Re: Tomcat access is very slow
Mike, you'll probably get a few comments about thread hijacking - might be worth starting a new thread. Is there any way you could get a Wireshark or similar trace? It'd be very interesting to know what bytes the browser sent when in the request, for example, and whether the browser half-closed the socket. Also, which Connector are you using? What happens if you use a different one? Cheers, - Peter On 3 February 2010 17:37, youngm wrote: > > I am having a similar problem though I only see this problem in Google > Chrome.

Re: Tomcat access is very slow
I am having a similar problem though I only see this problem in Google Chrome. I request my home page in chrome and it takes 100 sec to load the page. If I load the page in Firefox it loads excellent. I downgrade to tomcat 6.0.20 and everything works great in chrome. This is hitting a server using "localhost" so it's not a host resolve/timeout problem. I hooked a profiler up to my app running tomcat 6.0.24 and hit the home page. All of the time is taken in the following trace. org.apache.coyote.http11.InternalInputBuffer.parseRequestLine() org.apache.coyote.http11.InternalInputBuffer.fill() java.net.SocketInputStream.read(byte[], int, int) [Wall Time] java.net.SocketInputStream.socketRead0(FileDescriptor, byte[], int, int, int) Tomcat 6.0.24 is spending 100 sec 99% of the request in the socketRead0 call above. Again I don't see this problem with Tomcat 6.0.20 in any browser. In Tomcat 6.0.24 I have tested Firefox 3.5, IE 8 and Chrome 4.0.249.78. I only see this problem in Chrome. Any ideas?

Might be network timeouts, waiting for something like DNS resolution (as someone else already suggested, I believe). Compare the C:\WINDOWS\system32\drivers\etc\hosts files on the two computers, and perhaps run Wireshark on yours to see if there are network requests being made that are not being responded to. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

Re: Tomcat access is very slow
thank you. 1. XP 2. 1.5.0 3. I have a tomcat project, which is running fast on my colleague's computer, but very slow on mine. 4. examples is very fast. 5. no database, but webservice. 6. IE, chrome, firefox, i tried all of them, same result. I even copied my colleague's tomcat to my computer, but doesn't work, it's very slow when I accessing http://localhost:8080/projectname, it takes 5 minutes to open a homepage, but in my colleague's computer, only 10-20 seconds. 2010/1/27 Konstantin Kolinko > 2010/1/26 Yu Chao : > > sorry for my later response because I reinstalled my computer... the > > situation is still slow, I got mad... > > 1.

Re: Tomcat access is very slow
some complementary: 1. Tomcat startup is very fast, in 5 seconds, but slow in access pages. 2. I changed 5.5.28 to 5.5.23, both very slow. 3. 2010/1/16 Yu Chao > Dears, > > > > I’m not a very new to Tomcat \with a few projects experience. > > I got a new note book, everything is very fast except tomcat access. > > > > I run a new project in my new tomcat(5.5.28 with no other project in > webapp), I need about 2-5 minutes to open a page. > > Same environment on my colleague, it only need 10 seconds at most. > > > > Some colleague said they met this situation before, but when they reinstall > the OS, it works well, > > Do I have any other ways except reinstall OS? > > > > Thank you in advance, following is my environment configuation. > > > > HP 4311s with 2G Memory > > Tomcat 5.5.28, new and clear. > > No virus. > > > > > > Best Regards, > > Yves > > >
Tomcat access is very slow
Dears, I’m not a very new to Tomcat \with a few projects experience. I got a new note book, everything is very fast except tomcat access. I run a new project in my new tomcat(5.5.28 with no other project in webapp), I need about 2-5 minutes to open a page. Same environment on my colleague, it only need 10 seconds at most. Some colleague said they met this situation before, but when they reinstall the OS, it works well, Do I have any other ways except reinstall OS? Thank you in advance, following is my environment configuation. HP 4311s with 2G Memory Tomcat 5.5.28, new and clear. No virus. Best Regards, Yves
