Troubleshoot a Slow Network – Slow Server

Slow Server

How do we know the server is slow and the problem is not elsewhere?
Make a file transfer between any two other computers on the network. Compare the measurements with the server’s transfer rates.
What are the reasons for a slow server?
There are many reasons for a slow server. The server is many times the bottle-neck of a network. Here are a few reasons for a slow server:
An average, or below average network card, (you need good quality network cards for a server).
Server Network Card Underutilized. Connect your server on the backbone or on 1GB switch ports to make use of the high speed network card. You probably want to limit all your clients to transfer at 100Mb so that there is no traffic discrimination. If your server and switches support higher transfer rates, (10GB ports), make sure you make use of it.
Slow disks. Poor hardware is many times the main reason. Improper configuration, such as choosing the wrong RAID type, or not using write caching can be another reason.
Too many clients on a server. If too many clients make requests to the same single server this could overload the server and it will perceived as a slow network by the users. Measure your server’s performance on load using the performance logs and alerts and the system monitor in Windows. Usually the performance is changing over the course of a day based on the number of users who access the server at the same time. Sometimes adding another network card would be sufficient. Enabling cache writing on the SCSI card can help a lot, (make sure you install a cache battery), adding a new SCSI card and additional disks to offload the existing ones could be of help. Sometimes adding another CPU can make a difference, (if you have free CPU slots). Memory is very often the most used method of upgrading, but most of the times it is not the needed solution. Use the performance logs and alerts and the system monitor and compare with the recommended thresholds to determine what your bottleneck is.
Slow server response, (packet sniffer to determine the handshake time), Adjust the server’s configuration to optimize the handshaking time; (this is a fairly advanced optimization task).

Internet Business – How to choose your First Web Hosting Company

The Internet Business is a business model that can be started with a minimum of investment. Your work, talent and favourable circumstances can be enough to help you start an Internet business.

If you already have an idea and you planned everything about your product and site’s content you need to start your business. At first you need to minimize the costs and investments in order to diminish risks. If the business will not take off as expected the loss will be minimal and you can try another idea. Read this article about successful business ideas.

The minimum for an Internet business is a domain name, (this is not 100% required but strongly recommended) and a Web Server. A web server can be your own equipment or hosted server. Hosting companies will sell various types of hosting services ranging from a dedicated server with one or more dedicated IP addresses to shared hardware.

A good web hosting package will contain support for application development platforms such as PHP, ASP, ColdFusion, etc… access to a database server and a Control Panel that offers to customers an easy way to manage their website.

As a starter the minimal package will be perfect for you, you can always switch to a dedicated server if shared services can’t accommodate your growing traffic.

When you choose your first web hosting look these features even if you don’t think you are going to need them; as your business grows you will certainly need it.

  • Disk space – this should not be a problem, as most of the companies will give you plenty of space or even unlimited space.
  • Technical support – you need good technical support that you can rely on if something happens. 24/7 support is desired so you don’t have to wait the next day to fix your website.
  • Email support, auto-responders, mail forwarding will be great marketing tools.
  • FTP is a definite requirement, SSH connection could be needed, Control Panel is an excellent tool for administration you should choose a package that provides it.
  • Multiple domains and sub-domains will help you pay for a minimal single package while testing various domain names.
  • Up-time is a measure of reliability of a web site. 99.5% or more is a good up-time.
  • Web-site speed – can be determined by a series of factors of which the important ones when picking your hosting company are: the Internet Connection Speed of your host, the number of customers that share a server, the resources taken by the other customers that share the server with your web-site, the capability to partition hardware so that CPU and IO are equally shared between customers, (some companies use a CPU throttling mechanism).
  • Support to database, PHP, ASP or ColdFusion and Perl.
  • Price is very important, at least at this stage, but don’t go for the cheapes just because of the price. All the previous aspects are more important.
  • Try to go local, the language barrier, the time-zone sometimes make a difference. Also it will be faster for your clients to access a local provider than a server located on another continent.

It is important that you focus more on the content of the website and running the business and not on developing the website and learning PHP or ASP. That’s why you have to look for a Control Panel that contains the ability to install a CMS, (Content Management System), such as Drupal or Joomla or even WordPress.
