We present experimental results on the counting rate measurements for several single-gap ¹⁰B‑RPCs with anodes made from standard float glass, low-resistivity glass and ceramic. The measurements were performed at the V17 monochromatic neutron beamline (3.35 Å) at the Helmholtz-Zentrum Berlin. For the ¹⁰B-RPCs with 0.28 mm thick float glass a maximum counting rate density of about 8×10³ Hz/cm² was obtained. In the case of low resistivity glass and ceramic, the counting rate density did not deviate from linear dependence on the neutron flux up to the maximum flux available at this beamline and exceeded a value of 3×10⁴ Hz/cm².
