Extremly poor network performance

Hello all. First time post, please excuse any annoyances.
I'm using a WRT300N Wireless-N Broadband Router connecting three (sometimes four) computers. Two wired and one (sometimes two) wireless, using 802.11G.
After a long period of time or after a short period of extremely high use (usually bit-torrenting assorted files) my network performance crawls to a near stop. My laptop will show an "excellent" connection but the speed will be 1 Mbps. The wired computers still show a connection of 100 Mbps but cannot connect to anything, including the router (using the web configure site). All connections time out. This happens to all the computers connected at the time and the only cure I've found thus far is to restart the router and or modem. If you need any more information please ask. Below is the information of my router, computers hooked to the router, and the network connection coming in.
Connection coming in the house:
Comcast Cable. 6 Meg connection (download)
Router:
WRT300N Wireless-N Broadband Router
Using the latest firmware (0.93.3)
Using DHCP, Laptop1 and Desktop1 have reservations.
Laptop1:
Broadcom internal wireless 'card' running 802.11G
Desktop 1:
Intel NIC
Desktop 2:
Asus motherboard onboard NIC
(occasional) Laptop2:
Dell external wireless card running 802.11G

I must apologize for one annoyance... the whole post. I skipped step one of posting by forgetting to use that handy-dandy "Search" box located just above this whole post deal, I apologize again. I've found (after searching) that this problem is actually quite common with the 300N and I assume it's a firmware issue, I then assume that Linksys is working day and night, sweating behind a monitor, sleepless and hungry because all they are doing is trying to resolve this issue... then again... you know what they say about 'assuming''.

Very poor network performance with a G4

I have a white & grey G4 (1.25GHz and 256MB) running OS X 10.4.5. It's exhibiting very poor network performance, e.g. it will not FTP files over a LAN at more than about 40KB/second.
Other nodes on the same switch perform fine, as do other ports on the switch. The machine is set to autodetect for speed & duplex, so my question is -- how do I debug this? I've tried swapping network cables already...
Thanks!
Chris

This came down to an incompatibility between the G4 and the Cisco. When the switch is set to force 100Mbit but negotiate duplex, the G4 doesn't like it. Going back to auto speed & duplex fixed the problem...

Poor Network Performance from VPN sites

We are experiencing poor network performance when connecting from hardware VPN sites. VPN sites have Cisco Hardware VPN client 3002 which terminates to Cisco 3005 VPN concentrator. Geting upload/download speeds of 355/484kbsp from VPN to surewest.com. If I remove the VPN and connect laptop directly to dsl modem, speeds are 3mb up and 1mb down. Any ideas what could be causing this?

Try this
Adjust the MTU and MSS size in concentrator and client.

Extremely poor ethernet performance?

If I burn a DVD from one Mac on the network to the MBP the network performance is so poor that even web pages stop loading and iTunes can't stream music. This is with 1000T ethernet.
Now I have plenty of other mac's on the network that are 5 years old and they handle it flawlessly.
Any else have ethernet problems when coping large files?

I'm not sure exactly what you are doing with a DVD, but the MBP has gigabit Ethernet which should transfer files very rapidly. Perhaps you could explain a bit more fully?
Is the rest of your network also gigabit? The cables, switches, etc?
If you look at your Network Utility (in /Applications/Utilities) what sort of Link Speed are you getting for your Ethernet connection? If you move the MBP to the connection being used by another computer that is getting high speeds, does anything change?
Let us know, we'll keep working on it with you.

Airport Extreme Poor WiFi Performance

I've been doing periodic bandwidth tests with speedtest.net for several years now. I have an account, so my results are saved. I do them from a Mac Mini and also from my iPad.
The MacMini is hardwired to an Airport Extreme. The iPad is, of course, using WiFi. Usually it is on the 5GHz network, but sometimes (I have no idea why) it selects the 2.4GHz network. The 5GHz network is "n only", the 2.4GHz network is b/g/n. Security is WPA/WPA Personal. The Airport Extreme is on firmware 7.6.1. (I rolled back in December, a couple of months after I noticed the degraded WiFi performance.)
Until mid-October of last year, the results on the iPad were similar to those on the MacMini.
For example:
On October 4 : iPad - 10.27 Mbps; Mini - 11.25 Mbps
On July 21   : iPad - 10.13 Mbps; Mini - 11.39 Mbps
However, beginning with tests done in late October, the results for the iPad are markedly inferior to those of the Mini:
On January 17: iPad - 00.49 Mbps; Mini - 06.14 Mbps
Today        : iPad - 00.87 Mbps; Mini - 08.69 Mbps
Oddly, when I switch the iPad to the 2.4GHz network, it does much better: 2.40 Mbps (today) But, still, much worse than before October and much worse than the Mac Mini. All the iPhones in the house are on the 2.4GHz network and get results similar to the iPad. However, none of them have as much test history saved.
I don't think it's a question of interference. None of my neighbors have 5GHz capable routers. On 2.4 GHz, I'm using channel 1. Both of my neighbors with routers are on channel 6. No cordless phones or other cordless devices in this house.
I have recently reset the network settings on both the iPad and iPhone.
So, what did I do to mess up the WiFi on my Airport Extreme?

