I had made some measurements for non-DOLT and DOLT case for the current libX11 case. Here are the results of ministat spawned for data from 10 compilation cycles with DOLT and without DOLT: (fully warmed disk cache, almost zero activity on the machine, all resources are dedicated to the port building): ----- x noDOLT.real + withDOLT.real +------------------------------------------------------------------------------+ | ++ | | ++ x | | +++++ + x xxx xx xxx| ||______M_A_________| |___A____| | +------------------------------------------------------------------------------+ N Min Max Median Avg Stddev x 10 177.48 189.25 184.365 184.366 3.5870173 + 10 135.01 159.06 137.345 139.211 7.0399976 Difference at 95.0% confidence -45.155 +/- 5.24948 -24.492% +/- 2.84732% (Student's t, pooled s = 5.58696) ----- I'd say that 45 seconds (24.5%) speedup worth some patching.
