Dag, this is great work -- could you please open a bug for this? -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Dag Liodden Sent: Thursday, January 08, 2004 2:37 PM To: [EMAIL PROTECTED] Subject: Re: [OS-webwork] Xwork/WebWork2 under extreme load
I think that using the taglib is slow due to the massive amount of template parsing that is associated with rendering of the tags. By default, Velocity does not cache templates and so each tag will result in loading and parsing the templates. I've done a very simple stress-test with profiling and turning on resource increased performance noticeably on results with extensive use of the taglib (e.g a large input form). Mathias, since you obviously have a test-harness ready to go, perhaps you could turn caching on and give us some figures? Below is a simple Velocity configuration that goes into velocity.properties in WEB-INF with caching turned on. The modificattion interval is in seconds and could probably be adjusted up too (I use 2 seconds since it's adequate for development) - I think zero means never refresh but I can't really remember from the top of my head. -- Snip -- velocimacro.library = VM_global_library.vm,tigris-macros.vm runtime.log.error.stacktrace = true runtime.log.warn.stacktrace = true runtime.log.info.stacktrace = true runtime.log.invalid.reference = true # Resource loaders resource.loader = file, class file.resource.loader.description = Velocity File Resource Loader file.resource.loader.class = org.apache.velocity.runtime.resource.loader.FileResourceLoader file.resource.loader.path = .,WebRoot file.resource.loader.modificationCheckInterval = 2 file.resource.loader.cache = true class.resource.loader.description = Velocity Classpath Resource Loader class.resource.loader.class = org.apache.velocity.runtime.resource.loader.ClasspathResourceLoader file.resource.loader.modificationCheckInterval = 2 file.resource.loader.cache = true velocimacro.permissions.allow.inline = true velocimacro.permissions.allow.inline.to.replace.global = true velocimacro.permissions.allow.inline.local.scope = false velocimacro.context.localscope = false #----------------------------------------------------------------------- ----- # INTERPOLATION #----------------------------------------------------------------------- ----- # turn off and on interpolation of references and directives in string # literals.
