Magento Ecommerce, “Please Wait”… and Wait… and Wait

By Jon Saints - 01 Sep 2009

I installed Magento http://www.magentocommerce.com on a dedicated server with 2 Xeon processors and 4 GB of RAM. Often when adding products, editing them, or choosing a category in the admin Magento takes 5-10minutes to complete the Save operation. A “Please Wait” modal dialog appears for long periods of time while Magento is thinking. The operation always completes without error, but It often takes 5-10 minutes just to save a simple product. I [asked for a solution in the Magento Forums](http://www.magentocommerce.com/boards/viewthread/53594/) and found one… Following the the instructions in the DYI tuning section here http://www.magentocommerce.com/blog/comments/performance-is-key-notes-on-magentos-performance/ I installed each optimization individually to see which made the difference. I found the following: - Apache KeepAlives enabled. This seems to help the category selection pages load much much faster. - Modify the configuration for your MySQL server. No noticeable gain on performance. Products still take 5 minutes to save. - APC or XCache. This one fixed the problem. Installing xcache seems to have fixed the problem. Products now save in about 2 seconds. Edit on November 15th, 2009: I found this in the Magento System Reqs: “Memory_limit no less than 256Mb (preferably 512)” Also please see: 1. http://www.magentocommerce.com/blog/comments/understanding-magento-scalability-and-performance-1/ 1. http://www.magentocommerce.com/whitepaper
