Speed comparison of pplacerand RAxML's EPA algorithm. Time to place 10,000 16 s rRNA reads of median length 198 nt onto a reference phylogenetic tree, with a 1287 nt reference alignment. "Γ model" refers to a four-category gamma model of rate heterogeneity [17], and "CAT" is an approximation which chooses a single rate for each site [76]. Tests run on an Intel Xeon @ 2.33 Ghz.