Thanks.
Model is A1408.
I set the 2.4GHz network to channel 8.
I had to leave the 5GHz network to "Automatic" because choosing 36, 40 or 44 prevented both of my Airport Expresses from connecting. They would only connect with "Automatic".
All the names are alphanumeric and short: mgn, mgn5ghz, AirEx, etc.
I disconnected my MacMini's ethernet cable and just used WiFi. As expected, bandwidth decreased from the normal 10Mbps to about 2.8 Mbps.
I did not do a factory reset as family is about to come home and I don't want to be fiddling when they're expecting working WiFi. I'll do it tomorrow.

Lenovo W540 poor network performance

My company recently purchased a Lenovo W540 (Intel i7-4700MQ @ 2.4 Ghz, 16 GB RAM, Windows 8.1 pro 64-bit) for me to use when I am working remote. I have to say that this thing has been an albatross from day one. While it generally performs poorly, the wifi is the worst I have ever experienced. The W540 can only hit a fraction of the network speeds of my 4-year-old Dell Latitude E6400 (1.1 Mbps compared to 2.7 Mpbs on average). The connectivity is very unreliable and I am constantly losing my VPN and VoIP connections.
I have updated all of the drivers available from Lenovo and Intel as well as removed most of the bloatware pre-installed from Lenovo. Prior to doing so I could only manage .6 Mbps on a good day - using my tethered 3G phone was faster and more reliable.
I have contacted support twice to gain assistance. Their best offer was to have me drive an hour to the nearest service center for support.
I am at my wit's end and would appreciate any assistance you can offer before I send this back to Lenovo along with a jar of vasaline.
Solved!
Go to Solution.

Try uninstalling the wifi drivers from device manager before re-installing the latest version. My Intel 6300 card was sticking at 54mbps the other day too, and this seemed to fix it.

Extremely Slow Network Performance with 10.5.8

Let me start off by saying I don't use my mac mini much at all but when I do, the network is incredibly slow and unbearable. Half of the pages don't load, ipsw files for the iPhone take 20-30 minutes (with 15mbps interwebs)
My network setup:
1. Modem (provided by ISP)
2. 2 TB Time Capsule WPA2 security default settings.
3. Airport Connection
Now I would be for using 'openDNS' for a resolution but it didn't really improve the issue. Sure it sped up the internet on that machine, but I'm not willing to use a third party DNS when my MacbookPro connecting to the same exact network, doesn't experience this.
I have removed the hosts file for airport, remove the network connection, reset SMC, to no avail.
If anybody has any insight as to why my mac mini is the only device with poor performance, that would be greatly appreciated.

I shouldn't have to use another user.
Okay. It should also work with your current user but it's not.
For testing purposes and to narrow down the problem, try another user and see if it works.
If it works, it is something with the current user.
If it doesn't work, it is something with the system.

SOLVED:Poor networking performance (Slow site lookup)

I am dual booting with Windoze on the same machine. Websurfing performance on Arch is poor, and I can't figure out why. Windoze surfing with Firefox is instantaneous, whereas on Arch, I get "looking up http:www.google.com....................." for a good 5 seconds, sometimes 10 or 20 seconds, or more.
It will be fine for a few minutes, and then I get pretty bad stalls like that quite often.
Heres my rc.conf networking section:
lo="lo 127.0.0.1"
eth0="dhcp"
INTERFACES=(lo eth0)
# Routes to start at boot-up (in this order)
# Declare each route then list in ROUTES
# - prefix an entry in ROUTES with a ! to disable it
gateway="default gw 192.168.0.1"
ROUTES=(!gateway)
And my daemons:
DAEMONS=(@syslog-ng @hal @network @netfs @crond @alsa @fam @portmap kdm)
Any ideas?

