I noticed that there are huge pings to my server from time to time, example:
------------------ 64 bytes from HOSTNAME (server-IP): icmp_seq=0 ttl=60 time=2.93 ms 64 bytes from HOSTNAME (server-IP): icmp_seq=1 ttl=60 time=2.70 ms 64 bytes from HOSTNAME (server-IP): icmp_seq=2 ttl=60 time=1901 ms 64 bytes from HOSTNAME (server-IP): icmp_seq=3 ttl=60 time=899 ms 64 bytes from HOSTNAME (server-IP): icmp_seq=5 ttl=60 time=2.69 ms 64 bytes from HOSTNAME (server-IP): icmp_seq=6 ttl=60 time=2.62 ms 64 bytes from HOSTNAME (server-IP): icmp_seq=4 ttl=60 time=2132 ms 64 bytes from HOSTNAME (server-IP): icmp_seq=8 ttl=60 time=2.57 ms 64 bytes from HOSTNAME (server-IP): icmp_seq=7 ttl=60 time=1190 ms 64 bytes from HOSTNAME (server-IP): icmp_seq=10 ttl=60 time=2.65 ms 64 bytes from HOSTNAME (server-IP): icmp_seq=9 ttl=60 time=1048 ms 64 bytes from HOSTNAME (server-IP): icmp_seq=12 ttl=60 time=2.74 ms 64 bytes from HOSTNAME (server-IP): icmp_seq=11 ttl=60 time=1205 ms ------------------
First I thought that it is network related, but most strange for me was that I did not have any packets lose.
Then I tried to ping from my server to other hosts - situation was the same - some ping were good and some were huge (700ms, 800ms, even 2000ms)
I checked: cat /proc/sys/net/ipv4/netfilter/ip_conntrack_max and it was 65536
Then I checked: cat /proc/sys/net/ipv4/netfilter/ip_conntrack_count and it was ~1600 so normal.
I did not have such dropped information on all my other servers. Dropped counter for RX was constatnly increasing.
So I decided to restart all services on the server. After restarting network and ipaliases - problem disappeared. RX dropped counter is still rising, but I do not have any slowdowns on the server and pings are normal.
My question is - does anyone could have any idea what can casue my problem and how can I prevent this in the future?
we have 9 rack each rack have 2 cisco switch 2950(1 for internet and 1 for private network) if we try to do a transfer files between two server we can't go over 1mbps, the same if we move the file from the web, every server nic is set to 100mbps the same for swith port, why we get a so slow speed?
I have mounted NFS part. but when copying a big file the speed is OK like 5-6MB/s but when starting to copying all other (small files) speed is like 20-200KB.s What is the reason and is it way to improve the speed or use other way to mount drive remotely and preserve the same permissions after backup?
I moved from shared host to VPS a few days back. Since the move, the site becomes slow during particular time of the day. It appeared to be an issue of cron run by their another client and after promising that they would move that client to another node (I have spent more than 25 days to follow up on this till now) they backed off from their words but informed me about an alternative. Now, they say that the cron of that client was executing many scripts and they have spaced those scripts.
I am looking for a long-term host and was wondering:
1. VPS provides a minimum guaranteed stuff so what is the use of that guarantee if one client can make the server crawl (imagine 5 minutes or more to open a site).
2. Can a host be trusted who does not honour words.
I have just gotten a new server and the ping results were pretty fine. However, when it comes to the download speed its horrible. What could be the issue?
Hi got an image server with volumedrive but very disappointed about the speeds.
I ordered a 100mbps.
In Lighttpd server-status it cannot go more then 1.10 Mbyte/s...
but at PacificRack the same amount of traffic easily does 2.5Mbyte/s and in past has done 4Mbytes/s not even sweating.
Am I on 10mbps or 100mbps?
I ran mii-tool and it says eth0: negotiated 100baseTx-FD, link ok
I haven't even used my server at all for a few minutes because everytime I want to use it the connection is too slow that I need to change back to PacificRack.
I'm on a NetDepot 10 meg unmetered and just started migrating some accounts over from The Planet. I've been with them since... well the beginning. I wanted something a little less expensive with more bang for buck.
While the uptime has been good. The network speeds have not. I'm never getting more than sustained transfer speeds (scp, rsync) from my Planet server of 400KB/s... at this rate it's going to take 6 hours to transfer an account that's just 8 gigs in size.
NIC is set to 100 meg, full duplex. Both servers have just about no activity on them and firewalls clear. 3% 323MB 378.9KB/s 6:02:15 ETA
Is anyone else finding the network speeds with NetDepot sluggish? I submitted a support ticket about this.
