; My conclusion is that, that everything on the DSL wire is making heavy packet losses. Since I'm quite new to this I don't really know how much is much, but I made some comparements: ROUTER AT OFFICE: --- 62.181.204.82 ping statistics --- 609 packets transmitted, 383 packets received, 37% packet loss round-trip min/avg/max = 37.459/42.488/127.62 ms DNS1 --- 62.181.204.83 ping statistics --- 669 packets transmitted, 411 packets received, 38% packet loss round-trip min/avg/max = 34.842/38.91/137.342 ms DNS2 --- 62.181.204.84 ping statistics --- 656 packets transmitted, 531 packets received, 19% packet loss round-trip min/avg/max = 34.354/38.131/129.059 ms WEBSERVER: --- 62.181.204.85 ping statistics --- 642 packets transmitted, 550 packets received, 14% packet loss round-trip min/avg/max = 34.487/38.163/190.505 ms MAILSERVER: --- 62.181.204.86 ping statistics --- 635 packets transmitted, 503 packets received, 20% packet loss round-trip min/avg/max = 35.059/40.731/150.434 ms SUNET IN SWEDEN --- 192.36.125.2 ping statistics --- 573 packets transmitted, 571 packets received, 0% packet loss round-trip min/avg/max = 23.266/25.201/174.237 ms ANOTHER DNS IN SWEDEN: --- 212.181.63.104 ping statistics --- 611 packets transmitted, 603 packets received, 1% packet loss round-trip min/avg/max = 26.877/31.153/168.83 ms BROADBAND PROVIDER'S GATEWAY: --- 62.181.204.81 ping statistics --- 634 packets transmitted, 527 packets received, 16% packet loss round-trip min/avg/max = 32.396/40.289/566.127 ms Is there some way to ping just the http port etc? Any thoughts are welcome, I am clueless. Thanks, /andreas Len Conrad wrote: >>Question is; What kind of problem?