You might try adding "alias net-pf-10 off" to /etc/modprobe.conf.
Tried this, and it did not work. Same lag when "looking up" sights.

The way I have it set up in my system, and works like a charm, is that I have the nameserver set in the router and in my system.
Ok, this seems to have worked. I plugged the DNS ip entries into the router and my resolv.conf, but DHCPD rewrites the resolv.conf on each reboot. I will consult the wiki to correct that, but even with just the DNS info in the router alone, I tried it out for a good 10 minutes and it was zippy fast, just like Windoze and PCLinuxOS (on my other HD).
I will wait a day before renaming the thread as "SOLVED", so I can test ouit the results more thoroughly.
Now, can anyone explain why it works fast under Windoze and PCLinuxOS, but Arch needs the DNS settings? Or is it just one of those weird unexplainable things?
I am using a D-Link router, if it matters. (IIRC, some routers actually use Linux.)

Extremely poor load performance into RDF store

We are seeing unacceptably poor performance loading our RDF models. We have triedloading with Jena adaptor as well as loading using the BatchLoader class. Either way, the absolute best rate we have seen is about 20000/minute. Here are the specs:
Loading a triples file from disk which contains 5.08 million triples
Oracle 11gr2 running on Enterprise Linux64 with 16 GB RAM
Oracle 11gr2 running on Solaris 10 with all the latest patches and packages...64 bit with 8GB RAM
Sun is a bit slower than linux, but both are quite poor. I can load the identical triples file into Allegro running on my desktop PC and consistently get load rates of 1 million per minute.
Can anyone suggest what could be causing this performance issue? Oracle is a very recent install on both the sun and linux boxes, and there is nothing whatsoever running on either one other than oracle, and I am the only oracle user. All install and parameter settings are oracle default.

An update on the stats. I changed the way models are created, doing it manually from sqlplus first (vs letting the Jena stuff create the model on the fly), and that made things run about 3 times faster, but I still am not seeing anything better than triple load times of 79K/minute.
Here is the java that runs the load:
String model = "GMI";
oracleGraph = oracleTools.makeGraph(model);
oracleModel = new ModelOracleSem(oracleGraph);
InputStream is = FileManager.get().open(props.getProperty(model +".NTRIPLES_IND_FILE"));
StopWatch timer = new StopWatch();
timer.start();
// read file contents into oracleModel
oracleModel.read(is, "", "N-TRIPLE");
timer.stop();
is.close();
System.out.println("\nLoad time into Oracle: " +timer.getElapsedTimeSecs());

Extremely poor WiFi performance...

I got my touch (8gb) yesterday, and i've noticed my wifi performance is terrible. At home, on my wireless AP (802.11g), pinging the touch i notice at least 10% packet loss, and latency all over the place. At work on our 802.11b AP I see about 60% loss. I've tried every channel on both AP's to rule out interference.
If i let it go to sleep, when waking back up it's responsive for about 10 - 15 seconds, then takes a dive.

Browsing works during the brief period where it responds to ICMP, then it's nearly impossible to browse. It's not near as bad on my home connection though.
Any ideas other than replacing? I'm going to cruise around and try to find some open AP's to test on later today just to be sure it is defective hardware and not compatibility issues with the APs.

Extremely poor internet performance 1841

**Edit**
To add more to this, somehow I missed it but I had quite a few CRC errors on the outside interface. I switched the FastEthernet0/0 to speed auto, duplex auto and now I am getting about 45Mbps download speed. I would still like to see the router get closer to 60 though, is there anything I could tweak in the config that might increase the speed of this just a little bit? Or is an 1841 only rated to about 45Mbps with all the firewall features turned on?
**End Edit**
A school I am doing some volunteer work for has a 60/4 coax internet service through Charter communication. I just put in an older Cisco 1841 router and used my default standard config I use at many other sites. For some reason I am only getting about 6 - 8 mbps download speeds with the router. When I plug directly into the cable modem with my laptop I am getting the advertised speeds.
Attached is my config, it looks pretty standard to me and for the life of me I can not see why this router would be performing so poorly. The CPU utilization is very low, I have to be missing something though.
Thank you everyone

