Chekutanga chakashandiswa mumutsara wekuparadzanisa marara. Roller sefa inoshandiswa kugadzira marara ne granularity
Midziyo yekurongedza michina yakarongwa. Pamusoro peroller yese pakaboorwa maburi ehukuru hwakasiyana. Muviri wechidzitiro wakaiswa wakamonereka, uye zvinhu zvinopinda muroller.
Kutenderera kuri nyore nekutenderedzwa mukati kunoita kuti kutenderera kwedenderedzwa, marara ane saizi yezvidimbu zvidiki pane buri rekusefa anoseferwa muchikamu chiri pasi pesefa, uye anogara mumuviri wesefa.
Zviri mukati zvinova sefa uye zvinoburitswa pasi pemupumburu.
