The first thing you will need to change for such a test is the number of simultaneous connections accepted by the Apache web server: by default the max is 256. See the Apache documentation here: https://httpd.apache.org/docs/2.4/mod/mpm_common.html#maxrequestworkers In addition I also sugges

Re: [ovirt-users] Tunable parameters in ovirt engine

Hi Juan, Thanks for the response. I agree web server can handle only limited number of concurrent requests. But Why it is failing with SSL handshake failure for few requests, Can't the JBOSS wait and serve the request? We can spare the delay but not with the request fails. So Is there a configura

Re: [ovirt-users] Tunable parameters in ovirt engine

With the default configuration of the web server it is impossible to handle more than 256 *connections* simultaneously. I guess that "ab" is opening a connection for each concurrent request, so when you reach request 257 the web server will just reject the connection, there is nothing that the

It means that with the default configuration the Apache web server can't serve more than 256 concurrent connections. This applies to any application that uses Apache as the web frontend, not just to oVirt. If you want to change that you have to change the MaxRequestWorkers and ServerLimit param

Re: [ovirt-users] Very Slow Console Performance - Windows 10

Hi I don't think these issue have much to do with Spice, but with the amount of memory oVirt sets to VMs by default, which in some cases for desktop usage seems too little. A field where that could be adjusted without having to edit files in the Engine would probably resolve this issue, or am

If you are still having problems I am inclined to think that it is a client issue. For example, I'd try to remove the "-k" option from the "ab" command. If you use keep alive the server may decide anyhow to close the connection after certain number of requests, even if the client asks to keep i
