Re: Tomcat response time extremely high (minutes)
Hi Rapthor, I'm having similar problem. Has your isue resolved? Can you share the resolution?

Tomcat is slow with router configured
Hi Tomcat experts, I have a war file deployed in a Tomcat server (Jakarta-tomcat 5.5.9) running on a windows server 2003. Web server accesses MySQL server running on a different box, also Windows server 2003. The web app is fast if I configured network bridge mode (both Web server and DB server have same subnet 192.168.1.x). But it is very slow if the network is configured as router mode (Web server and DB server is in different subnets - 192.168.1.1 for web, 196.168.2.1 for DB, the 2 boxes communicate via a router device). Is there settings in Tomcat to deal with this? I tested MySQL client running on Web server side. MySQL client is very fast for both bridge mode and router mode. I also tested the file transfer. The MS ftp is very fast for both bridge mode and router mode on the 2 boxes. I appreciate very much for your help TT -- View this message in context: http://www.nabble.com/Tomcat-is-slow-with-router-configured-tp14408452p14408452.html Sent from the Tomcat - User mailing list archive at Nabble.com. - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: Tomcat is slow with router configured
Hi all, Thanks for your inputs. The issue is at MySQL. With router mode, even using IP address, MySQL sends TCP messages to resolve hostname. The threads are timed out after each one. It runs fast after I disabled host name resolve my MySQL server. I got the information from this forum. http://www.nabble.com/Connections-from-localhost-fast.-Connections-anywhere-else-slow.-to129994.html#a143316 Thanh Peter Crowther wrote: > >> From: Gary Evesson [mailto:[EMAIL PROTECTED] >> Try using the IP address in the driver specification rather >> than the name of >> the machine.
