The second run is so much faster because Photoshop already has allocated the 15GB or so of memory it needs already and has it ready for use. On the second run, CPU usage is green, this indicates “application time”. This indicates “system time” eg operating system calls eg memory allocation. This U3D memory corruption vulnerability (CVE-2011-2462) could cause a crash and potentially. In the CPU History graphs from Activity Monitor below, observe that most of the CPU usage is red. A critical vulnerability has been identified in Adobe Reader X (10.1.1) and earlier versions for Windows and Macintosh, Adobe Reader 9.4.6 and earlier 9.x versions for Linux, and Adobe Acrobat X (10.1.1) and earlier versions for Windows and Macintosh. Closing the test file (but not quitting CS5), then reopening it and running it again is far faster, with far better CPU utilization.

On the second run, CS5 already internally has that memory allocated and ready to go it doesn’t need to ask Mac OS X for it.ĬS5 needs to be “ warmed up” so to speak. On the first run, Photoshop steadily allocates the memory it needs for running the diglloydMedium Benchmark (about 15GB of real memory). The explanation involves memory allocation. That’s a serious performance problem that Adobe needs to address. Photoshop apparently has an overhead of about 60 seconds for the same memory allocation (see Warm-up). So that is the “lower bound” on what can be expected for time.

MemoryTester’s 'stress' command can allocate and clear 16GB of memory in about 9 seconds (Mac Pro 8-core, 24GB).

Memory allocation of very large quantities of memory is slow. Why the first 64-bit test run is so horribly slowĪs discussed above, CPU core utilization was seen to be atrocious. In other words, about 70-80% of the processing power is simply not used- wasted. For this test, Photoshop CS5 averages roughly 170% CPU usage (taking duration into account), out of 800%. Setting aside virtual cores (hyperthreading) which is slightly better than useless, maximum CPU usage is 800% on the 8-core Mac Pro Nehalem. These are horrible figures, but read on for an explanation. As it turns out, it was an Adobe Acrobat Reader DC installation glitch. Here is approximate CPU usage for each operation as the diglloydMedium benchmark was run: This way when the RAM is full, space on the C: drive will be used as virtual. There was also ample system memory free at the end of the run, about 5.6GB.

The diglloydMedium Benchmark was run on the 8-core 2.93GHz Mac Pro, and CS5 was given 16GB memory- more than enough, and during the test no disk activity was observed, so Photoshop CS5 was “free to run”.
