You need catalog URL rewrites to make your catalog work properly. Also it takes too much of time to execute. most of the time it failed due to php maximum execution time settings. If you don’t know how to set it or if you don’t have permission to do it, here is another simple solution…

Step01: First you need to log in to your server.

then enter your password

cd yourmagentofolderName

Step03: simply type below command

php shell/indexer.php reindexall

Apache Webserver Benchmark

Hello friends..

today i’m going to introduce simple apache webserver benchmark tool. its called ‘ab’. as abbreviation implies its “apache benchmark”. It provides a quick an easy way to evaluate your http serving capabilities. ab overloads the server with http requests and measures the time it takes to serve all those requests.

Install ab

ab comes preconfigured with your apache installation. Apache by himself is just an extension command for the Apache Web Server. So if you have already installed Apache, then you should be able to run ab.

Usage

$ ab -n 1000 -c 5 http://192.168.0.101/

# n 1000: ab will send 1000 number of requests to server 192.168.0.101 in order to perform for the benchmarking session
# -c 5 : 5 is concurrency number i.e. ab will send 5 number of multiple requests to perform at a time to server 192.168.0.101