This makes things like remote backups impossible.. hopefully it's just a issue with an overused switch or something. The worst part is I did the full buy-down package in hopes of being with them long term, now I'm not so sure.
I am copying 6 GB of data to a machine across a 100baseTX (full-duplex) link. There are no collisions on the network, yet scp and systat -ifstat are both reporting extreamily slow transfer speeds... around 400 KB/s. That cant be! What what can I do to fix this?
I'm running FreeBSD 6.2. What other stats should I be looking at to figure this out?
why I am not getting at least 9 MB / sec, let alone 12?
I have a server in Liquidweb with 50GB of web pages and I want to move this accounts to my servers in Europe. The problem is that speed is about 4Mbps and becomes impossible to move the accounts.
With my other servers in GNAX I have not had trouble getting speeds of 80/100Mbps.
I tried to move my server of Liquidweb to GNAX but has reached only 14Mbps.
Which is the best solution? The network liquidweb has always been very stable, but I am seeing that is really slow.
We've got a discounted Quad dedi box from Ecatel.net about a week ago. Their network and prices are really good, sure. But we still have problems with start up because the second hdd isn't mounted or installed properly. The support team has answers about 1-2 times per day only so this question is in progress already for days.. The helpdesk is locked somehow from todays morning (I see our account is present but there's no way to log in) and we are still waiting for replys from day-before-yesterday requests...
I wouldn't like to be some kind of sharp under any circumstances and I respect every business but this is probably too long so we have to pay now just for waiting to get a server ready with no start yet.
Does somebody work with them? Is it normal situation? We still have some boxes in Layeredtech and would like to move to European DC (these boxes are middle-ended so we need more power now). There were no such problems in LT. Never. The maximum response time to such kind of questions was 2-5 hours (15 minutes in general), maybe a bit more (for hardware setup requests), but not days and nights with no progress indicator.
Maybe that is a European DC highlight strategy to have such delays with tickets response, isn't it? Coz the European market is new for us, anyway, we've never had boxes there before but would like to.
I've got 25 domains on a Virtuozzo/Plesk8.6/CentOS5 VPS. Each domain has one up-to-date install of WordPress, most have very little traffic (average 200mb per month), maybe 2 domains get 5-7gb traffic per month.
I monitor port 80 connections and rarely see more than 10 at a time. That should in my opinion be no problem at all for a VPS with 768mb guaranteed ram and 2.4ghz cpu. I've got 30gb hard drive spare too.
But.... about 8 or 10 times a day it grinds to a complete halt: server load at 500-1000%, sites timing out, plesk takes 3mins to load, often I can't even connect with SSH, and the plesk web server, apache
80 seconds sounds like a huge amount of time for a MySQL insert to me! Does anyone know if this is likely to be the cause of my trouble? Some problem with Plesk and the database? Or could it be something else?
I've two shared hosting accounts, one is hostgator and other is godaddy.
I've uploaded a file (.flv) on hostgator and same file on godaddy.
here a link to both
Hostgator flv
Goddady flv
Now i am use a Download manager " free download manager" to download files The hostgator file downloads at 17-35kb/s The godaddy file downloads at 200kb/s
I am using 2Mbps dsl.
Also my hostgator cpanel loads slow. and other files are downloads at very low max 40kb/s.
What are the issues. I've contacted hostgator support and they say that every thing is ok on their end.
I have to stream videos on hostgator but the speed is too slow. and it buffers alot.
What would be best method to test quality of server?For example,how site loads,do they load at all,speed of loading,etc.
What bothers me some of my site which i host on my servers start to lose traffic a lot lately.It could be beacuse of summer slowdown,but i simply cant belive in that.
Maybe server have a downtime or server have bad hardware router which doesnt accept all traffic.In shortly i belive something is wrong.So please tell me how do i do deep scan/check of all my servers.
I have a dedicated server, but i dont know how i can measure the bandwidth at specific time, the problem that i feal that my bandwidth is below what i requested...
what i mean with Bandwidth is not trfic, it is the connection speed at a moment (i.e. 50Mbps)
the speed of FTP access to the server is acceptable, if I surf the website on the server by ip address, the speed is also acceptable however, if I surf the website on the server by domain, the speed is really slow.
I have two servers one from hostmysite and other one is from 15minute server, I would like to know which one is faster, I have a dedicated server from 15minuteserver, but sometime I get slow speed I am not really sure which one is faster.
