Latency after COLDFUSION 8 upgrade

Hi, We upgraded to CF8 for our large Enterprise Application and have seen our application to be slower than before. Immediately after the upgrade the server would not even render any pages (it was painfully slow), after doing some research, (thanks for CFtalk) we found out about the conflict with JDK 1.6. We downgraded to 1.5 and the system speed has been OK, but nothing great. Any guidance on what we should be looking at to resolve the latency issues we are experiencing with CF8 would well appreciated. Thanks

Be sure server monitoring / memory profiling / debugging are disabled on the new server ;) Chris Hi, We upgraded to CF8 for our large Enterprise Application and have seen our application to be slower than before.

Chris, Server monitoring and profiling were already off but debugging is on. Is there is difference in the impact that debugging has between CFMX7 and COLDFUSION 8? thanks ----- Excess quoted text cut - see Original Post for more -----

Chris is right.  You shouldn't have debugging turned on for a   production server - especially with "Report Execution Times" enabled.   I do know that debugging on CF8 returns much more information than on   CF7 if you have it configured for the full output.  It would make   sense that the increase in information would correlate to an increase   in overhead.   Also, are you using a third-party database driver or   one which is native to CF8.   If the former, you might want to check   the driver as well.

We are using DB drivers native to CF; Also to be sure that there is no impact, we have turned off debugging completely. No luck yet :( ----- Excess quoted text cut - see Original Post for more -----

Turn debugging off on production servers. You can enable the left most of the three monitor options in the server monitor without issue. -- Tom Chiverton **************************************************** This email is sent for and on behalf of Halliwells LLP.

Yes, debugging is completely off. thanks ----- Excess quoted text cut - see Original Post for more -----

OK.   That makes it more interesting.... Next step is too look at the operating system and permissions.   Are   you on Linux or Windows?  If Linux, what distro and is it a supported   distro for CF8 (I've run into problems on SUSE, for example, that   didn't occur in RHEL)? For Linux servers you should also 'chown' the cfusion logs directory   to ensure there aren't any permission conflicts when attempting write,   rotate, or append the log files.