I'm having the same issue with the 1841 I get about 12Megbit were I can get over 20 connected with a cheap old linksys router. If you look at the processor it's pegged at 100% after doing some research I found the 1841 has a slow CPU it's max is only 38meg that's not even natting. I assume when you nat the CPU is maxed out. My IP input shows 70% while downloading a 500meg file. I'm going to try an ASA5200

Hyper-V Windows 2012 r2 Poor network performance

Hi,
Since that I installed Windows 2012 R2 and Hyper-v, I notice that is very slow performing copy operations from the VMs to the physical machine (appears to be lock to 10MB). Firs I though that this issue was only between the VMs and the parent OS, now I realized
that when copying between this Hyper-v physical host and another physical host in the same subnet I also get only 10MB of speed.
How do I unlock this 10MB limit??
The switch and all NICs are GIGABIT capable and before using Windows 2012 r2, using the same hardware boxes I was doing 400MB of transfers between physical hosts and VMs??!!
Thank you.

I had the exact same issue with the same AR8151 NIC on my Alienware, only I'm running Windows 8.1.
I have a VM with both an external (to the AR8151) and an internal NIC which serves as both a domain controller and router (RRAS) for my other VMs (which only have Internal interfaces). There is no VMQ setting on the adapter, and I messed around with
the offload/RSS settings, but performance would drop whenever this VM would be running. (Internet speed test would go from 95Mbps downstream to about 24Mbps.). When I paused or shut down the VM, performance would return to normal.
I found the issue to be an errant entry in my route table which I have no idea how it happened. A second default route was created which used the internal IP of the VM with a lower metric. Simply deleting the route corrected the performance issue.

Extremely Poor Read Performance

Hey guys,
For a work project, I have been instructed to use a Berkeley DB as our data storage mechanism. Admittedly, I know little about BDB, but I've been learning more in the past day as I am reading up on it. I'm hoping, though, that even if no one can help me with the problem I am having, they can at least tell me if what I am seeing is typical/expected, or definitely wrong.
Here's what I got:
- Parent table A - Has 0 or 1 key for table B, and 0 or 1 key for table C
- Table B
- Table C
For purpose of discussion, let's ignore table C as it is logically the same as Table B.
Table B has 25 million rows, keyed by a 34-36 digit string, and a payload of 500-1000 bytes.
Table A has 26 million rows, 25 million of which reference the 25 million rows in Table B.
My question is not on the merits of why the data is structured the way it is, but rather about the performance I am seeing, so please refrain from questions such as "why is your data structured that way - can you structure it another way?" I know I can do that - again I just want to know what other people are experiencing for performance.
Anyway, what's happening is this - my program runs a cursor on Table A to get all records. As it gets each record in Table A, it retrieves the referenced records in Table B. So, the cursor on table A represents sequential key access. The subsequent retrievals from Table B represent "random" retrievals - i.e. the key may be anywhere in the index, and is not at all related to the previous retrieval.
Cruising the cursor on Table A, I am seeing performance of about 100,000 records per 2 seconds. However, when I add in the retrievals from Table B, performance stoops all the way down to 100,000 records per 1000 seconds, or better put 100 per second. At this rate, it will take nearly 70 hours to traverse my entire data set.
My question is, am I simply running into a fundamental hardware issue in that I am doing random retrievals from Table B, and I cannot expect to see better performance than 100 retrievals per second due to all of the disk reads? Being that the DB is 20 GB in size, I cannot cache the entire table in memory, so does that mean that reading the data in this fashion is simply not feasible?
If it isn't feasible, does anyone have a suggestion on a different way to read the data, without changing the table relationship as it currently stands? Considering Table B has a reverse reference to table A, I've considered putting a secondary index on table B so that instead of doing random seeks into table B, I can run a cursor on the secondary index of table B at the same time I run the cursor on table A. Then, for each record in table A that has a reference to table B, the first record in the cursor for table B should be the one I need. However, reading about secondary indexes, it looks like all a secondary index does is give a reference to the key to the table. Thus, my concern is that running a cursor on the secondary index of table B will really be no different than randomly selecting the records from table B, as it will be doing just that in the background anyway. Am I understanding this correctly, or would a secondary index really help in my case?
Thank you for your time.

