I do disagree what some of Araunah statements, however, I know for a fact that dreamshost does oversell, ALOT. Some servers have 800 customers on them, but they are perforance servers. I host a handful of sites that get over 12,000 hits a day and you can tell the difference in performance during peak-hours and non peak-hours. My sites seem to handle the load pretty well, even with multipul digg bombing.
Having said that, I think zen cart itself (probably with dreamhost server config) is slow. I run 2 ecommerce sites from my server, and I'm sorry to say that cubecart performs much better. I much prefer the feature rich zen cart, so what I have done is optimized the code down to even the most miniscule details.
- Dropped the standard store theme and built a simple yet stylish storefront via CSS, then compressed the file to bring the file size way down.
- Compressed the .js files
- Optimized the template code.
- Kept images to a minimum.
- etc...
knuckle-101 - their servers are very well optimized. But zen cart is bulky, and their servers a geared to handle a moderate number of connections to hundreds of users at a time. Sure their "not optimized to help you", but they are optimized to give the best performance for everyone on the server.
But for $9 a month, why complain. I'm satisfied with my dreamhost experience, but if Verizon ever wanted my to host their website, it certainly won't be on shared server.
