Layout XL SKILL functions extremely slow in L environment

Yaosan

Is there any way to make XL functions (those with prefix "lx") run faster in the Layout L environment, for example by loading the necessary context manually? Here's the speed difference (in CPU time) as measured by the profiler for the lxComputeViaParams function used in a script (this function is called multiple times):

Layout L: took 0.71 seconds to run

Layout XL: took 0.06 second to run

Any suggestion? Thanks!

    And by the way, in my case it was 0.4 seconds for looking at 10 different viaDefs; once I'd looked at each once, it was much faster. 0.04 seconds for the first time to access each viaDef doesn't sound "extremely" slow to me.

    Regards,

    Andrew.
