Subject Re: [Studio] Switch the 'default' property value of the LDIF Editor extension to 'false'
Date Fri, 10 Dec 2010 17:47:22 GMT
I quickly benchmarked the cost of the file check, it's almost insignificant...
It takes around 50ms to validate/invalidate a file (checking the first 10 first entries)...

Our LdifReader is quite fast! :)
