I’m looking for help with what I’m sure is an age old question. I’ve found myself in a situation of yearning to understand network throughput more clearly, but I can’t seem to find information that makes it “click” We have a few servers distributed geographically, running various versions of Windows. Assuming we always use one host (a desktop) as the source, when copying data from that host to other servers across the country, we see [...]

I have a dedicated server setup that has just started causing us issues. Our immediate problem, is that last week, could log into an admin page of one of our websites just fine, now we can’t. It does do a heavy SQL procedure on the SQL database, but as its only a small usage site, im ok with that. The problem the website is timing out, and the admin’s can not log in. It seems [...]

I was wondering if you can throttle/boost the download speed from my VPS to me, because now and often I download a database which is quite big, typically 5-7GB. My side is quite slow (typically I have max speeds of 100Kb/s) so I was wondering if it’s possible to throttle the bandwidth speed from my server to me that it could make the download much faster. If this is possible, how can I do this? [...]

I’m contemplating moving datacentre and I need to know the size of pipe I’ll need in order to get a quote. Currently I’m charged on GBs of traffic per month (currently about 42GB inbound – so requests only) but the new mob would rent me a pipe instead and the size of it determines the price. I have a number of Centos web servers and one database server behind a loadbalancer; the webservers access the [...]

I was looking around. It found 100mbps to be the fastest speed listed. Is that the fastest? What is the name of this connection and what should i google to learn more? 40Gbit/s QDR Infiniband is probably the fastest single link network connection you can find. With DWDM (so that’s multiple wavelengths over a single fiber link), you can have over 160 10Gb/s links, so I’ll let you do the math. Check more discussion of [...]

I have Apache server 2.2.21 on my OSX Lion 10.7.2 64 bit. is there a way to control to download speed? I’m testing it locally and every download happens very quick. is there a way to control the download speed to make it slower so it will feel like I’m downloading the files from a slow server? Perhaps you can use mod_bandwidth for this? Check more discussion of this question. Bookmark on Delicious Digg this [...]

I am thinking about setting up a server for multiple clients to log in to (2 at the same time max), so that people away from the office can use our (resource hogging/CPU intensive) design software over our VPN. My questions are as follows: Is it even possible to get a good enough response time over the internet? (all internet connections are at 25mbps or faster, internally we run on gigabit) Windows or mac? What [...]

Obviously it’s just one factor in the mix, but if I host a site here in the UK knowing that the majority of my users are in the U.S., how much weight should I give concerns about access speed for those users? (Currently ~70% U.S. users, ~20% UK, remainder are all over.) Trans-Atlantic hops used to be a bit of a big deal, but is it really much of a factor in today’s world? Again, [...]

We’re diagnosing a speed problem between our shenzhen office and our asset management server. It seems stupid, but I need to get the data in the same format. How do i convert the MBps that isp’s quote, and that tools like speedtest.net spit out, and convert that the k/s my management are used to seeing on firefox and ie? The google suggestion is a good one. This “old way” is useful in generic unit conversions [...]

Our company is buying some HP Procurve managed gigabit switches to replace some of our core switches. However, we aren’t able to upgrade all of our switches from 100Mb to Gigabit switches. I think I know the answer but I’m not exactly sure. If we plug those 100Mb switches (or even a 100Mb device) into those Gigabit switches, will the performance of the entire switch drop to 100Mb or will just that one port work [...]
