The old VLSI Technology Inc (later Philips, now NXP) reference manuals for one of the first ARM processors (the one used in the Acorn Archimedes 305, 310) mentioned that the algorithm used for cache eviction was not something relatively predictable like LIFO or FIFO but essentially random. Which in theory means that if you were 'unlucky' then your program would run slower than for a luckier person etc.
