The transition from D5 to D6 was hard for us. We are now doing D6 to D7 and it is much harder. D8 is in progress and when released D6 will not be supported. Unless yours is a very small site or you expect it only be around for 1-2 years, D6 is an alternative. Otherwise go with D7. On Thu, Sep 20, 2012 at 7:28 AM, Gerald Klein <jk@zognet.com> wrote:

Although I have found 7 to be slower then 6, the improvements are worth the trouble. If you use an opcode cache like APC, you can negate some of the extra bootstrap code that causes the slower response. Depending how often code changes using something like Varnish will help also.

Hi Drupal Experts Is there any performance comparision data available between Drupal 6 and Drupal 7. If somebody need to start a developemnt for a big site (involving huge database operations, search engine tika/apachesolr etc), which one is recomonded D6 or D7.

Thanks a lot. Austin

Hi Jerry, Nancy, Daniels Thanks a lot for input. By the way Jerry, you mentioned 2 steps to make D7 better in regard to negate the slowness. 1. Use of opcode cache like APC 2. Use of Varnish Is there any other such options one need to look at to improve the performance? I have no idea on APC or Varnish. Does D7 provides any configuration to choose these things, or we need to apply any particular configuration to web servers. Jerry it will be so nice of you, if you can provide more info. Thanks a lot. Austin On Thu, Sep 20, 2012 at 6:34 PM, Ms. Nancy Wichmann <nan_wich@bellsouth.net>wrote:

I have not really noticed D7 being any slower, but some people say it is.

I will not start any more D6 installations, and have not since last Fall. If you can't identify a key module that is not available in D7, I would not even consider D6.
