Internet users are impatient. A Zona Research study found
that if your site doesn't load in 8 seconds, up to 1/3 of your visitors
will leave.
Faster is Always Better!
Savvy eBusinesses recognize that simply having a Web presence is
no longer enough to succeed. They need reliable high-performance
Web sites that load quickly. If you have a business on the web you
know how important your site loading speed is. If your pages do
not load swiftly then you are losing money.
What we can do
At ImHosted.com™ our customer's enjoy faster page loading and script
execution thanks to caching & compression technologies we've
installed. Our servers run on industry standard content acceleration
software from Zend™, IntenseSpeed™ and HyperSpace Communications.
Together they make ImHosted.com™ server's incredibly fast and efficient.
Cache
The first technology we use to speed up our server is a method known
as caching. Caching engines are implemented to reduce page loading
time and script execution by performing optimizations and various
types of caching, using advanced techniques that yield much better
performance -- usually from two to four times more requests per
second. These engines also play an important part in cutting down
latency by as much as 20-fold, by preventing dynamic pages from
doing any repetitive work, and reducing the turnaround time for
each request.
Compression
 The second method
we use to boost our server performance is mod_gzip, a compression
module which uses the standard zlib compression library to compress
output. The idea is to compress data being sent out from the Web
server, and have the browser decompress this data on the fly, thus
reducing the amount of data sent and increasing the page display
speed. Using HTTP compression, a performance gain of 150-160% is
achieved across all ImHosted.com web servers. Using HTTP Compression
web pages can be 90% or so smaller and images can be up to 50% or
so smaller (depending on how much they are compressed already).
More information about HTTP compression can be
found here.

Benefits of Cache & HTTP Compression.
- Improves site loading speed
- Higher transaction rate
- More stability for your hosted site (reduces system
and CPU load)
- Run more server side scripts, faster (PHP/CGI)
- Up to 300% performance boost on script executions
- 150%-160% performance gain on static/dynamic content
- Bandwidth is conserved
