Savochkin for his patch for my problem with Electric Fence that I posted on August 20 for 2.1.xxx. Though still slower than 2.0.xx, the patch looks like a big improvement for 2.1.xxx, running my Electric Fence example over 10 times faster. The patch didn't apply against 2.1.116-2.1.119, so the new results below are for the patch applied to 2.1.111 (the only earlier 2.1.xxx that I still have). Elapsed time in seconds 2.0.34 2.1.117 2.1.111-patched ----------------------- ------ ------- --------------- Without Electric Fence 3.82 3.72 3.76 With Electric Fence 14.61 325.85 29.73 The improvement is very much appreciated.
