I just tried to point out that it causes overhead which might slow down things. Which can be acceptable if you do not want to modify the ofbiz code. >> IMO turning off a cache should not cause this behavior. >> IMO turning off means just dont do anything with that specific cache, >> as if it never existed. >> So I would not consider this as a real substitute or workaround. > Only for developement, are you really suffrering of slowness in > development ? No, but I use my little modification which actually gets rid of the BeanShellScripts cache. This is a real turn-off with no overhead. Currently hardwired, but with a little more coding it could easily be controlled via properties, if needed. Could be applied to all caches not just BeanShellScripts. >> >> Btw this overhead/brake thing is indeed mentioned on this wiki page: >> http://ofbizwiki.go-integral.com/Wiki.jsp?page=Optimizing >> --------------------------------------------------------------------- >> However, here are some things you should do in every production > system: >> 1. comment out the settings in cache.properties that effectively > disable >> the FTL, BSH and other caches by setting their timeouts to 1ms >> (this is great for development, but wreaks havoc on a production > server) >> --------------------------------------------------------------------- >> >> (Also a bit of contradiction here.

The section tells things you should do in prd. 1st bullet tells about commenting out things which will cause overhead and wreak havoc in prd. This is obviously something you do not want to happen, therefore I would not consider it as a 'should do'.
