Perhaps lowering it a bit might give better results. DISCLAIMER: I haven't much experience with that, much less an idea what that might do to your box's security. The whole story is somewhere here [1]. Don't do that on your Internet facing server, less if it's running Apache. And so on ;-) Cheers [1] https://www.kernel.org/doc/html/latest/admin-guide/perf-security.html#u= nprivileged-users - t --AqsLC8rIMeq19msA Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Digital signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iEYEARECAAYFAmF2YVYACgkQBcgs9XrR2kaDxgCaAy0zAjB4Kl240cPmt5/tu3oQ tjYAmgM0S051VDHFw6yKVHPVcawFiqj5 =2Mez -----END PGP SIGNATURE----- --AqsLC8rIMeq19msA--
