« 00483 | Issues | 00485 »

Summary: improve performance in cev_overlay_comm.tcl

Created: 2013–03–12 11:11

Status: Released

Category: Request

From: frankie

Version: 2.3

Released_In: 2.4

Description:

After some profiling of the DOUG code, it was noticed that the tcl events being fired from within cev_overlay_comm.tcl were taking longer than expected. After some investigation, it appears that this is mainly due to the regsub calls that get executed every time the event fires.

This is a request to improve performance of the cev overlay code.

Removing these by remembering the calculated variable names after init seems to improve things quite a bit. The max execution time on my laptop for the tcl events went from 0.0081 seconds to about 0.0013 seconds. @] |
