Re: T5: ClasspathResource and performance
Hi all, Thanks for your answers. I've already stripped down the supported locale list to the only one needed. We still have two missed hit for each tried locale. The tapestry.file-check-interval doesn't help either. The file-check-interval is seems to be used only for existing files. I guess the decorator will do the trick. Thanks.

Re: T5: ClasspathResource and performance
Hello
i have already encounter this kind of problem, we solved it by using a
decorator to cache asset access with something like, it was for Tapestry
5.0.18 :
public class AssetSourceCacheDecorator implements AssetSource {
private final MapMultiKey, *Asset* cache =
CollectionFactory.newConcurrentMap();
private final AssetSource delegate;
public AssetSourceCacheDecorator(AssetSource delegate) { this.delegate =
delegate; }
public *Asset* getAsset(Resource baseResource, String path, Locale locale) {
MultiKey key = new MultiKey(path, locale); if (cache.get(key) == null) { *
Asset* *asset* = delegate.getAsset(baseResource, path, locale);
cache.put(key, *asset*); return *asset*; }
return cache.get(key); }
public *Asset* getClasspathAsset(String path) { return
this.getClasspathAsset(path, null); }
public *Asset* getClasspathAsset(String path, Locale locale) { return
this.getAsset(null, path, locale); }
}
Regards,
Christophe.

Re: T5: ClasspathResource and performance
Also on there is the tapestry.file-check-interval which specifies how long Tapestry should wait before rechecking for changes. In production, I set that to 1y because the files aren't going to change. However I don't know if this affects asset loading or not, but I *think* that once the first hit returns null it won't keep checking? It's worth a try and it certainly won't harm.