Hi Brett,
Is the sorting order the same between the two databases, A and B, that is, are the keys ordered in the same way? For example, to key N in database A, key N in database B is referred.
I would guess not, because you mention the "randomness" in retrieving from B when doing the cursor sequential traversal of A, and the 34-36 digit keys in B are probably randomly generated.
With B as a secondary database, associated to A as the primary database, it would make sense having a cursor on secondary database B to iterate, if you expect that the same ordering of keys in A (as mentioned in the beginning of this post). For example, you would use DBcursor->get to iterate in the secondary database B, or DBcursor->pget if you also want to retrieve the key from the primary database A: DBcursor->get(), DBcursor->pget()
Basically secondary indexes allow for accessing records in a database (primary db) based on a different piece of information other than the primary key:
Secondary indexes
So, when you iterate with a cursor in B you would retrieve the data from A (and in addition the key from A) in the order given by the keys (secondary keys) in B.
However, a secondary database does not seem to me feasible in your case. You seem to have about 1 mil records in primary db A for which you would not have to generate a secondary key, so you would have to return DB_DONOTINDEX from the secondary callback: DB->associate()
(it may be difficult to account exactly for the records in A for which you do not want to generate secondary keys)
Also, the secondary key, the 34-36 digit string, would have to somehow be derived from the primary key and data in A.
If the ordering is not similar (in the sense explained at the beginning of the post) between A and B, then having the secondary index does not too much value, other than simplifying retrieval from A in queries where the query criteria involves the 34-36 digit string.
Back to your current way of structuring data, there are some suggestion that could improve retrieval times:
- try using the latest Berkeley DB release, 5.1.19: Berkeley DB Release History
- try configuring a page size for the databases A and B equal to that of the filesystem's block size: Selecting a page size
- try to avoid the creation of overflow items and pages by properly sizing the page size -- you can inspect database statistics using db_stat -d: db_stat
- try increasing the cache size to a larger value: Selecting a cache size
- if there's a single process accessing the environment, try to back the environment shared region files in per-process private memory (using DB_PRIVATE flag in the DB_ENV->open() call);
- try performing read operations outside of transactions, that is, do not use transactional cursors.
For reference, review these sections in the Berkeley DB Reference Guide:
Access method tuning
Transaction tuning

Extremely poor delete performance on DS 5.2sp4

I'm trying to run some bulk deletes on our production master server (5.2 sp 4), and we're having problems with the performance. Strangely, the problem doesn't seem to manifest on the replicas.
Below is a section from the logfile. I sent ten deletes using ldapdelete -f.
The first five go very quickly, then apparently, the server decides to do some "housekeeping" and "goes away" for nearly five minutes. The next five are quick to return, then the unbind, but the "housekeeping" continues on the server for nearly five minutes.
During those five minutes, disk usage is very high (the disk the ldap db's are on is normally very lightly used).
Suggestions?

I'm seeing exactly the same here. I have a perl script that is attempting to delete users (we have around 12000 to delete) and after the first 5 it clags up and takes ages (considerable cpu usage increase as well).
I could turn of the referential integrity plugin I guess (although that will result in a break in service so is a bit of a problem) but we do really want this working.
All of the attributes refered to in the plugin config are indexed for equality (at least).
Anyone have any ideas why this struggles? Performing an ldapsearch with what I assume would be the same filter returns instantly (with the correct results!)
(|(member=uid=dmc,ou=staff,xxx)(uniquemember=uid=dmc,ou=staff,xxx)(owner=uid=dmc,ou=staff,xxx)(seeAlso=uid=dmc,ou=staff,xxx)(nsroledn=uid=dmc,ou=staff,xxx)(iplanet-am-modifiable-by=uid=dmc,ou=staff,xxx)(iplanet-am-static-group-dn=uid=dmc,ou=staff,xxx)
We are running 5.2P3. Is there something special that I'm missing? (an index that the plug needs but an ldapsearch won't or something?). I'm scratching my head here... a truss of the slapd I'm connected to show a huge amount of reads so I assume it is searching the entire db and not using the indexes - why would this be??

Extremely poor .tag performance

Hi,
          Has anyone else noticed a severe performance decrease (WLS 9.2) when using .tag files inside a jar file versus .tag files in WEB-INF/tags ?
          We recently migrated our JSPs from using WEB-INF/tags and @tagdir to using the @uri attribute (and move the .tags to META-INF/tags inside a jar). Now we are seeing up to 20 seconds additional load time on even the most simple of JSPs!
          I'ld like to enable some debug settings to see what exactly the server is doing during those 20 seconds, but i couldn't find the right debug category to enable amongst the myriad of available categories.
          Any thoughts ?
          Regards,
          Jorg
